The MinnowBoard Max Platform guide can be found:
Intel® Atom™ Processor E3800 Product Family MinnowBoard MAX: Platform Guide
Page 10 shows six-pin header J4 to be able to connect to a terminal.
The following text is wrong:
Pin 1 is on the right in Figure 3, furthest away from the SATA port.
It should be:
Pin 1 is on the left in Figure 3, closest to the SATA port.
Based on this error, also the picture (reference Figure 5) on page 12 should be updated.
The black wire (GND pin 1) should be assembled closest to the SATA connector.
For explanation, see below the actual screen dump of the layout of the board.
