Neither of these works for me. In both cases I get the following =
output:
load-size=3D0 adler32=3D1
LOAD-SIZE is too small

I can boot via the graphical boot disk chooser (hold down Option key =
when powering on, then select external FW drive with FreeBSD installed). =
These are the drive partitions I see when booted into FreeBSD:

The ad0 drive is the internal drive, on which Mac OS X is installed. =
The external FW drive is da0. The FreeBSD root partition is on =
partition 2 in the output above.
Do the OpenFirmware partition numbers match the corresponding ones in =
the gpart output, or are they one less? (Or, do they match the slice =
numbers, which appear to be one greater?)
FWIW, when I boot from the graphical chooser, the "Boot volume" is =
printed during boot as =
/pci@f4000000/firewire@e/node@0010b9f700fc75e4/sbp-2@c000/disk@0:3
Any clues as to why booting from the OpenFirmware prompt is not working?
Cheers,
Paul.
