# 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
- [X11SSH-TF](x11ssh-tf/x11ssh-tf.md)
- [X11SSH-F/LN4F](x11ssh-f/x11ssh-f.md)
- [X11SSM-F](x11ssm-f/x11ssm-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! :-)
