Hello Folks,

Environment: linux 2.2.16smp
RedHat 7.0

I am setting up a system with 1GB RAM recongized by the
BIOS during power-on procedure.

This system having troubles, I set a top command and
with surprise I got this status:

4:33pm up 4:42, 3 users, load average: 4.18, 2.01, 1.09
125 processes: 123 sleeping, 2 running, 0 zombie, 0 stopped
CPU0 states: 9.1% user, 9.0% system, 8.0% nice, 80.1% idle
CPU1 states: 20.0% user, 6.1% system, 20.1% nice, 72.0% idle
Mem: 63892K av, 62480K used, 1412K free, 15076K shrd, 5192K
buff
Swap: 514040K av, 260556K used, 253484K free 11804K
cached

My problem are the 63892K

I remember there is a solution to turn around this problem
forcing LILO to configure 1GB saying, I think but not
sure:

append='memory=1024'

I searched in the lilo doc for memory parameter definition, but
as being coverd by append parameter I found nothing.

Question 1:
Do you have an idea about the reason Linux is using 64MB ?

Question 2:
Is this append command correct to turn out this problem ?

Question 3:
Where can I found informations about append variables wich
are related in fact with modules parameters ?
How to find on source code which module will read the
memory parameter ?

Thanks in advance.

Bye
