VSBIC(4) OpenBSD Programmer's Manual (MVME68k) VSBIC(4)NAMEvsbic - 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
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:
J5 Address Configuration
_X_XX__X 0xffffa600 1st board
_X_XX___ 0xffffa700 2nd board
SEE ALSOcd(4), ch(4), intro(4), scsi(4), sd(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.
