This page describes how to use coreboot on the VIA EPIA-CN mainboard.

This page is a work in progress.

VIA EPIA CN13000G
VIA EPIA CN10000EG

The earlier versions of the Epia-CN use a Winbond Super I/O vs the VIA in the later versions.

Use this to extract the vgabios from the factory BIOS:

$ dd if=/dev/mem of=video.bios.bin.4 bs=65536 count=1 skip=12

Ubuntu 8.04 openchrome drivers support X without the need for bochs or vgabios. viafb support as a payload is in the works.
