I've patched the Sapphire 7750 LP to support UEFI booting. This will give faster boot times into Windows 8 and will eliminate any "OptionRom" errors the the motherboard's UEFI might throw. It'll also give you proper resolution support in Clover if the CSM video driver is causing crashes. I've tested it and it works fine in my G4 Cube along side the onboard HD4000.
To install.
- Back up your current vbios if you haven't already done so.
- Create a DOS boot drive. There are plenty of tutorials online for this.
- Copy contents of zip onto the drive
- Boot from the drive (enable legacy boot first)
- run "atiflash -p 0 7750UEFI.rom" without quotes
- It should run through and tell you to restart if successful.
That's it. Please don't try this on other brand cards even if the model number matches. If you do, do it at your own risk. I've only tested this on the Sapphire LP version.
