Thanks in advance:

You're probably right - about 1 foot square (if you don't count the
drives :)

Yup, tried sdNg for all in N (including N) - You never know, could have
been behaving like a Dec Alpha !

Getting the JAZ drive to work is one of the steps I'm taking to help me
plunge into MacBSD development (in a tentative kinda way, if you see what
I mean. %)

Nope, I got...

   zsc0 at obio0 chip type 0
   zstty0 at zsc0 channel 0
   zstty1 at zsc0 channel 1  sheilding from LocalTalk
   fpu0 at obio0 (emulator)

and then the other stuff...

plus

   graf1 at macvid0
   changing root device to sd0a.
   PRAM time does not appear to have been read corrctly  (at least im getting
   PRAM 0x83daf80, macos_boottime; 0x32fdb2e5.            some 'normal'
errors ;)

then the fsck stuff.

Nope, no sd2.

There are no other diagnostics earlier on about nnubus. Are there any sniffer
utilities in existance that do a complete crawl of the machine's innards to see
what it's got under the bonnet [hood :] (that run under BSD) ?

I've downloaded the entire source tree last night to my PM6400, so I might
have a
look at the kernel's crawler code - but any further ideas would be good. Inci-
dentally, is there a port which works on a PowerMac 6400/200 yet ? It's got that
darn IDE, don'tcherknow.

Cheers,
