Hello,
A few days ago I installed another 1GB RAM in my laptop. However, the system can still see only less than 1 GB:
Code:

leo@LEO ~ $ cat /proc/meminfo | grep MemTotal
MemTotal:         904492 kB


What can I do? GRUB and Windows Vista (and Windows 7) recognize that now there are 2GB RAM, but Gentoo stills shows the old 1GB. Somewhere in the internet I found that the amount of memory can be passed to the kernel as an argument in grub.conf, but... shouldn't it just work without any additional actions?

Several possibilities here. 8)

0. Windows is a better operating system;
1. You are running Linux 32-bit kernel with "High Memory Support" turned off.

Take your pick. In first case remove Linux, in second rebuild your kernel. :P

:D

Option 0 is out of the question :)
I also thought about an option in kernel previously but then "Hey, 2GB is not much these days to require special settings" came to my mind. Oh well, I was wrong. Option found, kernel compiled and rebooted. Problem solved.
Code:

leo@LEO ~ $ cat /proc/meminfo | grep MemTotal
MemTotal:        2073688 kB


Thank you!
