Richard, thanks for you thoughts.
I do have SCSI for the boot order in the bios. That's how and why it's been
booting for years, with the sata drive unplugged. This mobo is probably 3
years old - dual Socket 370 Pentium-III, before the time sata became popular
so it's not sata aware, but it shouldn't matter.
I'm really stumped on what the problem is. I shouldn't even need any linux
sata drivers since I'm not booting from the sata drive. I bought it because
I want the extra space so yea I'll need the sata drivers in order to use it
but it shouldn't prevent the system from booting off scsi. But like I said
sata drives are treated as /dev/sdX so maybe at some early point in the
booting it thinks the sata drive is /dev/sda when it's not.
I'm leaning towards ether tweaking something in lilo (don't know what
though) or the promise bios that gets loaded when the sata drive is plugged
in is interferring somehow.
What really puzzles me is that it doesn't always hang at the same point
during "loading linux ..." and it actually booted up once.Almost as if
something timed out and proceeded.
