# X11 LGA1151 series

The [Supermicro X11 LGA1151 series] are mostly the same boards with some minor differences in
internal and external interfaces like available PCIe slots, NICs (1 GbE, 10 GbE), IPMI, RAID
Controller etc.

## Supported boards

```{toctree}
:maxdepth: 1

X11SSH-TF <x11ssh-tf/x11ssh-tf.md>
X11SSH-F/LN4F <x11ssh-f/x11ssh-f.md>
X11SSM-F <x11ssm-f/x11ssm-f.md>
X11SSW-F <x11ssw-f/x11ssw-f.md>
```

## Required proprietary blobs

- [Intel FSP2.0]
- Intel ME

## De-blobbing

- [Intel FSP2.0] can not be removed as long as there is no free replacement
- Intel ME can be cleaned using me_cleaner (~4.5 MiB more free space)
- Intel Ethernet Controller Firmware can be removed when it's extended functionality is not
  needed. For more details refer to the respective datasheet (e.g 333016-008 for I210).
- Boards with [AST2400] BMC/IPMI: Firmware can be replaced by [OpenBMC]

## Flashing coreboot

Look at the [flashing tutorial] and the board-specific section.

## Known issues

These issues apply to all boards. Have a look at the board-specific issues, too.

- MRC caching does not work on cold boot with Intel SPS (see [Intel FSP2.0])

## ToDo

- Fix issues above
- Fix issues in board specific sections
- Add more boards! :-)
