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

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