DESCRIPTION

     The sw is the Sun 4/100 on-board SCSI controller based on the NCR 5380
     chip, found only on Sun 4/100 workstations. The sw driver is actually im-
     plemented as part of the si(4) driver.

DEVICE FLAGS

     0x01
          Use DMA (polled)
     0x02
          Use DMA completion interrupts
     0x04
          Allow disconnect/reconnect

     The sw device flags may be OR'd together to enable any combination of the
     features listed above. If no flags are specified, the device will use
     polled DMA by default.
