DESCRIPTION
     The vs provides access to the MVME328S family of SCSI VME I/O boards.
     Depending on the version, it provides a single or dual channel single-
     ended SCSI interface.  It is attached to the VME bus of the system, con-
     trolled by the vme(4) VMEchip2 interface chip.  Several types of both in-
     ternal and external connectors are provided, also depending on the ver-
     sion of the MVME328S.

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

BUGS
     The daughterboard providing access to the second SCSI channel is current-
     ly not supported by OpenBSD.
