# 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 ```eval_rst +---------------------+-------------+ | 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. ## Technology ```eval_rst +------------------+--------------------------------------------------+ | Northbridge | :doc:`../../northbridge/intel/sandybridge/index` | +------------------+--------------------------------------------------+ | Southbridge | bd82x6x | +------------------+--------------------------------------------------+ | CPU | model_206ax | +------------------+--------------------------------------------------+ | SuperIO | :doc:`../../superio/nuvoton/npcd378` | +------------------+--------------------------------------------------+ | EC | | +------------------+--------------------------------------------------+ | Coprocessor | Intel ME | +------------------+--------------------------------------------------+ ``` [HP Z220 SFF Workstation]: https://support.hp.com/za-en/document/c03386950 [HP]: https://www.hp.com/ [flashrom]: https://flashrom.org/Flashrom
