Ok sorry for my dummy question. I have 248 MB physical ram on my old world Mac that I mess about with Linux on. When I boot into Gentoo and do:

cat /proc/meminfo

it's saying around 140 odd is already active when I haven't really done anything.

Is this just how Unix-like OS's work ? My other OS X Mac is rather similar in that regard.

Or is it something to do with BootX having go through part of the normal Mac start up on old world machines, and never releasing that part of ram ?

Or is it something to do with (when I did make menuconfig for the Kernel yesterday) where it had some boxes already ticked about 16 RAM Disks. When I did help it said you should leave this alone unless you know what you are doing..so I did. Is it the case that for some reason the Linux kernel needs to create 16 RAM Disks to function ?

cheers

P.S I should add: no X installed yet

The ram is used for caching. It's normal and beneficial and better then if it were just idle. If it's needed, the kernel releases it, so don't worry about it. :)
