mount 'target disk mode' Macbook as 1394 disk

[brook%biology.nmsu.edu@localhost (Brook Milligan)]

I am trying to recover the disk drive on a Macbook by booting it into
'target disk mode' (which is supposed to emulate a firewire disk) and
mounting it on a NetBSD box.  The relevant kernel output follows
below.  This particular case comes from connecting a known good Mac
(in target disk mode) to the NetBSD box.  Thus, the 'not ready' errors
may not be related to any internal disk problems (the disk works fine
in this Mac), but rather to the firewire connection.  This was
supposed to be my positive control to demonstrate how to manage the
connection, but it doesn't work.

In case it helps, I also included a dump of the configuration ROMs for
both the NetBSD box and the Mac.

Does anyone have experience with working with firewire disks on NetBSD
and specifically with connecting to a Mac in this way?

Thanks alot for your help.

Cheers,
Brook
