# 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

| Size | 16 MiB |

| In circuit flashing | yes |

### 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.
