DESCRIPTION
     The vs provides access to the Interphase 4210 `Jaguar', 4220 and 4220W
     `Cougar', also sold as the Motorola MVME328, MVME328S and MVME328XT VME
     boards.  Depending on the version, these boards provide up to two single-
     ended or differential, narrow or wide SCSI interfaces.  Dual-channel
     boards do not necessarily have channels of the same type.  On `Jaguar'
     boards, the vs driver cannot report whether a channel is single-ended or
     differential.  It is recommended to be very careful if the type of the
     channel is not known with certitude.

     boards.

HARDWARE CONFIGURATION
     The card's base address (matching the addr locator on the configuration
     line) is defined through a set of jumpers on the card.

   MVME328, MVME328S and Interphase 4210 jumper configuration
     The card address is controlled with nine jumpers, labeled ``JB1'' on the
     board, near the fuse in a corner of the card.  They are contiguous to the
     ``JA7'' single jumper and ``JA8'' dual jumper, located immediately to the
     left of the ``JB1'' block.

     The only supported configurations are:

           JB1          Address       Configuration
           ___X_XX__    0xffff9000    1st board
           _____XX__    0xffff9800    2nd board
           ____XX_X_    0xffff4800    3rd board
           _____X_X_    0xffff5800    4th board
           ___X___X_    0xffff7000    5th board
           _______X_    0xffff7800    6th board

   MVME328XT and Interphase 4220 and 4220W jumper configuration
     The card address is controlled with two sets of eleven jumpers - which
     label will depend on the card model and artwork revision.  These jumpers
     are located between the two VME P1 and P2 connectors.  With the card ori-
     ented so that the VME connectors are at the bottom, the bottom row of
     eleven jumpers should have the leftmost jumper set and the ten rightmost
     jumpers open.

     The only supported configurations for the top row are:

           Jumpers        Address       Configuration
           ___X_XX____    0xffff9000    1st board
           _____XX____    0xffff9800    2nd board
           ____XX_X___    0xffff4800    3rd board
           _____X_X___    0xffff5800    4th board
           ___X___X___    0xffff7000    5th board
           _______X___    0xffff7800    6th board

BUGS
     The daughterboard providing access to the second SCSI channel does not
     work under OpenBSD if the first SCSI channel is empty.
