how much conventional memory is it possible to have
available after installing an MSDOS virtual machine?

I'm using MSDOS 6.20 and when I do a clean boot - ie Press
F5 when it's booting, I get a largest executable size of
577k

After my normal boot, I get this up to 613K.

I know this is cheating, but it there any optimal
configuration available? How can I find out where the NIC
loads, or where the Video card loads? Any help is much
appreciated.

You can try Quarterdeck QEMM to get as mutc memory as posible in dos.
The are out of business so you have to look on the net to find it.
I don't know if it is legal to use this software.

Quarterdeck QEMM can do this for you.

In response to the QuarterDeck QEMM proposition...dont do
it, It was crap when the company was in business, and is
just older crap now. DOS can be utilized exactly like the
previous person stated. Know what you need loaded and load
it. LoadHigh anything in Autoexec.bat, and devicehigh
everything in Config.sys. First and only driver loaded low
should always be himem.sys. It is usually a little
footprint, but every driver after that, plus minimizing
files and buffers will release memory for use. Play with
the config.

If you want to see what is loading where (in the DOS memory map), type "mem
/debug |more"

In DOS, finding the optimal configuration starts with determining your
needs, and loading nothing extra. For instance, "lastdrive=E" would save
you 1680 bytes over "lastdrive=z." Most DOS rules are the same running
under VPC, but keep in mind that while you're using EMM386, VPC's Folder
Sharing feature will be unavailable.
