New information:

1)  I am able to restore operation of the Metis board by using a USB- 
Blaster cable (ASIC Terasic Blaster cable) by attaching the blaster  
cable onto the JTAG header and targeting the Metis.sof file to load  
code into the Metis FPGA directly through the JTAG header with the  
Quartus II Programmer in JTAG mode and with JP1 in place on the Metis  
board.

2)  After restoring operation, the board will operate normally if you  
remove JP1 while the board is running until the Metis board is power  
cycled.  Upon a power cycling of the Atlas bus the Metis board does  
not come up (no status LEDs lit, only the four power supply LEDs come  
on).

This Metis  board is unable to come up in a normal manner once power  
has been removed from it.

Hints?
