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;
vsbic driver runs SCSI commands through
the MVME327A firmware interface.
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:
cd(4), ch(4), intro(4), scsi(4), sd(4), st(4), uk(4)
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.
