Wrong memory size found in Linux

The Linux kernel will detect various settings from your computer configuration. This includes the size of
memory you have. In some cases, it will find the wrong size. For example, it could find only 64 megs of
memory when in fact you have 128 megs.
The trick here is to specify the amount of RAM memory you have with the "mem=" parameter. Here is what
you would type when your system boots if you have 128 megs of memory:
LILO boot: linux mem=128M
This will tell LILO to load the linux kernel with 128 megs of memory
