EMM memory problem in dosbox

[bumbla]

Recently I had a nostalgic feelinf and I was trying to run of of the very old games, I haven't played from ages. It's "Master of Magic" -

here I stucked on not enough emm memory problem. Regardless of all settings I always get 0 available memory in XP dosbox, I guess I need some

expert advise with it. I read verious forums and I see it's not about this particular game, as other had no problem with running it under xp,

it looks like something is blocking emm in dosbox. When I call "mem" in command promopt I get something like this:

16777216 bytes contiguous extended memory
0 bytes extended memory available
15580160 bytes XMS memory available
MS-DOS loaded to HMA

What I have tried: I set EMS memory in pif, checked lots of settings, tried all compatibility modes, edited config.nt, now it looks like

that:

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=40
EMM=RAM

autoexec.nt goes like that:

lh %SystemRoot%\system32\mscdexnt.exe
lh %SystemRoot%\system32\redir
lh %SystemRoot%\system32\dosx
SET BLASTER=A220 I5 D1 P330 T3

I read in some forum that one had similar problem caused by motherboard monitoring software, I went to device manager, showed hidden devices

and under non-plugandplay devices I tried uninstalling everything concerning motherboard and graphic card - no effect. I tried booting in

safe mode, no effect either - 0 bytes extended mem available.

I'd appriciate any tip on how to solve this.

here's some info on my system:
Windows XP pro (polish)
512MB ram / athlon 1600+
epox motherboard / onboard sound - drivers installed
asus graphics GeForce2 GTS running on recent detonator instead of supplied drivers
other devices and progs which may possibly have something to do with it:
adaptec scsi adapter on pci - AH2940 (not plugandplay)
adobe ATM installed
