I added memory to my Redhat system to bring it up to 2 gigs. BIOS sees 2 gigs, but the OS only sees 1.

[root@db6 etc]# cat grub.conf
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-28.8smp)
root (hd0,0)
kernel /vmlinuz-2.4.20-28.8smp ro root=LABEL=/
initrd /initrd-2.4.20-28.8smp.img
title Red Hat Linux-up (2.4.20-28.8)
root (hd0,0)
kernel /vmlinuz-2.4.20-28.8 ro root=LABEL=/
initrd /initrd-2.4.20-28.8.img

I tried adding mem=2048M to the kernel line, but that doesn't do anything. I have an identical system with an older kernel that sees the memory without any problem. What do I need to do to see the memory?

thanks,

Hmm, maybe it only sees the 1 gig, but the 2 gig is there, and its in your system. So just because the OS doesent see it, doesent mean its not there, and working.

Maybe.
