Basically I just want to make sure that it's there. The MSDOS port of
the MAME emulator among others will make pretty good use of it.
I copied both himem.sys and emm386.exe from my Windows 98 partition
over to my WFWG 3.11/Dos 6.22 partition. Windows WFWG 3.11 now sees the
160 megs of ram I have and works fine with it.
It seems from talking with others that msdos 6.22 has a bug in the
supplied 'mem' program - it seems to only be able to see and report on
the first 64MB.
It seems a couple of other DOS programs get all upset and report 32MB of
RAM - looks like their RAM size count 'wraps' at 64MB.
Do you or anyone else know of a mem command clone that runs under dos
6.22 that doesn't have this bug or how to get the mem command from Win
95/98 to run under dos 6.22 since it was said to work properly?
Here's the output from the dos 6.22 mem command:
