Thought I'd share my simple batch file to backup all GPU bios roms with one click. This is for a 7 GPU rig but could be changed to whatever you have. It is so much faster and easier than using the GUI.
cd C:\--FILE-LOCATION\ATI winflash
AtiFlash.exe -s 0 backup\backup1.rom
AtiFlash.exe -s 1 backup\backup2.rom
AtiFlash.exe -s 2 backup\backup3.rom
AtiFlash.exe -s 3 backup\backup4.rom
AtiFlash.exe -s 4 backup\backup5.rom
AtiFlash.exe -s 5 backup\backup6.rom
AtiFlash.exe -s 6 backup\backup7.rom
