I got a
Cannot find PCI.SYS error trying your disk patch
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional 2tb+ Extended" /kernel=krnldsk.exe /hal=hal64g.dll /fastdetect /PAE /noexecute=alwaysoff
I was using the 64gig patched HAL though, I'll try without it.
EDIT:
Tried normal HAL.DLL, still got the PCI.SYS error
