Dear port-alpha:

I've a QLogic ISP1020 SCSI controller, but no documentation for it. 
Could someone verify what its four jumpers are for, please?

There are four, just to the right of the 68-pin internal connector, 
arranged in a square.  I've attempted to show them and the silk 
screening on the PCB beside them below:


             TERM DIS

               1  2
         HIGH  +  +   JP1

          LOW  +  +
               3  4



This controller came in a PWS 500.  When it arrived jumpers 1 and 2 
were open and 3 and 4 were connected.
