Hi guys,

so, finally got the extra RAM.

Compaq 486
100 MB RAM (4 MB motherboard-embedded + 3 modules of 32 MB each to fill all the 3 available slots).
MS-DOS 6.22
Everything installed and configured (including Himem.sys and EMM386 NOEMS), but.... Himem only sees about 32 MB XMS!
Everything else vanishes into thin air, as if it wasn't there (but the RAM count when I turn on the computer scans it all, lots of time, and finally gives 102400 KB OK).

What do I do? How do I get HIMEM to see at least 64 MB of RAM, if not all the 100 MB (well... technically 99 MB, as the below 1 MB is not of Himem's competence).

Or, is MS-DOS 7.1's Himem compatible with MS-DOS 6.22?

Thanks!!!

Solved!

I removed the 3rd 32MB SIMM module, so now I have 68 MB (4 soldered + 32 + 32), and HIMEM gets up to 64 MB XMS.

It's all good. 100 MB of RAM in an MS-DOS 6.22 system was a waste.

HIMEMX can handle large amounts of RAM and it's more efficient. I'd give it a try.

Oh wow, thanks bro! Never heard of it before.

Then, if I install HIMEMX, what should I use for UMB and, occasionally, EMS? EMM386 or JEMM386?

Thanks
