Max RAM Supported

[Amit K Tiwari]

Hi,

I have just installed YDL 4.0. The OS does not show all 6GB DRAM I
have in my Power Mac G5. It shows only 1.97GB (I ran top to see how
much physical memory I have). Looking at the net,
http://archive.linuxsymposium.org/ols2003/Proceedings/All-Reprints/Reprint-Bligh-OLS2003.pdf
says that kernel 2.5 should support approx 32GB of memory.

Do I need to re-build the kernel to enable the support for all of
available memory? If yes, with what options? 'High Memory Support' is
already enabled in the kernel config.
