Ok, since I did the tutorial on virtual memory I have been testing the operating system on multiple sets of hardware. When I test in bochs or on my laptop (pentium M 1.8 ghz dell inspiron 600m) I get page fault errors; however, I have no page fault problem in virtualpc or on my old packard bell legend 2440. can anyone tell me what is going on w/ the page faults?

Hello,
I cannot look into the issue without knowing the address that it page faults to. Run it in Bochs, and please post the bochs crash log here.
