+# HP Compaq 8300 Elite SFF
+
+This page describes how to run coreboot on the [Compaq 8300 Elite SFF] 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
+

++---------------------+------------+
+| In circuit flashing | yes        |
++---------------------+------------+
+| Package             | SOIC-16    |
++---------------------+------------+
+| Write protection    | Yes        |
++---------------------+------------+
+| Dual BIOS feature   | No         |
++---------------------+------------+
+| Internal flashing   | yes        |
++---------------------+------------+
+```
+
+### Internal programming
+
+Internal flashing is possible. The SPI flash can be accessed using [flashrom],
+but you have to short the FDO pins located near the rear USB3 ports on the
+motherboard using a jumper, to temporarily disable write protections while on the
+stock firmware. Once the coreboot rom is flashed, one should remove the jumper.
+
+### 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.
