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" motherboard jumper can be used to disable the onboard BMC, effectively turning the H8SCM-F into the H8SCM.

Onboard BMC

The Nuvoton WPCM450, or simply the WPCM450, is a BMC chip used in the SuperMicro family of boards containing the "-F" suffix. Multiple vendors shipped the WPCM450 with Linux, making it feasible to build an open source replacement for the original BMC firmware[1][2][3]. 3rd party documentation and tools have been developed by neuschaefer and are available on github.

Flashing Firmware

To switch from the stock firmware to coreboot, external flashing is required.
