This page describes how to run coreboot on the ASUS P8H61-M LX.
+---------------------+------------+ | Type | Value | +=====================+============+ | Socketed flash | yes | +---------------------+------------+ | Model | W25Q32BV | +---------------------+------------+ | Size | 4 MiB | +---------------------+------------+ | Package | DIP-8 | +---------------------+------------+ | Write protection | no | +---------------------+------------+ | Dual BIOS feature | no | +---------------------+------------+ | Internal flashing | yes | +---------------------+------------+
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.
S3 suspend/resume does not work. This is the case for both coreboot and the vendor firmware, tested with Linux 4.9, Linux 4.17, and OpenBSD 6.3. Interestingly, it is possible to resume from S3 with Linux, but only if the resume is started immediately after the suspend.
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.
