NAME

vsbic — MVME327A SCSI and floppy controller

SYNOPSIS

vsbic0 at vmes0 addr 0xffffa600 ipl 2
vsbic1 at vmes0 addr 0xffffa700 ipl 2

DESCRIPTION

The vsbic driver supports the SCSI interface of the Motorola MVME327A SCSI 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 connectors at the top, the supported configurations are:

SEE ALSO

cd(4), ch(4), intro(4), scsi(4), sd(4), st(4), uk(4), vme(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.
