Expanded Memory

[Tom Ricketts]

I am still using an old version of Lotus 123 for DOS. In
Windows 98, I was able to access expanded memory in order
to open data files larger than conventional memory
allows. Is there any way to access expanded memory in a
DOS window in XP?

Thanks

Tom, there is no Dos in WinXP. It's built on NT technology.

I am not sure how your Lotus 123 for DOS determines that it has sufficient
memory. Suggest you try Windows Help and Support and enter - change pif -
in the search criteria. You will find directions on how to increase memory
for DOS programs.

May work or not.

For best DOS conventional memory, and EMM support, edit the
windows\system32\config.nt and autoexec.nt files.

In config.nt have (apart from the large number of REM lines) just
EMM = B=4000 RAM
(note the exact spaces - either side of the first = and before RAM,
none next to the second =) and

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=40
(or higher files= if needed)

and in autoexec.nt have

REM Install DPMI support
lh %SystemRoot%\system32\dosx

with other earlier lh lines REM ed out, and then any SET or PATH lines
that may already be present at the end.

This should give about 612K for a program, run from a shortcut made to
its .exe file. R-click the shortcut, Properties and on the Memory page
you can set an explicit value - rather than Auto - for any EMM or XMS
memory it may need, and for initial environment space
