I'm doing the same with a 486 server and a bunch of 386 workstations, all
IBM stuff with MCA buses, over a token-ring network, with small (~70MB-~200MB)
SCSI drives.  Basically, I made a boot disk that mounts a NFS filesystem
over the network and chroots to it. That image mounts another NFS
filesystem with all the Win95 stuff on it.  Everything pretty much works,
except the bootblock stuff (which I should get working tomorrow), and I
have yet to add the small random-number generator that will assign a
unique SMB computer name to the computer in a registry file that will be
imported on first bootup.

This all needs to be on one disk, because we all know the windows
computers will periodically have to be scratched and reinstalled, and this
is a one-time job for me, so I need to make it as easy as possible for
those who will "maintain" it. 

If all your hard drives are the same size, you could probably just
do a dd from, say, /dev/sda or /dev/hda to a file and back, and that would
copy all the partition tables and the like.

Anyway, if you need some specific help, by all means, e-mail me and I'll
see if I can help.
