OS X boots to garbled screen - ASUS PQ5 & ATI 4670
So last time I tried this stuff was back when 10.5 was a bit mature. Since 10.6 came out I decided to try this again...
I did a fresh install of OS X onto an external SATA firewire drive using my iMac and a retail OS X 10.6.0 Snow Leopard disc.
Right after the successful install I put the drive in my PC, I use the iBoot CD and select the drive. Darwin text flies by and I eventually end up at a garbled screen. Black screen with white blocks everywhere... I can't see anything.
My MacBook or iMac won't boot from the external drive - but it is a GUID drive and is OS X Journaled. The User account is not setup on the drive since when it boots I can't see anything (on the PC side)
I have an Asus P5Q Pro motherboard, 4GB of RAM. Intel Quad2Core
ATI Radeon 4670 PCI-E card (I have dual cards but have removed one for the install). Using DVI to VGA adapter makes no difference in either DVI port.
I'm using an iBoot-ATI CD via an SATA DVD-RW drive.
My internal drive is a 320GB SATA WD drive. SATA is set to AHCI.
Am I missing something? Are the steps above impossible? The BIOS is retail, I will try an updated BIOS but I think this may be a Graphics card issue? If I have a compatible .ktext Graphics Drive I can put it in or install it Manually using my iMac maybe?
Any help at all would be thankful. I know my graphics card isn't really supported but I remember last year I got 10.5.3 to run with the card, I don't need fancy features, I just need to see the screen.
I have an intel iMac for help if need be.
