Thanks, all, for the replies...

First, I'm not installing on another PC because I only have one client
(now fairly inactive) that runs SCO, and it is not cost justified. 
Worst case is that I'll keep my old dual P200 PC to support them.  I
just thought it'd be easier and more convenient if I could run both
linux & sco at the same time on my new p4 1.7GHz box...

Info on bochs:  It's a Pentium emulator, similar to VMWare in that it
allows you to install guest OS's on linux.  It's home page is
http://bochs.sourceforge.net.  BTW, it's pronounced like the English
word "box".  Plex86 is another VM, if anyone's interested
(http://www.plex86.org).  Both are still "young", but there are people
using both.  (There's a lot of "cross development" between them, too.)
 And both are Open Source (free).  Also, linux-abi is "native linux"
support for running SCO binaries.  It works with some of the programs
that I *must* run, but not all (seg faults).  That's why I'm trying
bochs (and plex86, and wine [for windoze pgms, www.winehq.org]; I gave
up on VMWare because they say they have no plans on supporting OSR5).

I'll check out the VMWare thread.  Could provide useful info, even if
it is not directly related to Int13/FAh.  Thanks for the pointer...

As far as other issues trying to run OSR5 on bochs, I've got a hacked
bios that gets around initial boot problems, but the kernel
initialization causes it to crash at F dptrinit (I once made it to F
fdi_init).  I know I've run across the list describing these
initialization steps, but can't put my finger on it.  Can anyone point
me to it?

Bela, thanks for the info on the LAN boot proms.  Do you mind if I
copy your response (with credit, of course) into the bochs bug report
that I initiated on the bochs site?  I'm sure it would be helpful to
their development.

If people are interested, I could keep this newsgroup updated on my
attempts to get OSR5 running on Linux.  Let me know.

Thanks again,

Carl
