HP Compaq Elite 8300 USDT

This page describes how to run coreboot on the Compaq Elite 8300 USDT desktop from HP.

Internal programming

Internal programming is possible. Shorting the Flash Descriptor Override (FDO) jumper bypasses all write protections.

External programming

Remove the lid. The flash chip can be found on the edge opposite to the CPU. There is a spot for a "ROM RCVRY" header next to the flash chip but it is unpopulated. If you don't feel like using a clip, you can easily solder a standard pin header there yourself and use it for programming.

Programming powers some parts of the board. Programming when Wake on LAN is active works great.

SuperIO

This board has a Nuvoton NPCD379 SuperIO chip. Fan speed and PS/2 keyboard work fine using coreboot's existing code for :doc:../../superio/nuvoton/npcd378.
