Gigabyte GA686BX M/B corrupt Bios

[Scotia]

Help.....

I have corrupted my Bios on my Gigabyte Motherboard and now I have no display. Is there a way to recover it?? I don't know if there is a recovery jumper and I've heard you may be able to do it with an ISA Video card which I don't have....

Tell me about what you did to corrupt your bios flash, how did it happen, how did you go about it ect. Just relate to me everything you did from the start. Tell me what bios version you used for your board, was it the correct bios file?..how do you know it was the correct one?..what flasher did you use ect. What settings did you do in your working bios before the flash attempt. What version Gigabyte board do you have.

Tell me how you made a boot disk. I need to "see" thru your eyes everything you did to try to setup a possible recovery.

Sorry to ask so much, but I need to be where you were to get a feel for exactly what happened to proceed.

I used the wrong flash file for this and it told e it was the wrong one but it hung my PC up so the only option was to power off and on.... the wrong thing to do but the only option I had..... it's a Gigabyte GA686BX motherboars with AMIBIOS...

I went to Gigabyte's web site and did not find a GA686BX listed. Can you find your board at the site? What processor does it use, and what clasification is it, AMD socket A, slot A ect? Intel?..Can you find the right bios file for your board?...did you try to save your old bios during the flash attempt?

At this point we need the correct bios file to flash to, either a new upgrade, or an older one. Did you write down the bios string before you started the flash? if so, what was it?...

It is on the Gigabyte Website. It is a Slot 1 Processor, the Bios wasn`t saved before I flashed it. and I do have the correct one to flash it now. The thing is I just don't know how to recover it.

Ok...tell me exactly the name of the flasher and the name of the bios file.

Like maybe AMIflash.exe and biosname.rom...or whatever it is. Just be sure to give me the correct names of those two files, and we will go from there...

Also, go to www.bootdisk.com and download the following boot disk:

DrDOS 7.X Disk For Bios Flashing Basic-No Drivers

It is on the main front page at the site. Put a formatted floppy disk in your A:\ drive and double click the file you download, which is an executable (.EXE) and it will extract all of the necessary files right to the floppy disk. After you get this boot disk setup, I will tell you how to proceed from there.

I am now in a position to go ahead. I have the startup disk and the Bios file and Flasher the .exe is flash848.exe and the file is 6bx.F2a now how do we recover.

I presume you have downloaded that boot disk I asked you to do, and you now have a boot disk made up and ready to go.

If so, then do this. Go to Windows Explorer, and with that boot disk in the A:\ drive, click on the A:\ drive. You will see 4 files, command.com and two IBM files and an autoexec.bat file.

I want you to edit the autoexec.bat file with note pad. If you will, highlight the file autoexec.bat, and from FILE up on the tool bar, choose 'open with'. This will give you a menu screen to choose which program to open the file with...choose NotePad.

Once you have opened the autoexec.bat file with note pad, you will see two entries: Echo off, and cls.

Do the following by copying and pasting the following right under cls:

Echo off
cls
flash848.exe 6bx.f2a /py /sn /cc /cp /cd /sb /r

When you have that line in the autoexec.bat file, click on file and click on save.

Close the autoexec.bat file, and do it again by the same means...look in the autoexec.bat file to be sure the statement,

flash848.exe 6bx.f2a /py /sy /cc /cp /cd /sb /r

was saved. If it was, take this disk, put it in the A:\ drive and turn the machine on. If the bootblock in your bios did not get over written, this should reflash the bios and reboot itself. Watch for the A: drive LED co come on, indicating that it has found the drive and is reading the diskette. If all goes well, this should reflash the bios and then reboot...remove the diskette if rebooting starts.

It is very important that that command line I typed up for you has the proper spaces ect, so if you can, just copy and paste what I typed into the autoexec.bat file.

Then go into the bios, and from the main menu, load bios defaults, save and exit. go back into the bios and make the necessary changes and redetecting the hard drive ect.

Good luck!!
