1 edit | Can't See Full Memory On Server
I just installed CentOS 4.2 on a IBM Server loaded out with 16 gigs of memory. CentOS comes up and recognizes 8 gigs of memory only. I googled it and came across the kernel-hugemem. I am still having the same problems running on the hugemem kernel.
The bios see's all 16 gigs of memory so I know it's there.
Thanks in advance.

1 edit | You need to enable the CONFIG_HIGHMEM64G option for your kernel.
You can test if it's set
$ sudo zgrep -i HIGHMEM /proc/config.gz
# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set
CONFIG_HIGHMEM=y
or
grep -i HIGHMEM /usr/src/your_kernel/.config
EDIT: Just noticed that you said it sees 8GB already, that implies it might already be set. Worth checking though.
