Very Computer

Is there anybody who can use more than 64MB ?
Do you have any idea what I can change in the kernel sources ?

Many thanks for helping me

  append = "mem=128M"

in your /etc/lilo.config to inform the kernel about the real mem size.
The linux bootstrap uses the BIOS call 0x15 fct 88 which returns extended mem
size in 1kB as 16bit number, i.e. max 64kB.
(this was explained and posted Gerhard Traeger, and others)

The BIOS will only return memory sizes up to 64MB. Beyond that you have to
give LILO an argument to tell it how much memory there is.

You may experience severe performance problems if you have less than 512k
of L2 cache.
