# Supermicro X11SSH-TF

This section details how to run coreboot on the [Supermicro X11SSH-TF].

## Flashing coreboot

The board can be flashed externally using *some* programmers. The CH341 was found working, while
Dediprog didn't detect the chip.

The flash IC can be found between the two PCIe slots near the southbridge:

## 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 [AST2400]. This chip is an
[MX25L25635F].

## Tested and working

- USB ports
- Ethernet
- SATA ports
- RS232 external
- ECC DRAM detection
- PCIe slots
- M.2 2280 NVMe slot
- BMC (IPMI)
- VGA on Aspeed
- TPM on TPM expansion header
