Re: Tweaking /boot/grub/menu.lst to use 2GB RAM

Hi all

I'm seeking some advice on the best option to enable my 2.6.22-3-686 kernel to utilise the 2Gb RAM properly.

What is the best tweak to the /boot/grub/menu.lst file in order to enable my kernel to recognise and utilise the additional RAM? Looking through this file, the relevant section appears to be this commented part:

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

The instructions are to not uncomment the section, but just to edit. So would my edit be to add
memtest86=true or memtest86=false

or would I simply add the line to menu.lst between the two markers that reads:
mem=2097152M #2GB RAM

The latter is what I understand from the bootparam(7) man-pages, but I'd like to confirm that my understanding is accurate before I commit.

Thanks



You really shouldn't have to add anything to see 2G of ram. If you aren't I suspect that there is something else going on with your system.
What does grep MemTotal /proc/meminfo tell you? At boot, is the BIOS seeing 2G?
