Hi,

I have a PC with 2 gigs of RAM, running the latest stable 2.6 gentoo-sources kernel. The BIOS confirms that it recognizes 2Gb of RAM, however, I get the following output:

did you enable high-memory support in the kernel?

This will show your kernel memory settings (more than you really need but it works)
#grep MEM /usr/src/linux/.config

you probably have:
CONFIG_NOHIGHMEM=y
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set

you probably want:
# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
# CONFIG_HIGHMEM64G is not set

I just notices that you resloved your problem before I posted.
