OK...Let me throw a curve...

Vista came pre-installed on my machine on a SATA drive.
I added a ATA drive to store my music, and this appears BEFORE the SATA in the BIOS.
My OS X drive is ATA also, the music drive became the slave.

If I boot off the Vista drive, I have no problems.

If I boot to the OS X drive, I get Chameleon 2 Bootloader. If I select Vista, its fine. If I boot to OS X regular, I get a black screen. OS X verbose, I get a TON of text that flys buy too fast to read, then a black screen.

If I boot to OS X iPC Live, then rd=disk1s1, its fine, and right now, this is the ONLY way I can boot into OS X.
