I am running a dual boot 98SE/2K system, and have no problems with 512MB of RAM. In 98SE, I have added the ConservativeSwapfileUsage=1 line in System.ini/386Enh, (which forces the OS to use all available RAM before hitting the Swapfile) and set Virtual Memory to be handled by Windows. I never have had a swapfile started, and 98SE runs smooth as silk.
