 Jumper Setting
 ==============

 There are several, user configurable jumper options located on the
 PCBA.


 PIN 1 - Master/Slave
 --------------------
 1  CLOSED  Drive is MASTER (default)
    OPEN    Drive is SLAVE

 When pin 1 installed, the drive will respond as drive #1. When
 removed, the drive will respond as drive #2. If you have a slave
 drive, there must be a master, otherwise your system will hang.


 PIN 2 - PDIAG
 -------------
 2  CLOSED  Active Low

 PDIAG - This signal is used to signify to a master drive that the
 slave drive has passed its internal diagnostics, and is ready for
 operation. The CAM specification call for this signal to be active
 high, however, the defactor standard is for this line to be active
 low. When the PDIAG jumper is installed, it is active low.


 PIN 3 - Reserved
 ----------------
 Spare - This pin is reserved for future requirements.


 PIN 4 - IOCHRDY
 ---------------
 4  CLOSED  IOCHRDY is available

 IOCHRDY - This signal is used to extend the IOR and IOW phases of
 data transfer, thereby slowing the system transfer speed to match the
 drive's maximum buffer rate. This allows a drive of any buffer speed
 to run in any high speed system. When installed, IOCHRDY is
 available.


 PIN 5 - DACK
 ------------
 DACK - This signal is sent by the Host to initiate a DMA transfer
 once the drive has activated its DRQ signal.


 PIN 6 - DREQ
 ------------
 This signal is sent by the drive to indicate that it has data ready
 to send.
