Extract programs/folders to desktop

Part 2:

1. Set the bios switch to the position that is furthest away from the crossfire connector.
2. Make a backup of the card's bios with RBE to your desktop, and name it: unmodified-bios_1.rom
3. Copy the backup file to the atiwinflash folder, and name it: modified-bios_shaders_1.rom
4. Load modified-bios-shaders_1.rom into RBE
5. In RBE, selected: Additional features
6. Under Unlock 6950 -> 6970, select: 6970 shader count
7. Save the bios, in the atiwinflash directory, as: modified-bios-shaders_2.rom

Part 3:

1. I read that having UAC set to its lowest setting might be needed, your choice.
2. Click Start Button.
3. Type "cmd"
4. Right click the entry and select "Run as Administrator"
5. Black command prompt windows opens
6. Type "cd %USERPROFILE%\desktop\winflash"
7. Type "atiwinflash -unlockrom 0"

{the 0 means first adapter, if you have multiple cards, physically uninstall all but the one you want to flash}

8. Type "atiwinflash -f -p 0 modified-bios-shaders_2.rom"
9. The flash completed successfully and prompted to shutdown/reboot.
10. Shut the computer down for 30 seconds to a minute, and also flip the PSU power switch off.

Part 4:

1. Boot the computer up, run GPU-Z to check the shader count, which displays: 1536 Unified
2. Use Sapphire Trixx to modify the "Core Clock" and "Memory Clock" settings, to 880 and 1375.
3. Re-enabled UAC to its default setting.
4. Enjoy your new unlocked HD 6950 2gb
