But it may be that the "wrong" kernel was booted, namely the one on the older but newly installed drive on ide1/channel B. It had once been a full boot/root/user-flesystems drive for FC3. Understand that the BIOS setup screens on this motherboard do not permit one to distinguish between multiple, internal IDE disk-drives. You can choose USB boot, CDROM boot, removable media boot, "internal hard-drive" boot; but you can't make a choice from among the latter. > Now, you can not directly tell the system to ignore the file systems > on the new drive without disabling the drive all together. Disagree. I made no new entries in /etc/fstab to mount the second, newly-installed drive's partitions. Therefore they should have been ignored. So it seems that there are only two possibilites: (1) The correct drive was booted (channel A/ide0 master) but the wrong partitions were found at mount time; or (2) The incorrect drive was booted (channel B/ide1 master) and, again, the wrong partitions were selected for mounting. Or is it possible that Grub (or the BIOS?) only want one IDE master over the whole dual-channel IDE controller? My understanding was that each channel needed its own master, and I've never had a problem before with DOS, Windo$e or linux in that situation. > Mikkel * Nick Geovanis | IT Computing Svcs | Northwestern Univ | n-geovanis@ | northwestern.edu +------------------->
