Hmmm, I thought wd0 and wd1 were the master and slave drives on the primary IDE port (wdc0), and wd2 and wd3 the master and slave on the secondary IDE port (wdc1). Before the system boots, when the boot: prompt appears, the default does seem to be wd(1,a), which works, well it finds /kernel anyway. If wd1 is in fact the second HD as you state, how come 'mount /dev/wd2s1 /mnt' works, but 'mount /dev/wd1s1 /mnt' fails? I have tried the generic kernel as well, which should automatically try to find the root partition on the boot device. This fails also with the same 'cannot mount root' message. Maybe I should move the secondary master to the primary slave, leaving the secondary IDE port just for my CDROM. I would post the output from dmesg if I could, but I need to make it boot properly to do that. ;-) Thanks for the reply, Jeff. >On Mon, Jan 26, 1998 at 10:23:29PM -0000, Bond, Jeffery wrote: >> Hello, >> >> I have installed FreeBSD 2.2.2 on a partition on my PC.
