Recently I have changed my kernel from 2.4.31-grsec to and I can't resolve this problem: After changing my OS (Debian Etch), it sees only 884 MB of the physical memory but i have 1Gbyte (2x512MB) installed in my box and HIGHMEM (4gb) support is already enabled.

free -m:

What should i do? Sry for my bad english and thanks you for youre answers! :>

Can you be sure that this config really relates to your running kernel?

Do you have a shared RAM display card installed which is using some of
the RAM?

(Just two random thoughts really - you appear to have everything
correctly set up!)

Omg, perhaps you are right, i'm not sure, because this kernel was compiled by my friend and i said him to recompile the kernel because i changed the memory support and he said he has recompiled the kernel and restarted the machine.

uname -a:
Linux muranyi #1 Tue Jul 26 03:04:39 CEST 2005 i686 GNU/Linux

ls -all /boot:
*lots of file*
-rw-r--r--   1 root root   29391 Aug  1 13:36 config-
*lots of file*

The dates are not the same, does it mean it isn't the config of the running kernel? (Might my friend was bit a lazy?^^)

I dont have any shared RAM display card and it was working correctly with Kernel 2.4.27-grsec/2.4.31-grsec.
