Yeah, I actually did that before I received this email, but after I asked the original question. It works fine, as expected. Now, of course, I'm left wondering *why* is this the case? I truly made *no* BIOS changes. I had beed using boot=/dev/sda for over a year with no problems at all. It's just when I added a new network card that this happened. I suppose it's more a mater of curiosity at this point than anything else, since boot=/dev/hda works. It's still very weird, though. noah ___ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html -BEGIN PGP SIGNATURE- Version: PGPfreeware 5.0i for non-commercial use Charset: noconv iQCVAwUBObrFjodCcpBjGWoFAQFiPgP/erWWw4qdf2dnSYLzFIVEA56c5s+roR8O dAJbHZ5TIa82kbIgpWoL++Bm400ObPL7sEHX/RMMyT6OA8e6ZXpXLApU3kee64CN QZH9Zj9gnI9AWOPZv/7iCs7qvPYqHQV4MAY9XUsY6GRqd111XLe4WMWSHjLOY2Ys JhTMucIjPxE= =i4HR -END PGP SIGNATURE-

The BIOS (which LILO uses to load the kernel) numbers disks as 0x80 for the first drive and 0x81 for the second. The catch with a mixed scsi/ide setup is that the "SCSI BIOS" inserts itself into the call chain and fondles those numbers (usually) so that the SCSI drive is the first drive from the BIOS perspective, even if Linux can't see it. So you have to convince LILO of two things: 1) it should write the boot loader to the SCSI drive 2) it should ask the BIOS to load from device 0x80 (which should be the scsi drive). You do this in lilo.conf: disk = /dev/sda bios = 0x80 -- Brian Moore | Of course vi is God's editor.
