Just to add some more detail: I think that *requiring* Ultrix in order to
bootstrap is a bad thing.

Currently, the "cat bootblocks miniroot > /dev/rz#c" method works for
almost everyone, regardless if they have Ultrix or not.
Unfortunately, it seems that the bootblocks may not work on certain models.
Can't boot (apparently):
5000/25 terry@venus.sunquest.com
5000/120 simonb@melb.cpr.itg.telecom.com.au
Can boot:
2100 dean@fsa.ca, explorer@iastate.edu
3100 hpeyerl@novatel.ca
5000/200 jonathan@DSG.Stanford.EDU
(there are other people, but I don't know what they are running)
If there is anyone that IS running NetBSD native on a 5000/25 or 5000/120
please speak up. Also, if anyone else wants to be added/removed from the
above lists, send me e-mail.
Dean.
