The Minnowboard turbot is a Intel Atom based SBC

### Power control
The board can be powered on/off via a DC power jack:

### Low-level boot control
The board has a 6 pin serial header between the sata port and the microsd

*
2: CTS
*
3: VCC (3.3v)

[
mouser
](

)
Serial port settings: 115200 8N1
#### Network connectivity
Standard ethernet jack; nothing to see here.
### Bootloader
As an intel system the minnowboard comes with a UEFI bios installed, which
is capable of PXE booting. The recommended way of loading a bootloader is via
this mechanism e.g. grub, which lava can further drive.
Notes on how to build a suitable grub can be found in
[
the apertis setup guide
](

)
### Health checks
*
Standard x86
\_
64 Linux kernel can be used for healthchecks
### Lab notes and trouble shooting
Insert SD cards in the SD card slot for testing.
