# 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

Type | Value
--- | ---
Socketed flash | no
Model | MT25QL128
Size | 16 MiB
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. Remove the jumper once coreboot is installed.

### 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.
