Synopsis: This article explains how to determine whether you need a HIGHMEM enabled kernel.

During boot, your system may tell you that you need a HIGHMEM enabled kernel. However, often systems boot so fast that you don't get a chance to read the message.

Fortunately, you can check by running a simple command at the command line. Log in as root and type :-

dmesg | grep HIGHMEM

If the system responds with

Use a HIGHMEM enabled kernel

Then you need to install such. You can find the instructions to do so in a separate item.
