The H8SCM motherboard is highly supported by coreboot-15h.
Board Variants
H8SCM
H8SCM-F
The H8SCM-F is identical to the H8SCM, but has an onboard BMC. It is compatible with the coreboot image for the H8SCM, but it is not known whether the onboard BMC will operate. The "JPB1" jumper can be used to disable the onboard BMC, effectively turning the H8SCM-F into the H8SCM.
Onboard BMC
The Nuvoton WPCM450 is a combined Baseboard Management Controller and 2D/VGA-compatible Graphics Core with PCI Interface, Virtual Media, Keyboard and KVMR Module[1]. Multiple vendors shipped the WPCM450 with Linux, making it feasible to build an open source replacement for the original BMC firmware[2][3][4]. 3rd party documentation and tools have been developed by neuschaefer and are available on github. The WPCM450 appears to be related to, or based on, the Winbond W90N745.
Flashing Firmware
To switch from the stock firmware to coreboot, external flashing is required.
