do you mean from a technical perspective or from a "what inmy map is
causeing a Page Fault in Quake" perspective....  I have alot of the
former in one of my maps... the most descriptive message I ve recieved
after trying the same map in various versions of Quake was 'Hunk
Misaligned in BSP' all other versions produced page faults....

technically .. PFs are generally caused when a peice of code tries to
access a memory address that is invalid.... meaning that its not part of
the allocated memory for the program... things that cause this are bad 
data files (BSPs) that say that 'oh yeah.. info for brush #214 can found
at address 0xf45a ... and then Quake looks for it there and discovers
that address f45a actually belongs to notepad or Explorer...

other things can cause page faults too... but the above description, I
think, is the one most pertinant to our Quake editing... also I could be
wrong about exactly what is causeing PFs in Quake sometimes, cause I
have no clue about Quake internal code.. Im just theorizing based on my
development experience...
