Solved Unable to enter into bios also keyboard is not working.

August 8, 2013 at 22:23:00
Specs: Windows 8, intel Pentium 4 3ghz
I was installing windows 8 on my asus P5GC-MX/1333 MB and suddenly my UPS dropped the power supply during the installation.

And now when I restarted my pc it got stucked on motherboard logo and says to press DEL to enter into bios.
But unfortunately when I press DEL nothing happens at all because my keyboard is not detected.

I tried clearing CMOS by removing battery and also tried jumper setting to restore the bios but nothing happened at all.

Then I removed sata cable of hardisk and dvd drive and try rebooting,
This time during post it showing that keyboard not detected and F1 to run setup and F2 to loaf default setting and after that it shows a black screen and says Insert proper boot media device and press any key with a blinking cursor....

I tried changing the keyboard its PS2 but nothing happened at all.

it seems my bios has crashed and I tried to flash my bios with a usb bootable drive and during the process there comes a dos screen where I have to enter some bios command to flash the bios.But

since my keyboard is unable to detect that's why I am unable to enter the commands.

please someone help me im totally lost.Any help will be greatly appreciated.

Oh yeah,that's right, pure dos--even 98 dos--will only see files in 8.3 format.

Since you appear to have the necessary boot files we can try setting up the flash drive to run the update by itself.

I assume you downloaded the most recent update file--P5GC-MX-ASUS-1333-0413.zip--and flasher file--AFUDOS236.zip--and extracted them and copied them to the flash drive.

You need to rename the update file on the flash drive so it complies with dos 8.3 format. Your example will work fine so rename it from
P5GC-MX-ASUS-1333-0413.ROM to P5GC.ROM. (Sometimes when you rename files you unintentionally get a doiuble extension so take a good look at the renamed file and make sure it's just P5GC.ROM and not P5GC.ROM.ROM.)

Then use NOTEPAD and write in it a single line exactly as:

AFU236U /iP5GC.ROM

Save that file as AUTOEXEC.BAT on the flash drive.

So the only files on the flash drive should be the two hidden dos boot files--io.sys and msdos.sys--as well as command.com, afu236u.exe, p5gc.rom and autoexec.bat.

With that, the drive should be ready to go. Autoexec.bat will run on it's own and give the command to do the update. Now it's possible part of the update process will ask something like 'are you sure you want to do the update' which of coiurse will require a keyboard response.

If that happens shut down the computer and remove the flash drive and put it in the working computer. Run notepad again and open the autoexec.bat file on the flash drive. Edit the line from:

AFU236U /iP5GC.ROM

to:

AFU236U /iP5GC.ROM /y

Adding the /y is sometimes seen by the command as answering 'yes' to its built-in question. It may or may not work in your case but give it a try if you are asked the 'are you sure' question. If that doesn't work then we'll have to find a flasher that is compatible with the bios chip and won't pause to ask questions.

If neither a USB or PS/2 keyboard works then you're kinda screwed.

Sometimes it'll take a minute or so for an error to pop up. During that time the keyboard may be unresponsive.

When you use the jumper to clear the cmos you need to have the power cord disconnected.

Are you sure both keyboards are good?

I'm not exactly sure what you mean when you say ". . .my UPS dropped the power supply. . . " but if none of the above applies then it sounds like the motherboard or maybe some ports are damaged.

Edit Oh about the bios upgrade; it's probably not necessary but if it is a corrupted bios that's causing the problem you should be able to create an autoexec.bat file on the boot media and in it write the command calling the update file. An autoexec.bat file runs on its own so you shouldn't need any keyboard input.

I had disconnected the power chord during jumper reset.
". . .my UPS dropped the power supply. . . " means when I was installing windows 8 my power supply went off and when I tried to restart all the problems occurred.

Also all the components are okay I have checked all these with another pc.

I don't know whether a power loss may cause the bios corruption but im sure nothing else have the problem.

updating bios with autoexe.bat seems to be a good idea .if would be very helful if you could tell me some reference to do the same.

Also I heared somewhere that there is another method to do the same called "hot swap"
But I think its kinda risky since I have another p4 945 sis chipset asus mother board but im not sure that my bios is compatible with that motherboard or not..

but all I knew after looking both chips that both are 4mb bios i don't know about voltage.
please suggest me which option is best for me.should I use hot swapping method or not?

Or any alternative ideas will be greatly appreciated.
Thanks DAVEINCAPS for you quick reply.

'Hot swap' when doing a bios update is when you boot up the computer with a good bios chip and then with the PC still running you remove the bios chip and put in another one to program. The chip you swap in has to be exactly the same as the original one and obviously it has to be socketed and not soldered directly to the motherboard. I've done it once or twice and it actually works.

Post back a link to the bios update you want to install and I'll download it and take a look and see if I can set it up that way. What drive are you using to boot the bios upgrade disk? A floppy disk is probably easiest to set up but I don't know if you have a floppy drive.

@DAVEINCAPS
well both the both motherboard has socketed bios chip and both looks similar but the corrupted chip has written "winbond" on it and the right one has written "MX"
Both the motherboard is of same company I.e ASUS and both are Pentium 4.

I am not sure that corrupted BIOS chip whether compatible with that motherboard or not.

Im providing the link to the both motherboard model's page.Take a look to the system configuration or type of BIOS update and tell me what should I do further.

http://support.asus.com/download.as...

it the one motherboard which is not booting up.

http://support.asus.com/download.as...

and the above one is booting without any problem.

Also I don't have floppy drive I have to use usb disk to flash the bios .if the both are compatible to flash give me a step by step instruction to flash the corrupted chip.

The last time I was trying AFUDOS METHOD to flash the bios in the corrupted pc but not get succeeded since I was unable to type any command due to keyboard undetection.

If there is any other flashing utility that is good to deal with hot swapping don't forget to mention it.

@ OtheHill
PS/2 keyboards should be connected before the powering up and was doing the same


Thanks all for the guidance im learning much from you all.

I KNOW that PS/2 keyboards are NOT hot swappable. I didn't know if you knew that.

OK, it looks like it's fairly straightforward. You download the update file--the most recent update there is P5GC-MX/1333 0413--and the file to flash it--Afudos BIOS update tool V2.36--and unzip them both.

Then you set up a msdos disk with the system files only and add the update and flasher files. Boot with the disk and at the dos prompt type

AFU236U /iP5GC-MX-ASUS-1333-0413.ROM

and enter. I can set up a batch file to run that command but the problem is going to be to get you msdos boot files on a flash drive. Or when you previously tried to update, did you have dos boot files on the flash drive?

I can look around and see if anyone has dos image files for a flash drive. I've never had to try anything like that so am unfamiliar with it.

This was the first google link that came up:

http://www.sevenforums.com/tutorial...

It looks pretty good except the win98 dos files it has you download contain files that aren't compatible with doing a bios upgrade. You'd have to delete all the 98 files except for msdos.sys, io.sys and command.com.

You can try setting it up using hpflash1 as explained in the link above. Or if it's a problem I can just send you a flash drive I setup myself. In the long run that may be easier and quicker. I can pick up a cheap flash drive next time I go to walmart.

Oh, and we shouldn't even think about hot flashing the bios unless both motherboards are exactly the same. It either won't work or it will screw up the (possibly) corrupted bios chip even worse.

boot files on the flash drive?"

Yes I have prepared the bootable usb with the three files I was able to enter into dos .
There cursor was blinking too but the problem was to enter the command and since keyboard was not detected I couldn't be able to flash the bios.

I was following this one link to flash bios using USB drive:

www.biosflash.com/e/bios-boot-usb-stick.htm

If you can prepare a batch file to run the command then there is a hope that it can be done.
Also if you are doing so then make sure the any filename must not exceed 8 character.
for ex:
instead of iP5GC-MX-ASUS-1333-0413.ROM

just use P5GC.ROM

Thanks again DAVEINCAPS

That's a great explanation, you seems to be very clever man.

I am gonna use this one as you have explained above I have prepared all the 6 files and I learned something more about autoexe.bat as follows:

1.Gone through the motherboard manual and studied about AFUDOS FLASHING UTILITY and learned that it doesn't require any further conformation after starting flashing utility.

2.When I had booted the usb last time, It prompted dos but the selected drive was
C:\

But To run the utility I think I will have to select the usb drive first (In my case it was I:)
then I will have to put the command to start flashing utility.So,

My AUTOEXE.BAT file will be as follows:

I:
AFUDOS /iFILENAME.ROM

this script will first change the drive and then start the flashing utility .

I will try this one this time and hope it will work.

Again it doesn't matter my problem got solved or not I have learned much from you and hope I will be learning in future too.

I will respond right after testing it.

Thanks again from the bottom of my heart.

You're welcome. If you boot from the flash drive the dos prompt should show the flash drive letter. Dos doesn't recognize drives partitioned as NTFS, which your hard drive will be, so it won't assign it a drive letter. Also, it's not loading any cd/dvd drivers so those drives won't be recognized either.

Given that, it's possible that C: will be the correct dos drive letter. If you leave the I: as the first line in autoexec.bat you may get an error 'invalid drive specification' when you boot up with it but go ahead and try it. If you do get the error then just edit autoexec.bat and remove the I: line.

Finally it worked....
Thanks alot DAVEINCAPS you really made my day.After digging alot we finally done it.

When I booted my usb in dos there selected drive was c: but since I had removed hardisk and dvd drive the selected drive wad for the usb.

my autoexe.bat script was :

afudos /IP5GC.ROM

AND THIS TINNY THING SOLVED MY PROBLEM.

Started the afudos utility and flashed bios successfully.
After that it said to restart the system and then I was able to enter into bios also all hardware was detecting keyboard was working.
Its the letest bios update so there is some improvement too.After setting default for bios I successfully loaded windows 7 into it and my pc is working flawlessly.

Thanks again DAVEINCAPS from the bottom of my heart,hats off to you man.
