I recently bought 64megs of additional ram to put next to the factory
installed 64 on my gateway celeron 400. the boot messages indicate that
it's finding all 128megs of ram, but typing "free" shows that the kernel
is only using 64meg. I've tried swapping the dimms and recompiling the
kernel (2.2.14, with maximum memory 1GB), but can't get the memory to
work. I'm fairly certain that the chip works, but I don't know what else
to try. any advice?
