Board:via/pc2500e

The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

The VIA pc2500e, V1.0C

This page describes how to use coreboot on the VIA pc2500e mainboard. It is maintained by Uwe Hermann.

Note that the via/pc2500e code will likely also work for the PC2000, PC2000e+, PC2500, PC2500e+, or PC2500g (though this is untested).
