peart75, the HD that OSX sees is NOT on RAID, but rather connected to the blue connectors on the motherboard, which seem to me to be the bootable connectors, or at least specilly designed to accommodate bootable HDs (as when I plug the empty HD to install OSX on it to the other peripheral connectors I cannot see the HD). In order to see the empty HD I have to disconnect the Windows HDs (which are in RAID stripe) and instead just plug in the empty HD. For the installation, I have the options of (from memory, may miss a few): 10.4.8 Combo Update, Mifki, Semthex, USB 2.0 fix, 10.4.4 login window fix, ATI X1X00 AGP, ATI X1X00 PCI-E, and several others I have never installed (one to do with VIA SATA chipset, can't remember the others. Hope this helps! BTW still unable to use X1300 Pro, is someone gonna tell me how to fix this (with no access to the terminal, so would have to be via MacDrive then repair permissions via OSX installation disk) or am I gonna have to wait till Leopard or get a new graphics card?! I am new to this OSX86 business, and it's rather complicated - I don't know how to force OSX to use a certain kext for graphics driver, and I don't know how to add additional kexts (I've just copied them over in Windows, but I'd imagine I'd have to edit some files to let them know the file is there, or reset kext cache or something that I seem to remember briefly reading about). Any technical help would be much appreciated!
