"Not enough memory"....

I have a buddy who installed VPC2004, and installed DOS 6.22...
And when he tried to load an APL language system, he got the
"not enough memory" error. He has it set for 128 Meg.

Well, I'll grant that it isn't exactly the same thing,
but I have that APL system running under 98 in my VPC2004
with 420 M......and when I drop the memory to 125 M,
everything still runs fine.

Any advice I can pass along to him? He needs 6.22 because he has
some old DOS software that won't run anywhere else.

Thanks

The 'not enough memory' in a VPC DOS guest can be very tricky, and often
can't be resolved.

Often the DosBox (http://www.dosbox.com/) will run such programs without
problems, otherwise you have to play with loading in upper memory etc.

I don't think that MSDOS 6.22 could handle 128 Mb RAM. At that time
all you had was 1 Mb RAM, which was divided into 640 kb for the
operating system and the remainder for system devices.
He should drop RAM way below 128Mb for this guest, prbably to 8 Mb or
so and then try an EMS handler to make use of that memory from MSDOS.
Can be tricky.

In Win98 those details were handled by Windows and a DOS window only
got what it needed from the available RAM to Win98.

Thank you for the great link, Benjamin. I have
passed it along to the fellow who has the prob.

I also suggested to him that the capability of
98 to run old DOS programs perhaps without all the
manipulation of memory is worth considering, and
he has ordered a 98 to try out.
