How do I configure GRUB to see all of my memory?

How do I configure GRUB to see all of my memory?

You can specify the amount of memory on your system if your computer is not recognizing all of it. For example if your system says you only have 128 MB of RAM and you know for sure you have 256 MB, then you can specify that in your grub.conf file, located at /boot/grub/grub.conf

What you want to do is add the following syntax mem=M to the kernel line of your grub.conf file. So for instance if you were specifying your system had 256 MB in the grub.conf file, it would look something like this.

splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Enterprise Linux AS (2.4.21-15.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-15.EL ro root=LABEL=/ mem=256M
initrd /initrd-2.4.21-15.EL.img
title Red Hat Enterprise Linux AS (2.4.21-9.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-9.EL ro root=LABEL=/ mem=256M
initrd /initrd-2.4.21-9.EL.img
