1.9.3 Watchdog timer output (J2)
The AIMB-740-B/741-B contains a watchdog timer that will reset the
CPU or send a signal to IRQ11 in the event the CPU stops processing.
This feature means the AIMB-740-B/741-B will recover from a software
failure or an EMI problem. The J2 jumper settings control the outcome of
what the computer will do in the event the watchdog timer is tripped.
1.9.4 Riser card selection (J3 & J4, only for AIMB-740-B)
The AIMB-740-B contains a riser card selection that enables the riser
card function. While using 2U riser card, you should close pin 1 and pin 2
of J3 and J4 to activate the PCI slots on the riser card.
