Answer to Paulos7 in topic 1437:
''Through all this, I considered CSM options, but my motherboard only has "Enabled" and "Disabled". I tried it "Disabled", but quickly discovered my 560Ti can not be flashed with a GOP capable VBIOS (it's pre-600 series). And I don't know if it's possible to "upgrade" CSM modules from a newer series of ASRock motherboard (I doubt it), or if the added CSM options would even be useful in my case''
Windows 7 installation with UEFI mode: CSM Enabled even if Graphics card has Gop Bios
