Scroll lok and page up work, and what I see is the following, copied by han=
d:

=C2=A0 =C2=A0 atapci0: <Intel ICH8M SATA300 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x1c30-0x1c3f,0x1c20,0x1x2f at
decive 31.2 on pci0
=C2=A0 =C2=A0 ata0: <ATA channel 0> on atapci0
=C2=A0 =C2=A0 ata0: [ITHREAD]
=C2=A0 =C2=A0 ata1: <ATA channel 1> on atapci0
=C2=A0 =C2=A0 ata1: [ITHREAD]

Then, at the end, I show:

=C2=A0 =C2=A0 Trying to mount root from ufs:/dev/ad0s2a
=C2=A0 =C2=A0 ROOT MOUNT ERROR:
=C2=A0 =C2=A0 If you have invalid mount options, reboot, and first thre the
following from the loader prompt:

OK - when I get home from work, I'll download and see what that does for me=
