Tyan gives me this wonderfully descriptive error message:

"Boot failed"

Again, I have lived with this board for 7+ months with a known problem with booting CD. I know that all of my media is good (as they work in other systems). I just am trying to not muck around inside of my machine anymore, just to start an OS install.

Anyway, I've borrowed some Mac weenie's USB floppy and am about to give that a whirl.
