Supermicro X11SSM-F

This section details how to run coreboot on the Supermicro X11SSM-F.

Flashing coreboot

The board can be flashed externally. FTDI FT2232H and FT232H based programmers worked. For this, one needs to add a diode between VCC and the flash chip. The flash IC MX25L12873F can be found near PCH PCIe Slot 4.

Flashing is also possible through the BMC web interface, when a valid license was entered.

BMC (IPMI)

This board has an ASPEED AST2400, which has BMC/IPMI functionality. The BMC firmware resides in a 32 MiB SOIC-16 chip in the corner of the mainboard near the PCH PCIe Slot 4. This chip is a MX25L25635F.

Disabling LAN firmware

To disable the proprietary LAN firmware, the undocumented jumper J6 can be set to 2-3.

Tested and working

  • GRUB2 payload with Debian testing and kernel 5.2
  • ECC ram (Linux' ie31200 driver works)
  • USB ports
  • Ethernet
  • SATA ports
  • RS232 external
  • PCIe slots
  • BMC (IPMI)
  • VGA on Aspeed
  • TPM on TPM expansion header

Known issues

  • See general issue section
  • LNXTHERM missing
  • S3 resume not working
