Try playing with DIP -switches.
-Turn switch no.1 to OFF position, which disables autoboot function.
-Second is for LUN setting (OFF - one drive at each address, ON - multiple drives at each address) .
-Third is for time out setting ( OFF - Short wait period for drive / parity check enabled. ON - Long wait period for drive / parity check disabled).
-Fourth switch isn't used at all.
