The computer was "primed" by booting OS9 and starting System Disk and hitting save so it can boot ide drives.
This issue renders 10.1 unbootable and 10.0 has similar issues when the installation completes
>How-To-Repeat:
Install NetBSD 10.1 on a G3 Mac with OF 2.01f and try to boot it.

Try "setenv real-base ffffffff" (i.e. the default value) instead.

Hi There
To start I would like thank you for your quick response, apologies for
the delay in response. I went down a rabbithole trying to install 10.0
but that didn't work (it would boot but get a dsa trap)
I tried the values you suggested and no luck and I tried some values
from the linked post and got a little further but no luck as yet:
--- Fresh Boot after time set and Sysem Disk save
--- real-base at default (-1)

I tried some more values, 9F00000 didn't work but FF00000 did work. I
increased this value arbitrarily so FF00000 is probably larger than is
needed. I missed the logs for these but 9F00000 was basically the
same.
--- First SSH to Mac G3 Running NetBSD 10.1

Trying other values I got the same issues incrementing the first digit
of real-base from 9 though C, at D open firmware stopped starting (no
chime) and so I reset the nvram by removing the battery and power at
which point I went through the time and system disk process and tried
real-base FF00000 and the default load base and that seems to work.
An issue I have encountered is that it really doesn't like having
384MB memory, I had to remove a stick and bring it down to 256M to
get it to boot.
I;m not really sure what load-base and real-base do, although its
seems to have relevance as some kind of memory addresses for the
kernel/userspace loading.
I hope this information is useful, I have it booting but I am not sure
why the memory limit.
Thanks Again
