Check the schematic Page 13. There is a table showing where the jumpers go to affect the booting sequence. All you have to do is solder a wire into those holes to change the setting. For SATA you just need to install one wire in J3 position 1-2 and remove R444. The lines in read show the default which is set by the resistors onboard.

Is there a way to boot from an external USB hard drive? or 2. Can someone provide more detail directions on switching boot sequence to boot directly from eSATA? The reference manual is very vague on this. You need to unsolder and resolder resistors to act as jumpers? There are perforated holes in the circuit board where the resistors and jumpers are supposed to be. Are the resistors supplied? Are they on the board? If so where are they? What are their values in Ohms? How are the perforations on the board numbered 1-3 from left to right or right to left? This needs to be much more detailed. Why would you design a board that make switching the boot sequence so difficult? How about just putting in some removable jumpers! Any detailed help and direction would be appreciated.
