This page describes how to run coreboot on the HP Z220 SFF Workstation desktop from HP.
The following things are still missing from this coreboot port:
+---------------------+-------------+ | 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 | +---------------------+-------------+
The SPI flash can be accessed using flashrom.
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.
