# ASUS P8H61-M Pro

This page describes how to run coreboot on the [ASUS P8H61-M Pro].
|

|
|
## Flashing coreboot

```
|
||
|
|
|
||
|
|
The flash IC is located right next to one of the SATA ports:
|
||
|
|
|
||
|
|
|
||
|
|
### Internal programming
|
||
|
|
|
||
|
|
The main SPI flash can be accessed using [flashrom]. By default, only
|
||
|
|
the BIOS region of the flash is writable. If you wish to change any
|
||
|
|
other region (Management Engine or flash descriptor), then an external
|
||
|
|
programmer is required.
|
||
|
|
|
||
|
|
The following command may be used to flash coreboot:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom
|
||
|
|
```
|
||
|
|
|
||
|
|
The use of `--noverify-all` is required since the Management Engine
|
||
|
|
region is not readable even by the host.
|
||
|
|
|
||
|
|
## Known issues
|
||
|
|
|
||
|
|
- There is no automatic, OS-independent fan control. This is because
|
||
|
|
the Super I/O hardware monitor can only obtain valid CPU temperature
|
||
|
|
readings from the PECI agent, whose complete initialisation is not
|
||
|
|
publicly documented. The `coretemp` driver can still be used for
|
||
|
|
accurate CPU temperature readings.
|
||
|
|
|
||
|
|
- me_cleaner breaks LPC bus and attached components!
|
||
|
|
- PS/2 mouse doesn't work
