Oops. Yes.  Sorry.  By the time you get to the loader prompt, the
kernel has already been loaded.  You can just type:

    boot -s 

at that point.  Doing the unload then the full boot path thing is a
long winded way of achieving the same effect.

Hmmm... Clarify for me: which disk is it exactly that your FreeBSD
installation is on?  ie. what does 'lsdev' return at the boot loader
prompt?  If you're using a GENERIC kernel, or your kernel config contains

    options  ATA_STATIC_ID

then the disks are numbered like this:

    ad0      Master on the 1st IDE bus
    ad1      Slave  on the 1st IDE bus

    ad2      Master on the 2nd IDE bus
    ad3      Slave  on the 2nd IDE bus

If you haven't got that option in your kernel, then the disks present
in your system just get numbered in order.
