So, here's the parts ...
nVidia 8800GT video
Asus A5NE-SLI; Core2 Duo Quad processor
2 Gig RAM DDR2 loaded (2 more on desk)
I have a separate HDD, 320 Gig with Snow Leopard and Chameleon loaded. I attempt to boot, and I get the chameleon splash screen, and the Apple with the whirly-gig - then the 'Null' (Circle with a diagnal bar through it) appear on the Apple icon.
Doing the verbose, I see that there is a USB error, then Null Pointer on Stack, and an indefinite 'Waiting on Host'.
Since I have no Mac in the house - I'm kind of stuck.
Suggestions are welcome, and sincerely appreciated.
