This page describes how to run coreboot on the [Compaq 8200 Elite SFF] desktop
|
||
|
|
from [HP].
|
||
|
|
|
||
|
|
## TODO
|
||
|
|
|
||
|
|
The following things are still missing from this coreboot port:
|
||
|
|
|
||
|
|
- Extended HWM reporting
|
||
|
|
- Advanced LED control
|
||
|
|
- Advanced power configuration in S3
|

### Internal programming
|
||
|
|
|
||
|
|
The SPI flash can be accessed using [flashrom].
|
||
|
|
|
||
|
|
### External programming
|
||
|
|
|
||
|
|
External programming with an SPI adapter and [flashrom] does work, but it powers the
|
||
|
|
whole southbridge complex. You need to supply enough current through the programming adapter.
|
||
|
|
|
||
|
|
If you want to use a SOIC pomona test clip, you have to cut the 2nd DRAM DIMM holder,
|
||
|
|
as otherwise there's not enough space near the flash.
