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.
Flash Chip Location
The flash chip is located above the circular CMOS battery slot.
Flash Chip Orientation
The circle marking the location of pin 1 is highlighted red in the above image. The circle is a subtle indentation on the chip that can be seen with the aid of a flashlight.
Flashing Example
A CH341a programmer can be used to flash coreboot onto the H8SCM.
