Memory available to DOS...

Is there any way to increase the amount of memory
available at a DOS prompt?

Here's what I'm dealing with:

C:\>mem

655360 bytes total conventional memory
655360 bytes available to MS-DOS
525528 largest executable program size

1048576 bytes total contiguous extended memory
947250 bytes available contiguous extended memory
941056 bytes available XMS memory
MS-DOS resident in High Memory Area

C:\>

The machine has 1GB of RAM.
I have an old DOS-based application that NEEDS at least
620124 bytes available to MS-DOS in order to even run.
I've tried using the shell command in the config.nt file
and even tried manually shelling out to DOS with the /e
and the /p commands, but to no avail.

Is there something I'm missing?

Thanx.

Run mem /c
and see what's loaded. Possibly un-needed items like
MSCDEXNT
REDIR
Although I do not know what the absolute maximum low memory size
attainable is.
