Ha! This seems to assume that the (fdisk) DOS partition
is the 'i' partition in the disklabel - it is not;
I created a [c]ustom disklabel.
When in the install sequence is this copy of ofwboot done?
Even my real wd0i partition, which is /usr/xobj
(untouched since install) does not contain ofwboot.
That leads me to speculate that this ofwboot copy
is performed _before_ the installing user edits
the disklabel; but perhaps at that moment,
wd0i _is_ really the DOS partiton, and later
I can make the disklabel what I want?
Or did I miss it somewhere in the macppc install documentation
to leave 'i' alone so that ofwboot gets copied to the right place?
Anyway, I tried getting to that copy ofwboot now, as follows:
I enlarged the disklabel-maintained area to the whole disk ('b')
and created a partion for the DOS piece of the disk. Looking at
Disk: wd0 geometry: 155061/16/63 [156301488 Sectors]
Offset: 0 Signature: 0xAA55
Starting Ending LBA Info:
#: id C H S - C H S [ start: size ]

*0: 06 0 0 2 - 2 0 33 [ 1: 2048 ] DOS > 32MB

I made the DOS partition start at 512 (and then 1024
and then everything under 4096 wherethe obsd part starts),
but never could I mount that DOS partition ...
I will reinstall again, leaving the [a]uto disklabel untouched.
