So, I followed Skull Fire's instructions very carefully. Made a live image of aptosid ponos and used it to create the single partition. Made slices per his instructions, too. No joy. Install goes fine, but the BTX loader stops just after it says
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
(1) The system video and keyboard (not the mouse) is on a KVM switch. Do you think that would make any difference?
(2) There is a second, small (and old) 1.22GB Quantum Fireball on SCSI ID=1 in addition to the (brand new, just out of the box) 33.9GB Quantum Atlas III on SCSI ID=0 on the bus. The smaller drive also has a single BSD partition, and my plan was to use it as SWAP. Do you think this second drive on the SCSI bus could make a difference? I could, of course, just disconnect it.
The strangest thing about this is that, once the install completes, not only will the system fail to boot to the HD, it won't boot to the install DVD anymore, either. It will, however, boot to the live aptosid CD that I created last night.
I'm completely stumped. Help?
