for 32 bit OS architectures , technically a process can access 2^32 of memory space .
Means 4 gigs .But with PAE feature of the kernel allows a process to use more memory .
Physical Address Extension (PAE) is a feature to allow (32-bit) x86 processors to access a physical address space (including random access memory and memory mapped devices) larger than 4 gigabytes.

I've just replaced the secondary disk drive (was 4 Gb) with a Seagate Barracuda 7200 200 Gb. However the OS seems to think this is only 500 Mb and a spin speed of 5400, although it correctly recognises the drive as Seagate ST3200822A.
I take it that it still thinks the old drive is attached.... (1 Reply)

JMKMF(1) General Commands Manual JMKMF(1)
NAME
jmkmf - runs jmake with the correct options
SYNOPSIS
jmkmf [ top-level dir [ current dir ] ]
DESCRIPTION
Jmkmf is a wrapper which calls jmake with the correct options, defining the symbols TOPDIR (location of the top-level directory) and CURDIR
(current directory). The generated Makefile.SH is then ran through /bin/sh to produce a Makefile.
Jmkmf is useful when you generate a makefile for the first time.
When ran without arguments, jmkmf will scan the directories upwards, looking for a .package file marking the top of your sources. It will
then derive the top-level directory and the name of the current directory by itself.
Once you have a Makefile.SH generated by jmake, and have run Configure already, you can use make Makefile.SH to build the Makefile.SH again
and make Makefile to run the Makefile.SH through /bin/sh. To use the recursive commands, you have to append an 's' at the end of the name
as in make Makefiles.SH and make Makefiles.
