Memory problem.

[Alex Jørgensen]

Hi

I have a strange problem with my redhat 6.2 linux server.
It have 256 Mb ram installed but linux only sees 64 Mb, if i run "top".
I use to run Windowz Nt with no memory problem and the BIOS also sees
the 256 Mb.
My configuration is a Dual 400 Mhz intel, with a super micro ( p6dge )
motherboard.
and the 256 pc100mhz ram.

Does any of you have an solution to my problem?
