This page describes how to install and customize Gentoo Linux  so that it will run nicely on a Zepto Znote 4200 .
Znote 4200 hardware
The Znote 4200  being a fairly new laptop is off course built on Intel's platform for laptops: Centrino. Apparently the hardware Zepto used for the Znote 4200  is similar or maybe even the same as on the Compal CL56 , so this guide might apply to the CL 56  as well.
I've attached the output of cat /proc/cpuinfo and lspci, so that you can check if you have similar hardware.
