VS(4)

NAME
vs - MVME328, MVME328S and MVME328XT high performance SCSI controller

SYNOPSIS
vs* at vmes0 addr 0xffff9000 ipl 2 vec 0x80
vs* at vmes0 addr 0xffff9800 ipl 2 vec 0x82
vs* at vmes0 addr 0xffff4800 ipl 2 vec 0x84
vs* at vmes0 addr 0xffff5800 ipl 2 vec 0x86
vs* at vmes0 addr 0xffff7000 ipl 2 vec 0x88
vs* at vmes0 addr 0xffff7800 ipl 2 vec 0x8a

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.
