Cant reboot or enter bios after flashing bios

May 28, 2009 at 18:07:22
Specs: Windows XP, 2gb corsair/intel core 2 duo

Well i've tried everything and have searched countless forums and am still at a loss. I was upgrading my comp, so of course i decided to flash my bios before installing the new hardware (cpu and memory). I downloaded the lates bios from abit for my motherboard, used the abit utility to install it, after the bios was updated it asks to restart, and i did. Well, when the comp restarted it went straight to a screen that asked for a floppy a drive. I tunrned the comp off, reset the cmos driver, tried to restart, didnt work. I unplugged virtually everything on my MB, including memory, cmos battery, HD, power supply, tried to start it, same prob. ive tried pretty much every combination of hardware being plugged in and not plugged in and i still get the same screen. Does anyone have any ideas? All i need to do is get back into my bios so i can reset my boot devices back to defaults, i hope doing that will allow me to get back into the op system.

From your description I can't tell if you got a bad flash or not. That said, you MUST always immediately enter the BIOS screens and reset values in the BIOS screens after you update a BIOS. Try that. Tap Del at start up.

First off thank you for the quick response!

Ive tried hitting the del key, and nothing happens. I dont even see my MB logo anymore where is says "hit tab to continue or hit del to enter the bios" it just goes straight to that screen.

USB or PS/2 keyboard?

Whichever it is, try the other type and see if using DEL gets you into cmos/bios setup.

tried using both. i first started out with my wireless usb, and for some reason it wouldnt work outside of the operating system, so i went to the store and bought a cheap little ps/2 keyboard and it works, but pressing delete still does nothing.

the screen that normally loads after a restart that lists all your hardware and such, the actual screen you'd press the del key doesnt even come up

i did not. i guess i thought since i was using the motherboard utility program to flash the bios it would do that for me.

so i guess the question is: what can i do if i flashed my bios but did not save the old bios on a disc

How about explaining how you went about flashing the BIOS. Here's how I normally do it:

- copy the BIOS file & flash utility (AWDFLASH.exe for example) to a formated floppy
- boot off a WinME boot floppy & select "minimal boot"
- when it stops at the A:\> prompt, remove the WinME floppy & insert the floppy with the BIOS file
- type AWDFLASH, press ENTER & follow the instructions

One common reason for failure is using the wrong files.

Is the computer fully assembled now?

If you can't get a PS/2 keyboard to respond to anything you are pretty much screwed. Your only chance then is IF you can get the computer to boot to a floppy again. Try disconnecting all other drives except the floppy. Verify that you have the correct flash and bin files for your EXACT board on the floppy and then see if you can re flash.

I doubt Abit will be of much help. They are closing shop on motherboard manufacturing.

I assume you still have the original CPU and RAM installed?

"bought a cheap little ps/2 keyboard and it works". How do you know that?

"it just goes straight to that screen". What screen, the Abit splash screen?

Worst case here is to replace the chip. As stated above I don't know if Abit is going to be helpful or not. You may have interrupted the flash process, thinking it was finished. I don't know.

jam,
i flashed the bios using the utility that came with the motherboard. Its called 'FlashMenu' U can update the bios from that software, without having to do what you described. you can 'Update from file' or 'One click Live Update' or "live Update Step by step. So what i did was download the latest bios from my MB website (abit.com) and i chose 'Update from file' After the install it asks to restart, so i did, and thats when i started having probs.

Othehill,
The comp is fully assembled.

When i start the comp this screen immediately loads
"Bios checksum error

Detecting floppy drive A media...
Drive A error. System halt"

That obviously means it cant find an A drive. So i plug in the A drive, then it says "disc failure, insert disc and press enter" and of course it says that because there is no disc in the. But i press enter any way and the same message immediately pops up, thats how i know my keyboard works. Because its responding when i hit the enter button.

I still have the original cpu and memory.
The abit splash screen never even pops up, that screen, plus the screen that lists all your hardware never even pops up...it just goes straight to that "..Drive A erro, system halt" screen.

Clear the CMOS using the jumper while unplugged. Then try to enter the BIOS using Del key. If that works then reset the values as needed.

I thought you stated above that you connected a floppy drive to the computer? Do you have a floppy drive or not?

Do I understand that you flashed the BIOS the first time while in WinXP?.

Post the exact model of your Abit motherboard, including version. That is marked on the board itself. Usually somewhere on the edge.

If all you need is a floppy disk with the correct files on it that shouldn't be an issue.

Verify the BIOS CAN be flashed using a floppy disk. The file may be different too.

That is why I asked for the complete model number with version. That info should be printed on the printed circuit board.

You will need a boot able floppy with the addition of the flash and bin files included. jam prefers an ME boot floppy, which yu can download from bootdisk.com.

It would help a lot if you stated which Abit mboard model you have.
Find the mboard version or revision that is printed on the surface of the mboard (see below for more about that).

If your mboard is recent enough, I have noted some recent mboards (e.g. Asus) come with a CD that when inserted will autoboot into a mode that allows you to recover the bios a lot more easily than the following. If so, there is probably info about that in the mboard manual for your model.
.....

"Well, when the comp restarted it went straight to a screen that asked for a floppy a drive. "

" When i start the comp this screen immediately loads
"Bios checksum error

Detecting floppy drive A media...
Drive A error. System halt"


That indicates the boot block portion of the bios code is loading. When you flash the bios, the boot block portion of the bios code is usually not flashed as well by default. It's there as a fail safe feature.
The boot block bios loads when something went wrong while attempting to flash the bios, or if you interrupted the flash procedure before it was actually finished, or if you tried to flash the bios with a bios version that was meant for a different mboard version or revision, AFTER you reboot after attempting to flash the bios.
The main part of the bios code is either corrupted, or it's for a different mboard version or revision - e.g. different mboard version or revision series often have different I/O chips and/or one or more different main chipset chips.
Clearing the cmos by moving a jumper then moving it back, or removing then re-installing the battery, cannot help , and the ability to press Del, if that's actual the key you normally press to get into the bios Setup (it might not be) , to enter the bios Setup cannot work, because the main part of the bios code is not there or is not usable.

The boot block bios code is looking for certain necessary files on a floppy in the floppy drive to flash the bios with - e.g. for an Award bios, a suitable flash utility, and a suitable bios version file, and possibly an Autoexec.bat file you have to make with a certain line in it to start the flash utility with certain switches. For an AMI bios you need only the bios update file but the file extension may have to be renamed, e.g. to *.rom.
If it doesn't find those files or that file on a floppy, the boot block bios produces an error message and goes no further.

The fact that you are getting the boot block bios message probably indicates the bios chip has not physically failed, which is a GOOD thing - sometimes the bios flash chip physically fails while flashing and that can only be recovered from by replacing the bios chip with a new one that has already been flashed, which is much cheaper and easier to do if the bios chip is in a socket and can be removed - e.g. there are vendors on the web that can supply you with a new flash chip that has already been flashed with the newest available mboard manufacturer's update. If your bios chip is soldered into the mboard and therfore not removable , that can also be replaced but that can cost more than buying a new, or used working, mboard, because you must ship the mboard someplace to have the chip replaced then have it shipped back.

You probably can successfully flash the bios and get your computer working again, but in order for that to work, you MUST have the proper files on the floppy disk.
Find the version or revision that is printed on the surface of the mboard - sometime's that's next to the obvious larger characters of the model, often between slots or in the middle of the mboard; sometimes that's elsewhere on the mboard - and make sure you have a proper bios update file for the right mboard version or revision, and if it's an Award bios version, the proper Award flash utility version, on the floppy. Sometimes newer bios update versions require you use a newer flash utility version along with them - if so that should be mentioned in the bios update's notes, and you may need to download and use that flash utility version rather than use one that came on the CD for the mboard or use the one that may be built into the bios.

Look at the manual for your Abit mboard model - the directions for how to load a bios update when a flash has failed and the bios is just the boot block bios may be in that. If not, there are probably directions on the Abit web site somewhere.
....

"...I can't get passed that error screen to win
xp to download and copy the bios to a disk."

The boot block bios has a minimal amount of code - it does not have the ability to boot your hard drive.

If it has a problem with the floppy drive you won't be able to boot from there so no bios upgrade that way until that's settled. Try the 'clear cmos' jumper process and see it that does anything.

One common symptom of a bad flash is a problem with the floppy drive. If you can get it to boot from another media--cd, USB drive, etc. you may be able to do the upgrade.

well i downloaded the same bios update that i installed, put it on a floppy, inserted the floppy and turned my comp on and its now saying:

Non-system disk, or disk error
Replace and strike any key when ready

So it sounds like it wants a boot floppy disk, not the updated bios.
The following are all the files that came with the bios update:

ABITFAE.BAT
AWDFLASH.EXE
M612A_18.BIN
M612A_18.TXT
RUNME.BAT

I put these all on the floppy. Jam suggested an ME boot disk. Should i not just download the win xp boot disk from bootdisk.com?

Assuming tbriar has the floppy data and power cable connected correctly, I don't think there's a problem with the floppy drive. The error message is probably because the boot block bios is not finding the proper files on a floppy in the drive.

tbriar

The floppy data cable can probably only go on the mboard header one way, if the connector has a blocked hole for one pin, and/or if the connector has an external tab on one side that lines up with a slot in the plastic header shroud - if it doesn't have any blocked pin holes, and/or if the outside of the connector has no external tab that lines up with a slot in the plastic header shroud, it can go on either way - in that case the stripe on one side of the data cable should be on the pin 1 end of the header - that's often marked with a V or an arrowhead or a 1 on the mboard surface .The floppy drive datacable connector may have no blocked pin holes and can often go on the floppy header either way because the header has no plastic shroud - usually the correct way is the striped side of the data cable is on the same side as the power connector. If the floppy data cable has 3 connectors, the single floppy drive must connect to the end connector.

If one end of the data cable is connected backwards and the power to the floppy drive is connected, the floppy drive led is on all the time the computer is running.

If the floppy drive data and power cable is connected correctly and boot block bios is recognizing the floppy drive correctly, while booting you will see the usual brief flash of the floppy drive's led, then it will come back on and stay on for a longer time - it's looking for the proper files on a floppy disk.

You download the bootdisk.com file and run it to create the bootdisk. But the only files you need are the system files--io.sys, msdos.sys and command.com. You need to delete all the files except for those. The first two are hidden files and won't show. Command.com will show.

Anyway, delete all the files except for those three. Then copy the bios flash files to the floppy disk. You'll have enough room now.

Or, on a 98 or ME computer, take a blank floppy disk, put it in a: and from START--RUN type sys a: and OK. (I think that'll work from the desktop. If not open a dos window and type SYS A: and enter. That will transfer only those three files to the disk. Then, as above, copy the bios flash files to the disk. You won't have to delete anything first.

. . . Of the bios flash files, you'll need to type in one of the files with a .bat extension from the a:\> prompt after booting with the bootdisk--runme.bat seems the most likely but you should take a look at the .txt file. It should give instructions. Or they'll be instructions on the abit download page.

abit fatal1ty f-190hd

Support - I assumed you bought in the USA:
http://www.abit.com.tw/page/en/moth...

NOTE that if you DID NOT buy it in the USA, the mboard version or revision and the corresponding bios updates MAY BE DIFFERENT - make sure you select the right country when you look up the support and bios updates for your model.

Bios (updates)

There seems to be only one mboard version or revision for this model - at least, there aren't any others listed.

For bios version Bios ID 13 and up -

"This BIOS does not support older version of FlashMenu.
Please update FlashMenu to V1.5.0.5 or later version prior making this update."

FlashMenu is what Abit calls it's Windows based flash utility. It's on the CD that came with the mboard, but you have to use a NEWER version with Bios ID:13 and up - you may have used an older version and that's why the flash failed.
If you DID use the specified newer version, things can go wrong when you use a Windows based flash utility - the safest way to flash is by using the bootable floppy method.

I checked by downloading one and looking at it's files with WinZip - the proper Award flash utility version is included with each bios update download - that you can use to flash using a bootable floppy disk, or it can be used by the bootblock bios.

In this case, if your bios weren't screwed up, you would simply boot with a bootable floppy that has all the files included in the bios update download on it and type:
Runme (press Enter) . That won't work because the boot block bios can't process keyboard input.

Abit doesn't seem to have any info about what you do when you have the boot block bios situation on their web site or in the manual for your model.

From: http://www.badflash.com/faq.html

"Q. I flashed with the wrong file.
(my note - or the flash was not successful)
Is there any way to recover?

A. If your floppy drive seeks on power up and then stops after a short period of time, you may have a chance to recover. The following information was obtained from Wim's Bios http://www.wimsbios.com/ FAQ's. Corrections on AWARD Bios by Terry McGuire.

Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automatically by putting AWDFLASH *.bin /sn /py /cc /r in the AUTOEXEC.BAT file. The * would be the correct bios .bin file and there must be spaces between the slash marks. Put it in the floppy and turn on the computer when the floppy seeks it will load the correct bios and reboot by itself. When it finishes you have to remove the floppy and enter the cmos SETUP and modify the CMOS for your configuration."

In M612a-xx.txt in the extracted bios update files, where xx is the specific BiosID number, it says:

"Please notice that we suggest you flashing the bios with switches

/py /sn /cd /cp /cc /cks /R

I recommend leaving out /R.
I think that's for reboot - if so, the computer will reboot automatically after the bios has flashed successfully - if you DO use it be ALERT and eject the floppy if it does auto reboot, BEFORE the floppy drive is accessed while booting. If you miss dong that at the right time, DO NOT eject the floppy disk or you might trash the bios - let it flash the bios again. For that reason I do not recommend using the reboot switch.
The RunMe.bat file that you use when your bios is working properly, which runs the Abitfae.bat file that actually flashes the bios does not use the /R switch


After BIOS updated, pull off the power cord and then clear the CMOS data via jumper before restarting system please."

More detail - How to clear the cmos properly.
http://www.abit.com.tw/faq/index.htm
......

1.It's critical that there be nothing wrong with the floppy disk you use - sometimes they have undetected bad sectors on them these days - the quality control of them isn't as good as it used to be.
To check it, I recommend you format the floppy you are going to use - DO NOT use the Quick format switch - a full format is very good at finding previously undetected bad sectors. In XP, RIGHT click on A with the floppy in the drive, select Format, nothing else.
When the format has finished, RIGHT click on A, choose properties - it should say 1,457,664 bytes - there should be no bad sectors - if there are bad sectors, don't take any chances - start over with a different floppy disk.

2.When you have a floppy disk with no bad sectors, Format the disk again, and in XP select only Create a MsDos Startup disk.

Copy Awdflash.exe and M612a_xx.bin from the bios update download contents you extracted to the floppy, xx being the specific Bios ID number of the bios update you're using

4. Create a text file on the floppy - type the line that runs the flash utility on the bios update, all on one line.
Save the file as Autoexec.bat

NOTE that if the common file extensions are not visible on the computer you are making the file on, you must go to Control Panel - Folder Options - View and make them visible, otherwise you will be making the filename Autoexec.bat.txt instead of Autoexec.bat.

e.g.
Awdflash M612a_xx.bin /py /sn /cd /cp /cc /cks
xx being the Bios ID number of the bios update you're using, and there is a space between everything -
between Awdflash and M612a_xx.bin
between M612a_xx.bin and /py
between /py and /sn
etc. etc.

5. Boot your computer with the prepared floppy flash disk in the drive. The boot block bios should automatically let the flash utility update the bios.
You should see the floppy led go on and off.

You probably won't see anything graphical.
You may or may not see progress messages or a message that the flash was successful.
The mboard may or may not beep when the flash is successful.
Keep in mind sometimes flashing a bios is really SLOW - it may take 5 minutes or more.
If you see or hear no indication the flash was successful, WAIT at least 5 minutes AFTER the last time the floppy led flashed, then eject the floppy and reboot the computer.

If you used the /R switch, I think that's for reboot - if so, the computer will reboot automatically after the bios has flashed successfully - be ALERT and eject the floppy if it does auto reboot, BEFORE the floppy drive is accessed while booting. If you miss doing that at the right time , DO NOT eject the floppy disk or you mat trash the bios - let it flash the bios again. For that reason I do not recommend using the reboot switch

6. When you reboot, you will get a CMOS CHECKSUM ERROR or similar message, but if the flash was successful, you will be no Boot Block Bios message after that, and you will be able to enter the bios. Go into the bios Setup and set at least the date and time - that will stop the CMOS CHECKSUM ERROR or similar from appearing when you boot after that, and LOAD BIOS DEFAULTS, save settings.
OR
Abit recommends your clear the cmos (see the link above), in which case next boot you'll get the CMOS CHECKSUM ERROR or similar error, and will have to go into the bios to set at least the date and time, but bios defaults for the specific bios version will be loaded by default.

7. You computer should boot your hard drive properly, if the default boot order settings are correct for your situation - if not you'll have to go into the bios and set the drive you want to boot from as the first one in a list of hard drives.

I recommend you set the boot order to floppy drive first, if you have and use one, CD drive second, hard drive third - that works for most bootable disk or drive situations without you having to change boot order settings.

A CD drive does not have to be listed first in order to boot from it as long as it is before all hard drives.
In all the bioses I've tried it in, admittedley mostly older ones, listing a floppy drive after a CD drive does not allow a bootable floppy to be recognized while booting.

Flashing the bios can be quite SLOW - see 5. in response 31.
Your mboard has a relatively large bios. The *.bin file is compressed - it has to be uncompressed - in this case the max speed at which that can be done is at the relatively slow speed at which a floppy drive runs. Typically the expanded bios is 8X as large as the *.bin file - your *.bin file is 1,048,576 bytes - 1mb. .

Yes, it appears something went wrong.

I was assuming there's nothing physically wrong with the bios flash chip - maybe there is something wrong with it.
Or maybe something else wasn't right.

If you hold the power button in for at least 4 seconds, the mboard will probably shut off.
If it doesn't, you'll have to switch off the power to your computer.
Eject the floppy.

The mboard manual is probably on the CD that came with the mboard.
Or you can download it here:
Manual:
http://www.abit.com.tw/page/en/down...

Take a look at the Cmos jumper and make sure it's on both pins.
Take a look at the mboard battery to make sure it's installed right - the + polarity mark on the battery must be upwards where you can see it, and the battery should be touching it's contacts properly.

If both of those are ok, something else is wrong.

You could try clearing the Cmos, but I don't think it will help.

How to clear the cmos properly.
How to do CCMOS Action
http://www.abit.com.tw/faq/index.htm
.....

Make sure the flash floppy is ejected.

When you attempt to boot, you will probably still have the boot block situation. You will get the CMOS CHECKSUM ERROR or similar and the Boot Block Bios message, and the floppy led should come on after the initial usual brief flash while booting.
If so, you could try flashing again.
If not, see below - Replace the bios flash chip.

- It could be your flash floppy had undetected bad sectors on it, if you did not check it as I suggested in response 31. In my experience, as many as 20% of floppy disks I have bought in recent times had undetected bad sectors on them, and some that didn't initially have them developed them in a short time. In that case the files you copied to the flash floppy may have been placed on bad sectors.
If you didn't check it, see 1. in response 31.

- Your bios download may have been corrupted. Download it again, and extract it's files. Or - choose another source (country) when you download it (you must still access the support for the country you bought the mboard in) .
If the computer you downloaded the bios update to is connected to the internet wirelessly, you are more likely to receive a download that is not corrupted if you download it to a computer connected by a network cable.

- try the flash procedure again. If it doesn't complete after maybe a half hour or so (I don't know how long it will take - I've never flashed a bios as large as this one), the bios flash chip is probably physically damaged, probably in an area other than where the boot block code is located.

Replace the bios flash chip.

When you flash the bios on your mboard, you always do so at your own risk. The mboard manufacturer cannot guarantee it will be successful - usually it is, if you did everything right, but sometimes it isn't, because the flash chip physically failed while flashing. You are usually warned where you get bios updates on the mboard or system builder's web site that you should NOT flash the bios if your mboard is working fine. If you ARE having a problem, flashing the bios will probably NOT cure the problem, unless there is specific info in release notes for a bios update that it will cure a problem you are having, or info about previous updates that it will, since newer updates almost always include all previous fixes. If you're not sure whether the bios version supports a particular cpu you want to use or upgrade to, find out which bios version your mboard is presently using (that's often difficult or impossible to determine when no cpu is installed), and check the cpu support info for the model and - that usually tells you which bios version supports using which cpu. If in doubt, try installing the cpu anyway, if it's compatible with the mboard's cpu socket - if it doesn't work or doesn't work properly (e.g. runs slower than it should) doing that won't hurt the mboard - if it does work it may be running at the right specs and the bios may simply be giving it the wrong label.
If you are having a ram problem, 99% of the time flashing the bios will not fix the problem - either the ram is not seated properly, or it has a poor connection in it's slot(s) otherwise, both of which are easy to fix (re-seat the ram, clean it's contacts) , or, very common, you are using ram that is not listed as compatible with using it in your mboard model on the ram manufacturer's or ram distributor's web site, and it isn't actually 100% compatible.

If you have attempted to flash the bios and that failed, and you can't recover from that situation by any means you try, that situation does NOT qualify for RMAing the mboard. That said, if you're NOT honest, you could try RMAing it, others who have posted here have done that for the same situation, but you may not be successful if they actually test the mboard.

According to the diagram of the mboard in your manual, your bios flash chip is in a socket and therfore can be removed. However, look closely at the diagram in the manual and where the bios chip is on the mboard. Sometimes the actual mboard has no socket and the bios chip is soldered directly to the mboard - it saves the manufacturer a few pennies to do it that way (e.g. MSI often does that).

There are vendors on the web that can supply and ship to you a bios flash chip that is already flashed with the newest bios update the mboard manufacturer has. That's the cheaper option.

There are other vendors on the web that can supply you with a bios UPGRADE chip - it has all the possible settings and features your bios version and mboard main chipset can support, but it costs more than a chip with the latest mboard manufactuer's bios update flashed to it, and in this case your mboard is very recent and it may not be any better than the latest manufacturer's bios version, or you may not be interested in enabling all possible features and settings.

A vendor on the web that can supply and ship to you a bios flash chip that is already flashed with the newest bios update the mboard manufacturer has that I recommend is www.badflash.com - check out his web site.

He can also replace the flash chip if it's soldered directly to the mboard, only if you're in the US, but it may be cheaper for you to buy a new mboard or a used working one, because you must ship it to him and have it shipped back. It's a fiddely job not many can do.

There are other vendors that can do the same things - however, the badflash site has the most info on it about this subject of any I've encountered.

If you do have a flash chip in a socket, you must be very careful when you remove the chip. There are often circuit traces underneath the flash chip, and components next to it, that you must not damage - there may be further info about that on the badflash web site. E.g. pry a bit at a time, in several places one place at a time, probably at the corners in this case - use something with a dull tip and preferably that is wooden or plastic to pry with, and make sure you don't damage the board circuits under the chip, or the components next to the socket.
The bios chip must be installed facing the proper way - make a note of which way the printing on the actual chip surface faces relative to the socket and the mboard before you remove it, or if you forget to do that, look at the manual, or better still look at a picture of the mboard, before you install it.

I've flashed several dozen BIOS over the years & I explained how I would do it in response 7. There are other ways of doing it, but my preferred method is the "2 floppy method".

Floppy 1 = WinME boot disc
Floppy 2 = AWDFLASH.exe & M612A_18.BIN...no other files are necessary.

Simply boot off floppy 1 & select "minimal boot". When it stops at the A:\> prompt, remove floppy 1 & insert floppy 2. Then type AWDFLASH (without the .exe) & hit ENTER. Then follow the instructions.

When it asks for the BIOS file name, type in M612A_18.BIN. When it asks if you want to save the old BIOS file, press Y & name it OLDBIOS.BIN. When it asks if you want to program, press Y, then wait until the flash completes.

At most, the entire process from start to finish should take just a few minutes.

I have never come across any evidence that the boot block bios can respond to keyboard input - all I have found is you must make an autoexec.bat file with a line in it to auto run the flash program on the bios update file, on a bootable floppy.
If you know otherwise, let me know.

The boot-block BIOS only has support for the floppy drive (and minimal video support)
http://www.wimsbios.com/faq/howtore...
http://www.querycat.com/question/61...

In this case, it might also work if one copied the Abitfae.bat file included in the files in the download as well as the flash utility and the bios*.bin file to the flash floppy, and you make a line in an Autoexec.bat file:
call Abitfae.bat M612a_xx.bin
, xx being the specific BiosID number
.....

Apparently, some mboards have a jumper you must move to be able to flash using the boot block bios, but it appears that doesn't apply to this mboard.

The Award flash utility switches that were specified

/py = program flash memory
/sn = no original bios backup
(there is not enough space for it available on the floppy that also has the *.bin file you're flashing with)
/cd = clear dmi data after programming
/cp = clear pnp (escd) data after programming
/cc = clear cmos data after programming
/cks = show update binfile checksum
(the checksum the *.bin file is supposed to have may be stated where you got the download, or somewhere in the files included in the download)

The reboot switch.
I don't recommend using this, because you must be Alert and there at the computer when the computer reboots, and eject the flash floppy before it's accessed - if you eject the floppy after it's accessed you risk trashing the bios - if you miss ejecting the floppy before it's accessed you should NOT eject it - let it flash the bios again.

/r = reset system after programming
or = reboot (after programming)
.....

Found this note at:
http://www.geocities.com/sheppola/a...

Many folks will recommend that you turn of the main power switch at the power supply and move the CCMOS1 jumper to pins 2 and 3 for fifteen seconds, move the jumper back to pins 1 and 2 and turn your main power switch back on after flashing your BIOS - this clears your CMOS to factory defaults. Unless the readme file accompanying the BIOS mentions otherwise, I don't usually bother with this step because the /CD /CP /CC switches are intended to clear the CMOS data on a successful flash. If your flash fails and you need to flash from the boot block BIOS, this may be a good idea (I did it the one and only time I had a flash fail and had to recover from the boot block - my recovery was successful).

I don't know if these are universal.

I tried the same bios but from a dif country, no success.
Should I try a dif update? I think there are like 5 dif bios

It's possible, but unlikely unless it's labelled a beta version, that one bios version you are trying to load has bugs. Try the bios version that is just previous to it. If that doesn't do it, you probably will have to get yourself a replacement bios chip, or a replacement mboard - the flash chip you have has probably physically failed somewhere.

How did you prepare the bootdisk? If you load any memory management stuff in config.sys it's likely your update won't go right. You only want the system files--io.sys, msdos.sys and command.com and the bios update files.

I loaded only those 3 files that u advised. The bios files
wouldn't fit on there otherwise

I've had that problem with a bad disk. That's why when I do a bios upgrade if at all possible I load the files on the hard drive and do the upgrade from there. I don't see that that's possible in your case.

Try making the disk again. If possible just do the SYS A: from a 98 or ME machine. Sometimes it'll add drvspace.bin to the disk as a hidden file. I don't think that matters but you can delete it. Type
attrib -s -h -r a:\drvspace.bin and enter. That will remove the file attributes that prevent you from deleting it. Then type
del a:\drvspace.bin and enter. Then add the bios update files.

Like I said, I don't think it matters if drvspace.bin is there but since you're having problems try to delete it if it's there.
