+# 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.
