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
driver runs SCSI commands through the
MVME327A firmware interface.
The card's base address (matching the addr
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:
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
