The PCL-843 can be set to Mode 0 or Mode 1. This option is de-
signed to compensate for motherboard ISA bus timing controls. For
the majority of systems, select Mode 0 (default). Mode 1 is for older
systems utilizing C&T chipsets, IBM 286 (or compatible) systems or
Compaq 286 portable systems. This is done via pins 1 and 2 on a four
position jumper, JP4, as shown below:
