# 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

Type | Value
--- | ---
Socketed flash | no
Model | N25Q128..3E
Size | 16 MiB
In circuit flashing | yes
Package | SOIC-16
Write protection | No
Dual BIOS feature | No
Internal 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.

In both case, if ME has not been completely disabled, ME/AMT Flash Override jumper had better be temporary closed for flashing to disable the locking of regions, and prevent ME to run and interfere.

## Side note

The mainboard of HP Compaq Elite 8300 SFF is very similar to the one of Z220 SFF, except that Compaq Elite 8300 uses Q77 instead of C216 for its PCH, and their boot firmwares are even interchangeable, so should do coreboot images built for them.
