This section details how to run coreboot on the Supermicro X11SSH-F.
The board can be flashed externally. STM32-based programmers worked.
The flash IC “W25Q128.V” (detected by flashrom) can be found near PCH PCIe Slot 4. It is sometime socketed, and covered by a sticker, hindering the observation of its precise model.
It can be programmed in-system with a clip like pomona 5250.
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.
If an IGD is integrated with CPU, it will be enabled on this board. Though there is no video output for it (The onboard VGA port is connected to BMC), it is said to be capable of being used for compute tasks, or for offloading graphics rendering via “muxless” [vga_witcheroo].
Tested and working¶
- SeaBIOS payload to boot Kali Linux live USB
- ECC ram (Linux’ ie31200 driver works)
- Integrated graphics device available without output
- USB ports
- SATA ports
- RS232 external
- PCIe slots
- BMC (IPMI)
- VGA on Aspeed
- TPM on TPM expansion header
- See general issue section
- S3 resume not working (vendor and coreboot)
- SeaBIOS cannot make use of VGA on Aspeed (even if IGD is disabled)
- Fix known issues
- Testing other payloads
