I have my linux running on a compaq computer with 48M of mem. I used to
have problem detecting the mem above 16M. Add "append="MEM=48M"" to my
lilo solve the problem. Did you re-run lilo after you have changed the
lilo.conf? It could be the problem if you did not re-run lilo after
the config had been change. Good Luck!!!
