Solved Can't put bios dos files onto a usb bootable ms-dos stick

December 8, 2013 at 17:52:30
Specs: WINDOWS 8 AND LINUX CINNAMON DUAL BOOT, AMD C-50
(DATED SUNDAY DECEMBER 07 2013)

Hi everyone,I have a bricked ACER W500 windows based tablet...My story is a dual boot I tried with LinuxMint Cinnamon and win 8 ...after 2 weeks I got a data dump on a black background screen and now on start up there is no POST, no BIOS access ,just a black screen , no small white cursor at the top left to signal to press F2 on the auxillary keyboard to access InsydeH20 Bios, Windows Blue button on the tablet is on, the tablet's fan turns on. I spent over 8 hours combing the internet on solutions. hope this website forum helps

I made the mistake (maybe) when I installed Win 8 and did a custom new win 8 install on the ssd but didn't make a SYSTEM RESERVE of 100 MB for it for reserve files like MBR etc.(I installed win 8 first and then I did Linux)

I hooked up an external DVD optical drive and its trying to boot when I turn on the tablet and then it stops also.

Anyways , I'm trying to flash this tablet's BIOS and I know of the method for installing a BIOS via a USB bootable DOS thumb drive using RUFUS or some other program like HP USB DISC STORAGE FORMAT TOOL V2.1.8(may be more current versions) and to rename the BIOS file in the yellow DOS folder name to EAB00x64.fd as stated in this link

http://mobility.forumsee.com/a/m/s/...

I just can't or don't know how to place any Acer w500 yellow bios dos folder file contents within any of the 2 mentioned USB bootable DOs programs (there's 3 hidden files supposedly)

The Acer W500 BIOS is called BIOS v.1.14 Updates EC version found in this link as a download zip file

http://www.laptop-software.com/acer...

I'm stumped here and I tried to unhide any hidden files on my laptop wh ich has windows 7

Can anybody show me what I'm doing wrong to get these 3 DOS files within the DOS folder onto at least the easier of the 2 USB boot programs the HP DISC STORAGE FORMAT TOOL

thank you

It could be the bios chip or it could be something else. You only know it's not working. Unless you have evidence the bios on that tablet is prone to failure I wouldn't spend a lot of money replacing it, at least not yet.

If part of the bios is on the drive it's probably just the setup, like the old compaqs. In that case not having the drive installed would not leave you with a dead screen.

As far as the original attempt to upgrade using USB, did that seem to go ok? I was thinking you could test it on another computer. The update won't run until you manually type in UPDATE so you could at least see if it was booting to dos without worrying about the update running.

That doesn't sound like a bios update problem so an update may not work but this is what you need to do for a bios update from dos:

Dos has 3 system files used to boot a drive. Two are typically hidden--io.sys and msdos.sys--but don't need to be and then command.com. They're placed on the root directory, not in a folder. The io.sys file needs to be a certain place on the disk. Usually that's done with the SYS command but I suppose the rufus setup will put it in the right place. I assume you also get the dos files from rufus as they're not included with the acer bios download.

The bios download for your acer has a flasher file, an update file and a .bat file to run it.

Once you set up the flash drive to boot dos you need to copy the unzipped update files to it. Assuming that tablet has a bios setup you need to go there and set the flash drive or USB boot as the first boot device. Save and exit bios setup. Put the flash drive in and start up the tablet. It should leave you at a dos prompt. At that prompt type in update and enter. Update is the name of the bat file that runs the update. Follow any on-screen prompts. When it's done turn it off, remove the flash drive and reboot.

Thanks DAVEINCAPS for the info.Sorry for the delay in writing, I only have internet access at a library or a fast food wifi hot spot

I think your right that this is not a BIOS problem. Before my problem I formatted the mini SATA SSD into one partion then installed Windows 8 and then Linux Mint cinnamon within that and the SSD just crashed and I now think it needs formatting and a re-install of an OS with the MBR and whatever other files in the first ssd sector hence the reason maybe for that SYSTEM RESERVE of 100MB partition .I'd like to install Windows 8 RTM again in an Iso image which I have


Right now I have no Bios page showing at all on the tablet,... just a black screen so I got no access to boot set up to choose a USB bootable DOS thumb drive using RUFUS. I'll hold off re-flashing the BIOS.

In the scenario of me doing a BIOS update in the future if required this is what I did to set up my USB thumb drive to flash my tablet with the thumb drive inserted and doing the 3 button pressed tablet activation procedure (power button, Volume down and Windows Start button ) >>>

I opened up the Rufus v1.4.1.348 program and checked "create a bootable disk "MS-DOS". I clicked FORMAT OPTIONS and under ADVANCED OPTIONS checked LIST USB HARD DRIVES and found my USB thumb drive, the other lower check boxes were unchecked and I don't know if I should, these are "Add fixes for BIOSes (extra partitions,align, etc" and "Use Rufus MBR with BIOS ID (0x80 (Default)

I clicked START and my USB stick loaded and then I copy and pasted my Acer Bios 1.14 Dos files and got this in the USB stick

LOCALE (file folder)
AUTOEXEC (windows batch file)
autorun (icon)
autorun (setup Information)
COMMAND (MS-DOS application)
IO.SYS (system file)
MSDOS.SYS (system file)
EAB00x64.fd (FD file)
flas--- (Application)
Update (window Batch file)

The last 3 are from my acer bios 1.14 DOS folder with the FD file renamed . Hope I got this procedure right, correct me if I'm wrong please

Anyways I'll try to do a re-install of windows 8 on the ssd with a mini sata ssd to ssd adapter and use the interface of an external laptop SSD case to connect to my laptop

I'll use this person advice in this link ...he's #146 ,I'll contact him also and ask if I can use my iso windows 8 image instead of what he recommends a (quote) ("ssd clone image(.img) taken of a working tab w500 ssd ')

http://code.google.com/p/android-x8...

#146 boot...@gmail.com Tanner i have a solution for your iconia w500, i have had mine since it was new and have ran into this problem myself. what happens is when you format/erase the partitions on the ssd(solid state hard drive) the bios is deleted because it is partially stored on the ssd(in the bmr) and not a normal bios rom chip.

The solution is hard to find online so i will lay it out in as much detail as i can. These are the same steps needed if you wish to upgrade the internal ssd to one of higher capacity and w/r speed which i have also done with excellent results.

In the future to keep this from happening again if you repartition the ssd set the begining of the partition to start after the first 32BMs so the bios does not get corrupted/deleted from the ssd and never format the whole drive just individual partitions.

Parts: you will need to buy two hdd adapters the links below are the best prices and the exact same hardware i use.

http://www.amazon.com/Syba-mSATA-2-...

http://www.amazon.com/Drive-Adapter...

Software: you need hdd clone.

http://redobackup.org/ this is free, its a live cd you burn and then boot from a pc.

you also need a full ssd clone image(.img) taken of a working tab w500 ssd which you will restore to your msata drive.

You must open the w500 and remove the msata ssd. place the msata ssd into the adapter and then plug the adapter into the sata to usb adapter.

Plug the usb device into the computer you will use to run the clone software.
Place the .img file on another external hdd (it will be to big for most usb thumb drives)once you are setup simply boot the live cd and follow the on-screen instructions to restore a hdd image. Repeat the steps to place the msata ssd back in the iconia w500 and close up the back, if you wish to test without closing the back cover you must depress a small switch in the top left hand corner or the tab wont turn on. All done!

If you would like more help or to send it in for repairs i run a small tech repair service and would be happy to give you a good deal on fixing your tablet. You can contact me at bootdsc@gmail.com with the subject line ocean-pc.

There's no need to rename the bios upgrade file. The reason for renaming an update file is that sometimes the file name is longer than 8 characters. Dos only uses up to 8 characters for a file name and up to 3 for the extension. It's called 8.3 format. So if a file has more than that it needs to be renamed to 8.3 format. In this case the update file--wt1v114.fd--has 7 characters so it's OK. Also the UPDATE.BAT file has this line in it:

flas---.exe WT1V114.FD /s /all

which is the flasher file followed by the name of the file to be flashed plus some switches. If you change the name of the upgrade file to something else, when you run UPDATE.BAT it won't be able to find the right file. Or if you rename the upgrade file you need to edit the update.bat line and change the file name there too.

I've never used rufus to make a dos boot disk but it sounds straight forward. As long as you get the upgrade files on it it should run OK.

Hi DAVEINCAPS, well this is the current situation. I bought a mini SATA SSD to SSD card adapter (it fits into any laptop Hardrive bay or external 2.5 inch SATA case)

I installed the mini SATA SSD from my tablet and in the adapter and replaced my SATA laptop HDD with it..I booted my laptop and the mini SATA SSD does work, it showed the Linux and windows options on a black screen for what OS to boot up,in.

The Linux option works fine, when I booted to window 8 there was a glitch and Windows told me to choose a repair option like choose a recovery disc or use the built in diagnostics and it must of found some corrupt files because when it was done and rebooted the laptop was then fine with Windows 8 and all my files and functions were there

I then put back the mini SATA SSD into the Acer tablet and pressed the power button....NOTHING...just the fan intermittently turning off and on and the lower bottom WIndows Start button being lit on blue.

I tried also the bios Update using Rufus twice with your method with the original BIOS DOS folder file WT1V114.FD pasted into my USB thumb drive with the Rufus dos files....and did the tablet reboot (POWER BUTTON + VOLUME DOWN + WINDEOWS START BUTTON) and the USB stick flashed for 2 seconds and then nothing,...waited 10 plus minutes and nothing happened for the tablet.

I did the same procedure with the renamed WT1V114.FD to EAB00x64.FD...same conclusion nothing. so I think nothing was done to the original BIOS in the BIOS chip, there was no ACER POST, no BIOS screen,....I don't think the GPU is corrupted, neither the soldered RAM stick or sticks .Its a 2 GB RAM installed either on one stick or 2 which is not accessible to me from the open tablet back

So maybe the BIOS is split amongst the BIOS motherboard chip and on the mini sata ssd drive, I don't know.

I'll try formatting the mini sata ssd while installed in my laptop and load a new install of window 7 or windows 8 (not with a dual boout LinuxMint Cinnamon copy) and see if I can get that 2 partition for install (the SYSTEM RESERVE of 100 MB and the primary of abouts 32 GB for the win 7 or 8. Hopefully something will show on the tablet screen ...after all I did a complete wipe fo the mini ssd and installed win 8 and it worked fine on the tablet


worst case scenario is a motherboard malfunction,...but I've read so many others having the same scenario as me and the remedy was poiting towards the BIOS chip and or the ssd drive

IS the BIOS stored partly on a hardrive in addition to beng on the motherboard BIOS chip

Compaq used to have their bios setup on the hard drive but I don't think any computer manufacturer does it that way anymore.

Yeah, it looks like you have some hardware failure in the tablet. Nothing showing on the screen is a bad sign, especially since the bios upgrade didn't fix it.

The repair windows did when you swapped the tablet drive into the laptop was probably due to the different hardware it was seeing in the laptop. If you get the tablet going again you might have to do another repair when you put the drive back in. Windows is not very accomodating when you swap drives from one computer to another.

got a response to a forum I joined and got 2 responses #152 and #153

http://code.google.com/p/android-x8...

both said to replace the BIOS chip on the motherboard . My situation is the extreme with total black screen

I'm trying to figure out why the chip got corrupted with the dual boot set up (win 8 and Linux). Yes the boot loader with the Linux os glitched and supposedly part of the tablets bios is on the ssd and part on the motherboard bios chip

would the bios chip then get corrupted with any dual boot because its an SSD (and not a mechanical HDD) or is it a badly designed tablet motherboard
