In Win98, if you open System Monitor and add;
Unused Physical Memory
& Swap File in Use
You will see that 128mb is totally used up after opening Winders, Norton and IE 5.5
I'm stuck on 128mb as a "Bare Minimum" on W98 and 256 on XP
Make sure to invoke the sysedit tweak of ConservativeSwapfileUsage=1
and, check Network Server along with the msconfig lean out.
Sorry, I didn't notice that you'd alread gotten the figures from Crucial, my spedredin course didn't work
