Sounds like this problem is a good old dos problem, not really
sys(pxe)linux problem really.  You need more conventional memory freed
up, but, require the usage of certain drivers.  Show us your
config.sys and autoexec.bat files and perhaps we can at least try to
come up with something that clears up a tad more conventional memory.
I'd say start off by putting himem.sys on that disk if it's not
already and loading it with a DEVICE=HIMEM.SYS statement in
config.sys, then loading that network driver or whatever with LH (eg
LH NETWORK.COM or whatever.)  If you don't already have one, place a
DOS=HIGH,UMB in your config.sys as well.  Personally, I've worked with
DOS for a while, and only network drivers and sound drivers were ever
a problem, but, I still usually ended up with around 590K free memory,
which fits some of the toughest requirements out there.  Beyond that,
just show us what you need and maybe something can be worked out.  Oh,
and if you can find a copy of mem.com from some DOS utilities
somewhere, toss that onto the disk.  It makes it a lot easier to
figure out what is causing the biggest problems.
