Also, it has been said that the typical > Toshiba SCSI CDROM should have no problem being recognized. Your BIOS starts up and reads the bootstrap code off the SCSI CDROM. Now the bootstrap takes over. The boot code on the CD assumes that it is running on a IDE CDROM. So it goes to look for the kernel on the IDE CDROM and... well, there is no kernel there. You can try entering the proper location at the boot prompt (something like, 1:sd(0,1,a)), but I am not sure if SCSI CDROMs are supported for booting. > I also attempted a CD boot on another machine with a cheesy, but > compatible, IDE CDROM, and it too failed -- however, it didn't get quite > so far. A lot of people have trouble when the IDE CDROM is on a secondary controller or if it is a slave with no master. And just for completeness, the CDROM is listed as a boot device in the BIOS? > Does this mean there's a problem with the boot sector on the Walnut Creek > 3.1-RELEASE CD?
