I have 1280MB of RAM in my computer. When I was running 98se I had to convince it to not use any more than 1GB (it would reboot every time it booted into windows with more than that). I also found that whenever I rendered a large scene and it used ~640MB of RAM it would crash, every time (I watched sysmon.exe and crashed it 10 times in a row to make sure of this). The memory fix that cruzan mentioned might fix this problem, but it might still not work right on 98. I have upgraded to XP and haven't had the problem happen again (and I have seen it us over 1GB of m RAM)
