NAME

vsMVME328, MVME328S and MVME328XT high performance SCSI controller

SYNOPSIS

vs0 at vmes0 addr 0xffff9000 ipl 2
vs1 at vmes0 addr 0xffff9800 ipl 2
vs2 at vmes0 addr 0xffff4800 ipl 2
vs3 at vmes0 addr 0xffff5800 ipl 2
vs4 at vmes0 addr 0xffff7000 ipl 2
vs5 at vmes0 addr 0xffff7800 ipl 2

DESCRIPTION

The vs provides access to the Interphase 4210 ‘Jaguar’, 4220 and 4220W ‘Cougar’, also sold as the Motorola MVME328, MVME328S and MVME328XT VME boards. Depending on the version, these boards provide up to two single-ended or differential, narrow or wide SCSI interfaces. Dual-channel boards do not necessarily have channels of the same type. On ‘Jaguar’ boards, the vs driver cannot report whether a channel is single-ended or differential. It is recommended to be very careful if the type of the channel is not known with certitude.

MVME328 channel configuration

The following table lists the channel configuration for Motorola MVME328 boards.
Model Number Channel 0 Channel 1
MVME328-1 Single-ended Missing
MVME328-2 Single-ended Single-ended
MVME328-3 Differential Missing
MVME328-4 Differential Differential

MVME328S channel configuration

The following table lists the channel configuration for Motorola MVME328S boards.
Model Number Channel 0 Channel 1
MVME328S-1 Single-ended Missing
MVME328S-2 Single-ended Single-ended
MVME328S-4 Differential Differential
MVME328S-5 Differential Single-ended

HARDWARE CONFIGURATION

The card's base address (matching the addr locator on the configuration line) is defined through a set of jumpers on the card.

MVME328, MVME328S and Interphase 4210 jumper configuration

The card address is controlled with nine jumpers, labeled “JB1” on the board, near the fuse in a corner of the card. They are contiguous to the “JA7” single jumper and “JA8” dual jumper, located immediately to the left of the “JB1” block.
The only supported configurations are:
JB1 Address Configuration
___X_XX__ 0xffff9000 1st board
_____XX__ 0xffff9800 2nd board
____XX_X_ 0xffff4800 3rd board
_____X_X_ 0xffff5800 4th board
___X___X_ 0xffff7000 5th board
_______X_ 0xffff7800 6th board

MVME328XT and Interphase 4220 and 4220W jumper configuration

The card address is controlled with two sets of eleven jumpers – which label will depend on the card model and artwork revision. These jumpers are located between the two VME P1 and P2 connectors. With the card oriented so that the VME connectors are at the bottom, the bottom row of eleven jumpers should have the leftmost jumper set and the ten rightmost jumpers open.
The only supported configurations for the top row are:
Jumpers Address Configuration
___X_XX____ 0xffff9000 1st board
_____XX____ 0xffff9800 2nd board
____XX_X___ 0xffff4800 3rd board
_____X_X___ 0xffff5800 4th board
___X___X___ 0xffff7000 5th board
_______X___ 0xffff7800 6th board

BUGS

The daughterboard providing access to the second SCSI channel does not work under OpenBSD if the first SCSI channel is empty.
