#Breaking the 64MB Limit
2 messages in this thread
I've installed 128MB of RAM into a couple of my DELL Dimension p90's.
Upon bootup, they do a RAM count up to 128MB but DOS' mem command
tells me I only have 64MB and so does 3D Studio.
I know that 3DS is able to access more than 64Meg because I recently
installed 106Meg into a Compaq & 3DS was able to use 104 of it.
I've tried all combinations of qemm, emm386 etc etc, without any
joy.
Any suggestions would be greatly appreciated.

Hi Andy,
<< where's my memory.. >>
Here's a repost from Jamie Clay..(slightly dated but still valid)
"If you ever have someone call in who has a system with more memory
than AutoCAD or 3DS show available, here is one possible solution.
(First, does all the memory count up during initial boot?, if so read
on)
o Get QEMM 7.04 (actually you can't yet purchase this, the patch is on
CIS in the QEMM forum)
o Then you use the(undocumented) SCANMEM command to display the amount
of memory the machine has. SCANMEM returns a memory range called
USEMEM.
o That range then needs to be plugged into the QEMM386.SYS's USERAM
option in the CONFIG.SYS.
Example: DEVICE=C:\QEMM\QEMM386.SYS RAM USERAM=XXXXX-XXXXX
From there it works like a champ. Note – you needed to add the RAM option to
get Windows to work with it."

I had trouble with Jamie Clay's instructions until I got on the QEMM forum and
learned that I had to boot my computer "clean" before I ran SCANMEM. This
means when "Starting MS-DOS…" is displayed, press F5 to bypass your
config.sys and autoexec.bat. _Then_ run SCANMEM and add the appropriate
"USERAM=XXXXXX-XXXXXXXXX" to your QEMM line in config.sys.
