Some more followup...

Well, getting the network "card" going wasn't all that bad!  What I
did:
- I needed to re-compile bochs with networking implemented (ran
./configure --enable-ne2000)
- Added the "ne2k:" line to the bochs config file, as suggested in
that file's comments (for linux), except that I used IRQ10 instead of
9 (9 wasn't listed as being available in "scoadmin network"...)
- Used scoadmin to configure a Novell NE2000 card and TCP/IP
- bochs uses "raw" network card access, so I had to "setuid root" for
the bochs executable.  (I don't like this, but until I can find out
how to get [as a regular user] CAP_NET_RAW capability, I guess I'm
stuck...)

It seemed to work as soon as I rebooted the new kernel!  I was even
able to telnet to my old SCO box, as well as ftp some files from it. 
I did have bochs panic once during an ftp transfer, but after
restarting bochs and trying the file transfer again, it went OK.  I
guess I won't be able to debug that one <grin>...

Everything else seems to be running quite smoothly, so far, except for
the clock.  Bochs seemed quite slow with the very high emulated IPS
value, so for the time being, I'm living with the fast clock
[periodically resetting it back to "real time"].  Bela, can you give
me any insights as to how OSR5 gets the time?  The emulated clock
speed seems to be dependant on what is going on with OSR5, so even
setting an IPS to any one value is not going to totally solve this
issue.  This may be another thing that I'll have to fix...

Oh, yeah, I get a very occasional wd0 timeout, but I think I can live
with that (at least for now).  And I have not figured out how to
switch between multiscreens within bochs.  Is this configurable within
OSR5?

Other than that, I'm pleasantly surprised with how well bochs is
handling OSR5.

Printing, I think, will be my next hurdle.  (Bochs directs the output
to a file, so unless I can write a pipe to split it into print jobs,
this might be tough!)

I'll keep you informed on my progress.

Carl

P.S., The three patches that I posted on the bochs bug tracker are now
part of the patches directory within the CVS tree.  Hopefully, they
will become a permanent part of bochs in the not-too-distant future!
