J,

There are four switches, from left to right, switch 1 enables DMA
when down, disables DMA when up.  If you have more than 4MB RAM
in the expansion slot of a IIgs you will have to have switch 1 up.

The other three switches set the SCSI ID of the card.  All down
is zero and all up is 7.  It is a binary representation so
up down up would be 5, down up down would be 2, down up up
would be 3 and so on.

An ID setting of 2, I believe, institutes a delay to let devices
come on line.
