Not all memory available

There's a kernel config option called "High Memory Support" with three
options: less than 1GB, between 1 and 4GB, and greater than 4GB.

fix:  a recompile would be required in this case.

If you want to check your current kernel config to see if that's the
problem, look at /boot/config-<your_kernel_version> and find a few lines
starting with CONFIG_HIGHMEM. All should be commented out (line starts with
#) except the one that's actually enabled.

Besides... check if your bios supports that
