Originally posted by Unregistered running mem /c with vdms tells me, that i have 602.3 K free.
loaded is:
msdos (size 11.7k)
kbd ( 3.2k)
emm (0.2k)
himem (1.2k)
mouse (12.2k)
command (3.0k)
kb16 (6.0k)

For best results, you really need to display the whole report: Upper Memory, etc...

i have seen guys on this forum, having free something like 612kbyte.

Believe it or not, this is still directly related to your actual hardware. For some it is nearly impossible to create EMS memory.

so now i wonder, how can i free memory?

Hard to tell without a more detailed report. The only thing I notice is that the mouse driver is loaded into conventional memory. Is there not enough space to load it into upper memory?

here's what mem /c says when i run it under VDMS.

EMS was no problem after i've disabled USB in the bios.

Any ideas how to free more? 😀

thanks in advance,

vwiff! That makes no sense.

Well, I was going to suggest making room in upper memory to cause the mouse driver to load there...except it doesn't appear to be any!?

yeah, it's pretty odd.

when i run mem /c from MS-command line, i have upper memory (see below)

i don't know why there is none when running VDMS.
ideas? 😀

It is not strange, actually. It seems that you have only 64KB of upper memory space available, that is being used by the EMS frame when you run mem /c with default VDMS settings. When you start a regular command prompt the default is no EMS, so these 64KB are free for loading programs high into UMBs.

I have the same situation with my notebook, so I set each VDMS shortcut I create according to the game I want to run (btw, you are using the Launchpad, aren't you?). If the game needs only EMS I do not load DOSX (for DPMI support), since it would eat some 37KB of conventional memory. For games that depend on DPMI you can safely disable EMS (not needed for DPMI under Windows 2000/XP) and gain 64KB of UMBs to load some TSRs high.

EMS was no problem after i've disabled USB in the bios.

Any ideas how to free more?

None, unless you have something else to disable in your BIOS. For many recent motherboards, getting free UMBs is somehow difficult, if not impossible.
