I gathered that much.... but my main question was "is this a problem" ?
And is this b/c of running on only 8 meg of RAM ?
(my machine got hung yesterday while compiling a new kernel, and
the only thing that showed on the console was a stream of these
lines).
|(SPARC-BSD is much happier with at least 16 MB.)
Well... when scrapping for hardware, thats the best I could drag up. SiGH.

|Odd. Those should be in <machine/instr.h>. If the copy on the

|making the tape---this may have been fixed by the pmap.c patch,
|although I have no way to test it myself), the FTPable version on

They are defined there, but that file is only pulled in if DIAGNOSTIC
is defined..... and I was attempting a compile w/o DIAGNOSTIC defined.

|No.
That also answers the above question. Thanks.

|You have to use SunOS to format and label it, yes. (That code has
|changed quite a bit since the 4.4BSD release, but as I recall, the
|release version did not support BSD labels at all.)
Ok, so are you saying the 'post-4.4BSD' version supports BSD labels ?
Are there any interesting changes for the SPARC that have happened
since the 4.4 release that I could/should use, and how do I get them ?
Yes, I'm aiming at getting a bsd4.4 sparc up, then being able to use THAT
to bootstrap/setup addition sparcs (w/o going back to SunOS). With what
you have said, that is currently impossible.
Thanks for your help !!!
