[UCLA-LUG] Linux Ram?

[Stephen Weglein]

Hi,
I don't know what distribution you are using but the command to inform Linux
how much memory you have is:

append="mem=128M"

Note that it says mem not ram!!

This works for me in Mandrake 6.0-7.0 and Redhat 6.0, and 6.1!   Perhaps
other distro's use a different command (though I doubt it!)

In my lilo.conf  put it after the line:
root=/dev/hda3

I have included my lilo.conf below!


boot=/dev/hda3
map=/boot/map
install=/boot/boot.b
vga=normal
default=linux
keytable=/boot/us.klt
prompt
timeout=50
message=/boot/message
other=/dev/fd0
 label=floppy
 unsafe
image=/boot/vmlinuz
 label=linux
 root=/dev/hda3
 append="mem=384M"
 read-only

Also It is not that linux doesn't know how much memory you have its that
bios doesn't report your memory in a way that linux needs!  Some bios's do
and some don't!  My former motherboard bios broadcast the correct memory
settings to linux,but, when the motherboard was changed the newer one did
not!

Of course be sure to run lilo when you have changed the file as root
