Sounds like the popular-and-easily-solved problem:
You need to pass the kernel, at boot time, a parameter apecifying how much RAM
you have.
This is easily done with lilo (/etc/lilo.conf on RH systems):
image=/boot/vmlinuz-2.2.14-5.0
label=linux
read-only
root=/dev/hda4
relevant line ---> append = "mem=192M"
password="yossi"
restricted
I cant exactly recall the way you pass that parameter with loadlin, but you
could easily find out with loadlin docs.
Boaz.
