hi sir
  Iam using linux os in friendlyARM
 I am having 64 MB of ram so it is using 64 MB  but i want to limit it, it
means i want 100 kb memory for future usage so restrict 64 MB ram to
  (64MB-100KB) (shortly: don't use last 100 KB ram) 
   how it can be done ....can any one suggest me

u can use ulimit command ulimit -a to view the information and ulimit -m to
set the memory in kb
            ex; ulimit -m 65436

Start your kernel with "mem=64M" for example. This will prevent Linux from
using the last 1 MiB from your real memory.

Ups, use "mem=63M" instead :)
