Subject: 1GB system working with 64MB

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

"mem=" is documented in the kernel documentation
(...linux/Documentation/i386/boot.txt):

mem=<size>
<size> is an integer in C notation optionally followed by K, M
or G (meaning << 10, << 20 or << 30). This specifies to the
kernel the memory size.

Add this:

append="mem=1024M"

to your lilo boot profiles.

... 2.4 correctly detects memory size more often than 2.2.16 ...

If you upgrade to the 2.2.19 kernel, this will just work,
no need for extra options. (Red Hat also has a 2.2.19 kernel
available as errata release for 7.0)
