After a tip in a Swedish Ubuntu forum about trying *BSD to see if it's a kernel bug I googled the problem again.
I then found the following:
http://www.geocities.com/rlcomp_1999/memory.html#METHOD2
http://www.linuxquestions.org/questions/linux-newbie-8/not-enough-ram-31594/

So now I know this is a common problem with Compaq! Crying or Very sad

I have tried add the mem option to the kernel command in Grub, but I then got:
Code:
BUG: int 6: CR2 00000000

So that didn't work.

I have also red the Grub manual and ther is a command called "uppermem". The manual sas that GRUBs BIOS probe can pick up all memory of all new machins the auther ever heard of, but this is an old machine! And Grub only repports 64Mb!
Well the command worked for Grub, and after telling Grub ther is 319Mb it reports back there is 319MB, but when I boot it's back to normal!

To morrow i will borrow a 128Mb modul from a friend to see if there is any diffrense.

Found a thread on http://ubuntuforums.org/showthread.php?t=814133&highlight=can%27t+find+all+ram&page=4 where there is a guy having the same (i think) problem as I.

The funny thing is that when i run dmidecode I get the following answere:

Code:

and if I understands the other thread this means that BIOS repports correct to Linux...

Why, why, why.... It hurts!!
