This page describes how to run coreboot on the [ASUS P8H77-V].
+---------------------+----------------+ | Type | Value | +=====================+================+ | Socketed flash | yes | +---------------------+----------------+ | Model | W25Q64FVA1Q | +---------------------+----------------+ | Size | 8 MiB | +---------------------+----------------+ | Package | DIP-8 | +---------------------+----------------+ | Write protection | no | +---------------------+----------------+ | Dual BIOS feature | no | +---------------------+----------------+ | Internal flashing | yes | +---------------------+----------------+
The flash IC is located beside the SATA ports (circled):
Unlike ordinary desktop boards, the BIOS version 3202 of ASUS P8C WS does not apply any write protection, so the main SPI flash can be accessed using flashrom, and the whole flash is writable.
The following command may be used to flash coreboot. (To do so, linux kernel should be started with iomem=relaxed
)
# flashrom -p internal -w coreboot.rom
The flash chip is a socketed DIP-8 SPI flash, so it's also easy to remove and flash externally.
