Flashing GPU BIOS for Ati cards

you need someway of booting into dos. i already have a utility cd called "ultimatebootcd" which allows me to do this. i have a small fat32 partition on my hard drive which i use to store atiflash/bios files. another method is to use a usb key/floppy disk and make it bootable - you'll have to wait for someone else to offer advice on that - i don't know how. :o

i use atiflash - the latest version is here.......

first backup your original bios using this command

atiflash -s 0 backup.rom

to flash a new bios, run this command

atiflash -p 0 new.rom

(that's the number zero in both commands. change new.rom to whatever your new bios file is called - it might be worth checking the filename is less than 8 characters in windows first to get around the limitations of dos)

DISCLAIMER: flash your bios at your own risk. don't blame me if you bork your card. :D
 
Winflash has worked perfectly for me every time for about a couple of dozen flashes. A lot easier to use with its gui as well.

Make sure you close every program possible including CCC before using it. You want nothing to interfere.

Remember that it can take a while. Everything freezes for a while, so remember that it hasnt crashed. In the latest build it says a progress bar's been added which should help.

Click to expand...

Are you talking about this? http://www.ultimatebootcd.com/

If yes then do you use MS DOS? It says its not included in the disc due to its commercial nature...

I have tried Winflash but it failed for some reason, thank god my card is fine.

Whats the procedur to use with the bootcd? Do i need a FAT32 partition for that to work or is NTFS good enough?
