1GB system working with 64MB - Solved

Problem solved.
This is one top output:
5:47pm up 21 min, 2 users, load average: 0.99, 0.70, 0.48
110 processes: 109 sleeping, 1 running, 0 zombie, 0 stopped

CPU0 states:  0.1% user,  2.4% system,  0.0% nice, 96.4% idle
CPU1 states:  0.1% user,  5.4% system,  0.0% nice, 93.5% idle
Mem:   906424K av,  904296K used,    2128K free,   19808K shrd,   20956K 

buff
Swap: 514040K av, 17176K used, 496864K free 710672K
cached

The system is using now 906MB rather than 1024, but at this time of the day I am quite happy comapred with the 64MB used before. Next step will be to go on 2.4.x
Thanks

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
