v6.0.1 worked for me in the past, but I was trying to mount an EFI GPT HFS+ Mac partition on a SATA drive, and it wasn't working. I downloaded v6.4.3 in hopes it had support for GPT and burned that to a CD, but now it just goes to a blank screen no matter what I try. It acts like things are loading, and even after the activity LED on my computer case stops blinking, pressing the Reset button will cause some more activity, followed by a the CD being ejected after I press Enter, even though I can't see a thing on the screen.

I tried: knoppix vga=0, knoppix vga=0 debug -b 3, and failsafe debug -b 3 but they all more or less immediately go to a blank screen.

Hardware is:
Abit KN9 SLI nForce 570 SLI
Athlon X2 4200+ 2.2Ghz (Socket AM2)
3GB DDR2 (2x 1GB + 2x 512MB)
Asus GeForce 7600GS 512MB DDR2 (PCI Express)
250GB 7200rpm Hitachi SATA drive
52x CD-ROM (IDE)

no floppy, no DVD or burner on this computer.

Using PS/2 keyboard, Microsoft USB Laser Mouse 6000, and a Samsung SyncMaster 940BF 19" LCD. I normally only have DVI hooked up, but as the video card has a VGA output as well, I tried that just to check. Still blank screen there.
