+# HP Compaq 8200 Elite SFF
+
+This page describes how to run coreboot on the [Compaq 8200 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
+
+```eval_rst
++---------------------+------------+
+| Type | Value |
++=====================+============+
+| Socketed flash | no |
++---------------------+------------+
+| Model | MX25L6406E |
++---------------------+------------+
+| Size | 8 MiB |
++---------------------+------------+
+| In circuit flashing | yes |
++---------------------+------------+
+| Package | SOIC-8 |
++---------------------+------------+
+| 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.
