Whilst Win9x operating system such as Win Me can handle up to 2GB of RAM
(although often there are problems with greater than 1GB) it is essential
to limit the virtual cache to no more than 512MB since if you allow the
cache to exceed 512MB this will mean that you run out of upper memory
addresses and get Out of Memory errors. Note that this will still mean
that all memory is available to applications but is simply limiting the
amount used as virtual cache memory See KB 253912 - ""Out of Memory"
Error Messages with Large Amounts of RAM Installed"
(http://support.microsoft.com?kbid=253912).

Memory" (http://support.microsoft.com?kbid=296773). This makes reference
to an updated file vmm.vxd. Contact Microsoft, explain the problem, and
mention 296773 and you should be given details of how to obtain the patch
and the password of the day. Note that there should be no support charge
for this call other than for any telecom charges incurred in ringing
Microsoft.

Ok, I found the problem and found that I lied before.
I also installed another 512MB PC2700 DDR (in addition to the 512MB
3200 DDR already installed).
Doing that drove my video synch rate out of wack, and could be seen
on boot up!
When I removed the newly installed second RAM card, my video card
worked again.
Any suggestions on how to have my 1GB RAM and use it too?
I tried updating the video drivers www.s3graphics.com, but that did
not do it. The next update listed is for WinXP, and does not install
under ME.
