saarb16 LQ Newbie Registered: Feb 2006 Posts: 3 Rep:	RHEL4 sees only 1GB out of 4GB RAM I have a 32bit x86 machine with 4GB RAM. I installed RHEL4, kernel 2.6.9-22. When I run free -m, total reads as 883. As far as I understand 4GBs does not require any special configuration as they exactly fit the 32bit limit. So where are additional 3GB? Saar
