cool. finally got the 4/330's original cpu to behave. trick seems to be
to turn it off, then turn it on very soon after. I guess this means a dead
nvram battery and thats' not long enough for it to "forget" the defaults
it gets told the first time around?

this one has 4.1.1 - but doesn't respond to "help", so i guess this was
one of the roms they ran out of space in?

the other 4/300 cpu has 3.0.1 (i think) and does respond to "help" - but
96megs takes /ages/ to test in diag mode.

yes.. my other problem seems to be a dead disk. booting from its internal
disk it stops with bus errors.

hooking up other disks it halts with "illegal instruction" on disks which
probably aren't bootable, and on another starts to boot before getting a
watchdog reset.

i'm (purely) guessing that in the latter case it's trying to boot
something which isnt designed to boot on a sun4. the disk in question is
from an old IPC - and some of these had solaris 2.5 on them. i'll have to
pop it back into an ipc to check.

is this why there are references to dead chickens with these, or does it
get worse than this? ;)

<time passes>

okay, borrowing a cd-rom from an SS5, and taken it down to 8Mb for now, it
seems to like it...

I'm much happier now ;)

I assume, then, that device->scsid mappings are different for the
sr() form?
