You will find that in the recent stable kernels....I would
recommend using a devel kernel such as 2.1.97....I have found it to be the
most reliable in the devel kernels and it will see all of your memory. I
can only say this of course because I don't run a ton of things like many
users, companies, etc do, so thus won't encounter too many probs
regardless what kernel I use. But if you try the devel's, they should
recognize all your memory without having to worry about specifing them at
boot time. I have 80 M in my machine and it recognizes it fine.

I booted from a floppy, removed the append statement in my lilo.conf and run /sbin/lilo. Again, I rebooted my machine, this time I specified mem=128MB in the LILO boot prompt. It encountered the same problem.
