Hello Dan,
I have an Abit BE-6II rev 2.0 MB with a Pentium III 1 ghz processor and 768 meg of ram (PC133) installed. The OS is Win98SE, and I do not have any memory problems, so as far as Win98SE not being able to handle more than 128meg of ram, I would tend to disagree. When I first increased to 768 meg, I did have a problem. It was caused by a cheap, generic memory stick that was not compatible with my MB, during boot-up it would not always recognize all the installed memory. I replaced it with name brand memory and all the memory was then recognized during boot-up. After replacing the bad memory, I used a program called "Doc Memory Diagnostic" to confirm that all memory was working properly. simmtester.com
I also use a program called "Cacheman" to manually set all my memory caches, I disable virtual memory, and set my swapfile to a specific size (I use 100 meg). This program claims that it, "corrects generic problems on systems with more than 512MB of RAM", so it might help with your situation. outertech.com
Hope this helps you in some way.
