2 x floppy discs
DrDos boot disk creator:
FlashROM 2.37 + floppy creator:
Gigabyte Flash utility & X800 XT BIOS:

Retail ATI X800 XT BIOS:

**BEFORE FLASHING THE BIOS, MAKE SURE YOU MAKE A BACKUP OF YOUR OLD ONE**
**As Always Flashing Is Risky. Do At Your Own Risk. I Shall Not Be Liable For Any Damage Cause.**
***********************************************************************************************************
To back up your BIOS: (Floppy 'A')
Create a bootable floppy disc with flashrom on it by double clicking the Flasher+Floppy2.37.exe. Restart the PC with the floppy disc inserted & boot in DOS. Once activity has ceased you will be at the A:\ prompt, type the following command line to back up your existing BIOS: flashrom -s 0 backup.bin
You now have a file on the floppy disc named
'backup.bin' this is your original BIOS which you may require at a later date.
Remove the floppy disc & reboot the PC.
***********************************************************************************************************
To flash to the Gigabyte X800XT BIOS for enabling the 4 locked pipelines (Floppy 'B')
Create a bootable floppy disc by double clicking the DrDos boot disc creator. Unzip the Gigabyte Flash utility & X800 XT BIOS, then place the files on the floppy disc. Restart the PC with the floppy disc inserted & boot in DOS. Once activity has ceased you will be at the A:\ prompt, type the following command line to flash the BIOS:
GVF11 -p -f A:\r80x256v.f1
Remove the floppy disc & reboot the PC.
***********************************************************************************************************
To flash to the ATI Retail X800 XT BIOS, for improved over clock (Floppy 'A')
Insert floppy disc 'A' into into the floppy drive (leaving existing files in tact). Place the downloaded Retail ATI X800 XT BIOS ( X800XT.bin ) on to the floppy. Restart the PC with the floppy disc inserted & boot in DOS. Once activity has ceased you will be at the A:\ prompt, type the following command line to flash the BIOS:
flashrom -p -f 0 X800XT.bin
Remove the floppy disc & reboot the PC.
**********************************************************************************************************
I recommend you retain the 2 floppy discs for future use.
If you have followed the instructions carefully you should have a fully fledged ATI Radeon X800 XT 520mhz core / 560mhz memory.
Due to the heat generated by the additional 4 pipelines your maximum core over clock is likely to be reduced by on average 20mhz.
Thats All! :hap2:
