Does anyone use 2G RAM and Video Card with 256MB RAM can boot win98 successful ?
Yes, this is now also my case of troubles:
I still use Win98SE (multiboot with DOS, WXP, Linux) and I just upgraded
RAM from 1GB to 2GB (my system is 945/ICH7 mb & 7600GS PCIE 256M VGA).
I hadn't any problems under 98SE with 1G, as I know about VCACHE issue I
limited it in system.ini:
MaxFileCache=261120
MinFileCache=32768
ChunkSize=4096
...
MaxPhysPage=40000
As this works fine I didn't expected further problems with adding
more mem. I just pull two 1G DIMMs and when 1st booting 98SE it
hangs in text mode screen with blinking cursor. I tried safe mode
but got insufficent memory message during boot. When I tried normal
mode again, it went further but I got only VGA mode 640x480/16
with message "There is a problem with your display settings. The
adapter type is incorrect, or the current settings do not work
with your hardware [OK]". Then display dialog appeared. I tried
to set some higher resolution, reboot but then it hanged again.
I search a lot of topic on web and try adjusting vcache size and
lowering physpage limit, even some patched vcache.vxd but nothing
helped.
I also found Loew's memory limit patch demo. 1st problem was that I
use czech win98se so patch didn't applied. I had to seek some
torrents to get eng. ISO. I backup my system and made clean
win98se-eng installation. I needed to modify system.ini physpage
to complette installation to solve insuficent memory error.
System seemed to work OK with 2GB installed - seeing only 1GB.
But after I installed ForceWare 82.69 drivers for my nVidia
it become unbootable like my CZ version, hanging during boot.
So then I tried Loew's parch 3.2 demo. Now it successfully patched
the english files. I booted safe mode and it booted OK and
even show up all 2GB.

Well but the problem is that in safe mode VGA drivers are not
loaded so I cannot see if it will works together like in normal
mode. I don't need to use whole 2GB under 98SE (1G is enough) I
just want boot it in normal mode with display driver in usable
resolution.
I also tried to change VGA to my older 6600GT 128MB and same problem.
It seems like VGA LFB memory mapping conflicts with something else.
But I don't understand why. If I'm right, W9x use for this system area
located C0000000-FFFFFFFF. My VGA use LFB at always at D0000000-DFFFFFFF
despite I use 1GB or 2GB RAM it's in system area where it fitted well before.
Do you think that Loew's patch (full) will solve it or is there other way
to use it with limited memory?
Can be size of memory limited at very low HW level? I mean e.g. program
945 MCH chipset to temporary disable one DIMM bank to reach same
effect like when DIMM removed physically?
