Ok guys,here is the instructions on how to mod the X800 Pro to X800XT PE.
1 ) What you need is a X800 Pro VIVO with 1.6ns ram. If it's a non-VIVO,the percentage of modding it is quite....low
2 ) At least 2 floppy discs.
3 ) Download the winRAR file that i'll provide later.
Follow the steps to mod your X800 Pro VIVO to a full-fledged X800XT PE :
Floppy A
To back up your BIOS:
(a) Create a bootable floppy disc with flashrom on it by double clicking the Flasher+Floppy2.37.exe. (i'll provide the files here)
( B ) 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.
(d) Remove the floppy disc & reboot the PC.
Floppy B
To flash to the Gigabyte X800XT BIOS for enabling the 4 locked pipelines,
(a) Create a bootable floppy disc by double clicking the DrDos boot disc creator.
( B ) 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.
(d) 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
(e) Remove the floppy disc & reboot the PC.
Floppy A again,for Retail ATI XT PE
To flash to the ATI Retail X800 XT BIOS, for improved overclocking,
(a) Insert floppy disc 'A' into into the floppy drive (leaving existing files in tact).
( B ) 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.
(d) 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
(e) Remove the floppy disc & reboot the PC.
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
*Warning : Mod at your own risk!
