I never used any of the 2.X branch, and I know some of the docs lurking still refer to that stuff, but SCSI disks are named daX now. If your root partition is on the first SCSI disk, change that line to 'config kernel root on da0'. As an aside, if you have SCSI and IDE disks, you may have problems booting off the SCSI drives. I booted for a month off of the fixit disk because I was getting a 'panic: cannot mount root'. As it turned out, it always tried to change the root device to my second SCSI disk for some unknown reason. I finally found the solution in the mailing list archives. Edit your /boot/loader.rc file and add the following lines: set num_ide_disks=1 (if you have one disk) set root_device_unit=1 Somone else had this problem just a day or so ago. I'm not sure if you need both but I haven't had any problems with using both of them. Where would be an appropriate place to put this in the docs? I'd be happy to submit something about it. > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Parker Brown > Sent: Saturday, June 26, 1999 3:50 PM > To: Tech Support > Subject: Rebuilding Kernel, Probs defining root device > > > Rebuilding the kernel on 3.2, and I'm having trouble defining where to > locate the kernel in the statement: > > config kernel root on wd0 > > This is the first time I've tried to rebuild the kernel on a SCSI > machine.
