I have a 32bit box running linux. It has 8 GB. I understand in a 32
bit address space you can't address of 4 GB. Since linux uses virtual
memory I have read that one process can access up to 4 GB.
I read to use this on systems with more than 4 GB of physical ram you
must have PentiumPro with PAE (Physical Address Extension).
I see this:
[root at hela init.d]# cat /proc/meminfo | head -n2
MemTotal: 2074876 kB
MemFree: 1270664 kB
here is my cpu info
[root at hela init.d]# cat /proc/cpuinfo | grep name
model name : Intel(R) Pentium(R) III CPU family 1400MHz
model name : Intel(R) Pentium(R) III CPU family 1400MHz
I was told these are Xeon chips. Are Xeon classified as Pent III?
and do these chips have PAE?
I guess my ultimate question is can I use the 8GB of ram I have at
least at a per process level?
