Re: How to find server performance

["Vivek Chawla" <vivek.chawla@xxxxxxxxxx>]

regarding RAM, I was wondering if anyone could help me figure out what is
the way to configure lilo and grub to use all the 256M of RAM.

Currently, the linux mandrake that I have uses only 64M RAM even though I
have 256M of RAM on my comp.

Kindly help

Vivek
