This section details how to run coreboot on the [Supermicro X11SSH-F] or [Supermicro X11SSH-LN4F].

## Flashing coreboot
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
## 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].
|
|
|
|
|
|
|
|
|
|
## IGD
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
- Ethernet
|
|
|
|
|
- SATA ports
|
|
|
|
|
- RS232 external
|
|
|
|
|
- PCIe slots
|
|
|
|
|
- BMC (IPMI)
|
|
|
|
|
- VGA on Aspeed
|
|
|
|
|
- TPM on TPM expansion header
|
|
|
|
|
|
|
|
|
|
## Known issues
|
|
|
|
|
|
|
|
|
|
- See general issue section
|
|
|
|
|
- S3 resume not working (vendor and coreboot)
|
|
|
|
|
- SeaBIOS cannot make use of VGA on Aspeed (even if IGD is disabled)

## Difference between X11SSH-F and X11SSH-LN4F
|
|
|
|
|
|
|
|
|
|
The PCB is identical. The X11SSH-F has 2 NICs, the X11SSH-LN4F has 4 NICs.
|
|
|
|
|
So the X11SSH-F just doesn't have 2 NICs populated.

|
|
|
|
|
|
|
|
- Fix known issues
|
|
|
|
