I'm obviously missing something fairly major here, can anyone enlighten me. Have 3 scsi discs id0 quantum (Win95) id1 dec (FreeBSD root/usr/var) id2 dec (FreeBSD src/home) Booteasy installed on id0 and id1. Occasionally I'll remove the quantum, which causes the dynamic sdN allocation. to change (dec drives become sd0 and sd1) which causes fsck(fstab) problems. So, I decided I'd fix down the scsi id's config kernel root on sd0 disk sd0 at scbus0 target 1 disc sd1 at scbus0 target 2 I _thought_ this would do the trick. Works OK if the Quantum is removed/powered off. If I add the Quantum back in ... System boots with the Quantum in place, assigns id0 to sd2, id1 to sd0 and id2 to sd1. Then it sets root device to *sd1* and barfs trying to mount root as sd1a. Seems to be getting sd1 from the fact that I'm booting off id1. So, I switched tack a little config kernel root on sd1 disk sd1 at scbus0 target 1 disc sd2 at scbus0 target 2 System boots with the Quantum in place, assigns id0 to sd3, id1 to sd1 and id2 to sd2. Works. If I remove the Quantum, system boots, assigns id1 to sd1, id2 to sd2, get the same problem, tries to mount root off *sd0*. I'm getting the feeling that the root disc assignment is being affected by the bios' C: D: scsi assignment, and that my 'config kernel root on XXX' line is being ignored. Anyone have any ideas on what I am missing ? tony
