VSBIC(4)             OpenBSD Programmer's Manual (MVME68K)            VSBIC(4)

NAME
     vsbic - MVME327A SCSI and floppy controller

SYNOPSIS
     vsbic* at vmes0 addr 0xffffa600 ipl 2 vec 0x8c
     vsbic* at vmes0 addr 0xffffa700 ipl 2 vec 0x8d
     scsibus* at vsbic?

DESCRIPTION
     The vsbic driver supports the SCSI interface of the Motorola MVME327A SC-
     SI and floppy VME controller.  The WD33C93 SCSI controller found on this
     board is not directly accessible; instead, the vsbic driver runs SCSI
     commands through the MVME327A firmware interface.

HARDWARE CONFIGURATION
     The card's base address (matching the addr locator on the configuration
     line) is defined through a block of eight jumpers, labeled ``J5'' on the
     board, near its center.

     With the card oriented with its faceplate at the bottom and the VME con-
     nectors at the top, the supported configurations are:

           J5          Address       Configuration
           _X_XX__X    0xffffa600    1st board
           _X_XX___    0xffffa700    2nd board

SEE ALSO
     cd(4), ch(4), intro(4), scsi(4), sd(4), ss(4), st(4), uk(4)

BUGS
     Due to firmware limitations, SCSI commands using command blocks larger
     than 12 bytes are not supported.  Therefore, only the first 2TB of SCSI
     disks are accessible.
