Hi,

If you want to be able to boot from the hard drive you need to create
a small bootstrap partition to host the `ofwboot.xcf' file.
That partition need to be on a file system that OpenFirmware
understands; such as HFS, HFS+, etc (not FFS).

If you have Mac OS installed, you can use the Mac OS partition.

Once you have created this partition, you`ll have a partition map like this:

# pdisk /dev/wd0c
Edit /dev/wd0c -
Command (? for help): p

Partition map (with 512 byte blocks) on '/dev/wd0c'
 #:                type name     length   base     ( size )
 1: Apple_partition_map Apple        63 @ 1
 2:           Apple_HFS boot     262144 @ 64       (128.0M)
 3:     Apple_UNIX_SVR2 root    4194304 @ 262208   (  2.0G) S0 RUFS k0  /
[...]

In this example the boot partition is number 2 and the root partiton
is number 3.

Then the OF command used should be like this one:

0> boot hd:2,\ofwboot.xcf hd:3,/netbsd

Notice that "/netbsd" is the path to the kernel image you want to boot.
