DESCRIPTION    [Toc]    [Back]

     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 singleended
 SCSI interface.  It is attached to the VME bus of  the
system, controlled
  by  the  vme(4)  VMEchip2  interface chip.  Several
types of both internal
 and external connectors are provided, also  depending
on the version
 of the MVME328S.

HARDWARE CONFIGURATION    [Toc]    [Back]

     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
