SCSI Setup
SCSI is the abbreviation for Small Computer System Interface.
The onboard ultra-wide SCSI controller (host adapter) is the interface between the
internal bus (PCI bus) and devices with SCSI interfaces (SCSI devices).
The onboard ultra-wide SCSI controller is a PCI chip which uses Bus Master
technology. This allows your SCSI controller to independently manage data
transfer between your SCSI peripherals and the computer system memory, without
requiring the involvement of your computer system CPU (Central Processing Unit).
All the information you require to install the SCSI Utility Software (e. g. drivers for
MS-DOS, Windows 3.x) is contained in the User Guide for the SCSI Utility
Software EZ-SCSI.
Details of how you install and operate your SCSI device may be found in the
associated Manual.
Setting SCSI addresses (IDs)
Each device which is connected to the ultra-wide SCSI controller must be set to a
separate SCSI address (ID 0 through ID 15).
The ultra-wide SCSI controller has ID 7. ID 7 has the highest priority, SCSI-ID 0
has the lowest. The priority of the remaining IDs, in descending order, is 15 to 8.
Ensure that each SCSI device is assigned it's own address.
²
Details how you set the SCSI address of your SCSI devices may be found in the
associated manual.

Connecting SCSI devices SCSI Setup
Connecting SCSI devices
SCSI devices and controllers are connected together via a common cable (SCSI
bus).
The termination (terminating resistors) must be enabled (or installed) on the last
device connected to the SCSI cable. The termination must be disabled (or
removed) from all other SCSI devices.
How you activate or deactivate the termination of the SCSI devices, see
description of your SCSI devices.
The system board provides the

means of the SCSI cable.
Only single-ended SCSI devices may be linked to the ultra-wide SCSI

controller. Most SCSI devices meet this requirement. If you are in any
doubt, contact your sales office or customer service.
How you install internal devices in the system unit and connect them to the power
supply is described in the Operating Manual or Technical Manual for your device
in the chapter "System unit" (paragraph "Installing a disk drive").

The following hints are only for the connectors at the onboard ultra-wide SCSI

Connectors and cables
The connector of the ultra-wide SCSI controller is 68pin.
The connector of 8-bit SCSI devices is 50pin; the connector of 16-bit SCSI devices
is 68pin.
If you want to connect 8-bit SCSI devices to the ultra-wide SCSI controller you
need an adapter (from 68pin to 50pin).
If you want to operate an 8-bit SCSI device as the last device on a SCSI line you
need an adapter (from 68pin to 50pin) with high-byte termination.

SCSI Setup
The BIOS of the ultra-wide SCSI controller includes a menu-driven

If an SCSI-BIOS error message appears or problems arise with SCSI

devices, please refer to the chapter entitled "Eliminating errors on the
SCSI controller" and "SCSI BIOS messages".
You may find further information in the documentation of your SCSI
device.

Enable disconnection
SCSI devices can release the SCSI bus during command execution with this
function. A typical example of this is a tape device that has no need to access the
SCSI bus during rewinding and can be "disconnected" from the SCSI bus for this

You can disable the function if you have only connected one SCSI device. In this
case, disconnection improves performance.

Send Start Unit Command
If the function is enabled, SCSI devices which support it are only started when
they receive the "Start-Unit" command from the SCSI BIOS. This allows the SCSI
devices to be activated consecutively. This is used if your system power supply is
too weak to start several drives simultaneously or for preventing switchon current
peaks.
You may have to make settings on your SCSI devices to enable support for this
function (see the documentation for the SCSI devices).

SCSI device is accessed by the SCSI BIOS and is assigned a drive identifier. A
message is displayed on the screen.

The SCSI device is not accessed by the SCSI BIOS.
This function should be set to No for drives which you know will never be

used as the boot drive (e.g. DAT drives). This saves time during system
startup.

Extended BIOS Translation for DOS Drives > 1Gbyte
Enabling this option allows drives of up to 8 Gbyte capacity (2 Gbyte/partition) to
be supported under MS-DOS 5.0 or higher. The SCSI BIOS must be enabled.
In earlier days, it was only possible to use drives with a capacity of up to 1 Gbyte
under MS-DOS 5.0.

Only the removable-media drive designated as the boot device is
treated as a hard disk (default setting).
All removable-media drives supported by the BIOS are treated as
hard disk drives.
No removable-media drives are treated as hard disk drives. In this
situation, software drivers are needed because the drives are not
controlled by the BIOS.
If a removable-media device is controlled by the SCSI controller BIOS, do
not remove the media while the system is switched on.
Drives up to 8 Gbytes can be used under MS-DOS 5.0 (default
entry).
Drives up to 1 Gbyte can be used under MS-DOS 5.0.
Back up the data on your large capacity drive before enabling the option.
After enabling this option, the drive must be re-partitioned and high-level
formatted with the DOS

Eliminating errors on the SCSI controller SCSI Setup
Eliminating errors on the SCSI controller
Most problems with the onboard ultra-wide SCSI controller occur when SCSI
devices are prepared (e.g. termination) and connected to the SCSI bus. Check the
following points if you have problems with the ultra-wide SCSI controller or the
connected SCSI devices:
Are all SCSI devices supplied with power?
•
Are the SCSI and power cables connected correctly on the SCSI device?
•
Is the SCSI cable connected correctly to the system board?
•
Has each SCSI device and the onboard SCSI controller been set to a different
•
SCSI ID?
Are the SCSI devices and the onboard SCSI controller correctly terminated?
•
Is the SCSI controller activated in the system BIOS (
•
Is parity checking either enabled or disabled on all SCSI devices on the SCSI
•
bus?
BIOS Setup
)?
SCSI BIOS messages
The following messages can appear during system startup if you have enabled the
SCSI BIOS:
Device connected, but not ready
The SCSI device connected to the ultra-wide SCSI controller is not ready (for
example because the drive motor for hard disks does not rotate). Set
to
Start Unit Command
the message still appears, check the settings required for the SCSI device in
its documentation.
Start unit request failed
The SCSI BIOS could not issue a start unit command to the SCSI device. Call
the
SCSI Setup
Time-out failure during ...
A timeout has occurred. Check the SCSI bus termination. Remove the SCSI
cable from the ultra-wide SCSI controller and restart the system. If system
startup is successful, check the SCSI cable. One of the SCSI devices may be
defective. Check the SCSI devices.
