# HP Compaq 8300 Elite USDT
|
||
|
|
|
||
|
|
This page describes how to run coreboot on the [Compaq 8300 Elite USDT] desktop
|
||
|
|
from [HP].
|
||
|
|
|
||
|
|
## Flashing coreboot

### Internal programming
|
||
|
|
|
||
|
|
TODO: investigate

||
|
|
|
||
|
|
The board has two jumpers that might be relevant: FDO (Flash Descriptor Override) and BB (?).
|
||
|
|
|
||
|
|
### 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`.
