I was wondering, I just installed 2 x 1 gig memory sticks in my computer and the BIOS recognizes them both, but when I run "cat /proc/meminfo" linux only dispays 1 gig. What's up with that? Is there some configuration I need to use when I compile the kernel? Why does it only show 1 gig?
Thanks.

The default kernel is not configured to handle memory above 1-GB, fix it....
Either recompile the kernel for large memory support or locate a kernel for your unlisted/unknown version of Linux that does.

Thanks, worked like a charm!
Did a make xconfig and under Pocessor type and features, High Memory Support I activated 4GB and recompiled the kernel. That did the trick...
Thanks again.
