As shown in my signature, I have Windows 98 running on 768 MB RAM on one desktop
and 1 GB of RAM in the other.
You need to add the entry MaxPhysPage=30000 to the [386Enh] section
of (Windows)\System.ini , to limit the physical RAM used to 768 MB.
Since System.ini is only loaded in Normal Mode, this does mean that a Windows 98
PC with 1 GB of physical RAM will not boot in Safe Mode (or in Selective Startup
mode with "Load System.ini File" unchecked) unless some of the physical RAM is removed.
My 768 MB PC does boot into Win98 Safe Mode without a problem!
This page (http://thpc.info/ram/vcache98.html)
has some excellent information. Scroll down to the "Large RAM PC's" section near
the bottom.
From my tests when setting up others' PC's:
I did get Win98 to boot in Safe Mode on a PC with 1 GB of RAM when 64 MB was assigned
(by the BIOS) to integrated video (so Win98 'saw' 960 MB RAM), but the MaxPhysPage=30000
line was still needed to correct strange errors occuring in Win98 Normal Mode (biggest
of which was, no file downloads would happen from any browser, IE6, Firefox or Opera!)
The couple of times I've tried to run 2 GB of Physical RAM in a Win98 system, that
just kills 98 dead no matter what! 98 can only address 2 GB of RAM in total (physical,
plus the hard drive paging or 'swap' file), so that much physical RAM plus the AGP
aperature is something it can't deal with, 'tweaking' or not......
