# HP Z220 SFF Workstation

This page describes how to run coreboot on the [HP Z220 SFF Workstation] 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

## Flashing coreboot

### 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.
