] How can Linux evade the limit?
The 640k limit? I don't know every litttle detail, but I reckon I'd
be the same way DOS4GW, Windows 3.11+, OS/2, etc use: Put the
processor in protected mode. This is only available in 386's and
higher processor. [286 had pmode but couldn't go back to real IIRC]
This mode gives you as much memory as your computer's got and easier
for programmers to define large memory blocks. eg to define a 5MB
table in DOS you'd have to jump trhough many hoops. in Linux just
define it. Unfortuneatley this almost makes programmers lazy: Look at
the MS RegClean report floating around. a max 50k program bloated up
to almost a meg!
The moral of the story: A 386DX can run almost anything but a 286
can't.
