MVME328, MVME328S and MVME328XT high
performance SCSI controller

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 |

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.
