# HP Compaq Elite 8300 USDT
This page describes how to run coreboot on the [Compaq Elite 8300 USDT] desktop
from [HP].
## Flashing coreboot
```{eval-rst}
+---------------------+-------------+
| Type | Value |
+=====================+=============+
| Socketed flash | no |
+---------------------+-------------+
| Model | W25Q128BVFG |
+---------------------+-------------+
| Size | 16 MiB |
+---------------------+-------------+
| In circuit flashing | yes |
+---------------------+-------------+
| Package | SOIC-16 |
+---------------------+-------------+
| Write protection | No |
+---------------------+-------------+
| Dual BIOS feature | No |
+---------------------+-------------+
```
### Internal programming
Internal programming is possible. Shorting the Flash Descriptor Override
(FDO) jumper bypasses all write protections.
### External programming
Remove the lid. The flash chip can be found on the edge opposite to the CPU.
There is a spot for a "ROM RCVRY" header next to the flash chip but it is
unpopulated. If you don't feel like using a clip, you can easily solder
a standard pin header there yourself and use it for programming.
Programming powers some parts of the board. Programming when
Wake on LAN is active works great.
## Technology
```{eval-rst}
+------------------+--------------------------------------------------+
| Northbridge | :doc:`../../northbridge/intel/sandybridge/index` |
+------------------+--------------------------------------------------+
| Southbridge | bd82x6x |
+------------------+--------------------------------------------------+
| CPU | model_206ax |
+------------------+--------------------------------------------------+
| SuperIO | NPCD379HAKFX |
+------------------+--------------------------------------------------+
| Coprocessor | Intel ME |
+------------------+--------------------------------------------------+
```
### SuperIO
This board has a Nuvoton NPCD379 SuperIO chip. Fan speed and PS/2 keyboard work
fine using coreboot's existing code for :doc:`../../superio/nuvoton/npcd378`.
