# 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.
