We're testing some x86 systems with more than 1GB of RAM. Linux on x86 seems to be limited to 1GB of physical memory. This suprised me a bit since I thought 386 PTE's had 20 bits for physical page addresses (4GB physical). Is there a 1GB physical limit, what's the reason for the limit, and what would need to change to increase this to 4GB? (i.e. Where did those other 2 bits go?)
I also seem to be seeing a limit on swap space of 1GB. What about increasing that too?
Thanks,
Larry
