The ASUS PCI-SIU2 Host Adapter

The ASUS® PCI-SIU2™ is a high-performance Ultra2 (Low Voltage Differen­tial) PCI bus master host adapter which provides the interface between the
SCSI bus and the PCI local bus. The PCI-SIU2 supports 32-bit data transfers
across the high bandwidth PCI bus at speeds up to 133 Mbytes per second.
The advanced Integrated Scatter/Gather Engine (ISGE™) reduces the command
overhead time enhancing the overall system response, thus providing excep­tional performance for the PCI-SIU2.

An on-board utility program is designed into the host adapter to simplify SCSI
bus set-up. The SmartSCSI
of the PCI-SIU2 into most platforms and with many operating systems. The
SmartSCSI utility will enhance the installation procedure of the host adapter
and allow for complete self-integration in those systems that implement the
current plug and play standards. The PCI-SIU2 complies with plug and play
applications on systems using PCI bus standards.

Host Adapter and the SCSI Bus

The PCI-SIU2 is a bus mastering host adapter which works with the host com­puter to provide control for the SCSI bus. By daisy chaining peripheral de­vices together, up to 15 SCSI devices can be connected to the PCI-SIU2. The
host adapter can be placed in any standard PCI slot on the bus.

SCSI Bus Preparation

Peripheral devices attached to the SCSI bus can either be an internal or exter­nal device. Each peripheral has a specific device ID, commonly referred to as
a “SCSI ID.” The SCSI ID determines priority when two or more devices are
trying to use the SCSI bus at the same time. No two devices can have the same
ID; the device ID uniquely defines the device to the SCSI bus. The PCI-SIU2
is preset to SCSI ID 7 and should not be changed. This gives it the highest
priority on the SCSI bus. Please refer to your peripheral documentation to
determine switch or jumper settings for SCSI ID’s. Here are some general
guidelines for SCSI IDs:

• SCSI ID numbers don’t have to be sequential, as long as the PCI-SIU2

and each peripheral has a different number. For example, you can
have an internal SCSI peripheral with ID 0, and an external SCSI
periphera1 with ID 6. Gaps in the sequence of numbers don’t matter.

• For internal SCSI peripherals, the SCSI ID usually is set by configur-

ing a jumper on the peripheral.

• For external SCSI peripherals, the SCSI ID usually is set with a switch

on the back of the peripheral.

• SCSI ID 7 has the highest priority on the SCSI bus. The priority of the

remaining IDs, in descending order, is 6 to 0, 15 to 8.

• Most internal SCSI hard disk drives come from the factory preset for

SCSI ID 0.

ASUS PCI-SIU2 User’s Manual 13

2. Getting Started

• If you have 8-bit SCSI peripherals, they must use SCSI IDs 0, 1, 2, 3,
4, 5, or 6. SCSI ID 0 is recommended for the first SCSI hard disk drive.

• In Windows 95/98, you can use the Device Manager to view the SCSI
ID (and other details) assigned to each SCSI device installed.

• Through ASUS’s SmartSCSI, you can use the utility to view the SCSI
ID (and other details) assigned to each SCSI device installed.

SCSI Bus Termination

The SCSI bus structure has a length limitation as well as a requirement for
termination at each end of the SCSI cable. The cable is designed to connect in
a daisy chain fashion. No branching is permitted in the SCSI bus. The first
and last physical SCSI device on the SCSI bus must be terminated (see Ca­bling Examples). T o ensure reliable communication on the SCSI bus, the ends
of the SCSI bus must be properly terminated. This is accomplished when the
peripheral at the end of each cable, or the end of the cable itself, has a termina­tor installed (or enabled). The peripherals between the ends of each cable must
have its terminator removed (or disabled).

Since the method for terminating a SCSI peripheral can vary widely, refer to
the peripheral’s documentation for instructions on how to enable or disable
termination. Here are some general guidelines for termination:

• Internal Ultra2 peripherals are set at the factory with termination dis­abled and cannot be changed. Proper termination for internal Ultra2
peripherals is provided by the built-in terminator at the end of the Ul­tra2 internal SCSI cable.

• Termination on internal SCSI peripherals usually is controlled by manu­ally setting a jumper or a switch on the peripheral, or by physically
removing or installing one or more resistor modules on the peripheral.

• Termination on external SCSI peripherals is usually controlled by in­stalling or removing a SCSI terminator . On some external peripherals,
termination is controlled by setting a switch on the back of the drive.

• By default, termination on the PCI-SIU2 is automatic (the preferred
method). To manually set termination on the PCI-SIU2, see Host
Adapter Setup in Chapter 4.

• Most non Ultra2 SCSI peripherals come from the factory with termi­nation enabled.

2. Getting Started

Mixing UltraSCSI &U2 (LVD) SCSI Devices

The PCI-SIU2 supports legacy drives. However, in order to maximize perfor ­mance of SCSI I/O’ s it is recommended to only connect LVD (Ultra2) devices
to the PCI-SIU2. If a legacy device is attached to the PCI-SIU2, the devices
attached will be switched to SE (Single-Ended) mode. Then all SE SCSI pa­rameters (# of devices, cable length, cable impedence) will become in effect.

2. Getting Started

PCI-SIU2’ s SCSI termination can be set to auto-termination or programmable
mode via the SmartSCSI Setup Utility. This feature allows the operator to
switch the auto-termination On or Off. If auto-termination is switched Off, the
operator can manually program termination for the host adapter. There are
several ways to manually control terminating the host adapter on the SCSI bus.

Installation Basics

The internal cable permits connection of multiple internal devices. SCSI de­vices that are connected to the internal connector are installed inside the host
computer enclosure. The external connector is accesible through the D-shell
connector at the back of the host system and is designed to connect devices
outside the host system enclosure.

The PCI-SIU2 has one internal 68-pin high-density connector and one exter­nal 68-pin high-density connector for a combined support for 15 SCSI de­vices. The two connectors are the same except for the screw holes on the sides
of the external connector .

High Density External...........

High Density Internal............

FIGURE 5 | Connector Details

NOTE:
Attaching UltraWide or UltraSCSI peripherals to the Ultra2 SCSI seg­ment of the SCSI bus causes the Ultra2 SCSI segment and any attached
peripherals to drop to UltraSCSI performance levels (40 MBytes/sec).
Attaching only Ultra2 peripherals to the PCI-SIU2 ensures that all pe­ripherals on the Ultra2 segment will perform at Ultra2 performance
levels (80 Mbytes/sec).

ASUS PCI-SIU2 User’s Manual 17

3. Hardware Installation

Installing the PCI-SIU2 Host Adapter

1 Power down the host computer and all peripherals

Remove the cover from the host system. You may need to refer to the
system manual for cover removal. If necessary, identify the PCI sock­ets inside the host system with the aid of the system documentation.

2 Use static electricity discharge precautions

Remove possible static discharge potential from any objects that the
host adapter may come in contact with before installation. This can be
accomplished by touching a bare metal chassis rail after you have turned
off the power.

3 Inserting the host adapter

Orient the host adapter for installation so that the external connector is
facing the back of the system unit and align the card with the PCI
connector on the system unit (see FIGURE 6). Holding the adapter by
the mounting bracket and the card edge, match up the card edge con­nector with the PCI host computer socket and insert the card into the
socket. Once the connector is in the PCI expansion slot socket tighten
the mounting bracket screw to secure the card in place.

3. Hardware Installation

4a Installation of internal SCSI devices

A total of 15 SCSI peripherals can be connected to the PCI-SIU2. One
internal 68-pin high density Ultra2 cable is included (see FIGURE 7).
This cable is used to connect internal target devices. The internal cable
is made with multiple connectors attached and used to daisy chain the
host adapters to two or more target devices. The connector on the host
adapter is keyed for proper orientation and insertion. Plug the long end
of the cable to the host adapter and the remaining connectors to the
target SCSI devices. It is important to use the cable with the termina­tion on one end of the cable towards the target device side. The cable
is limited to a total lenghth of 12 meters including external cabling.
Installation of internal cable must be performed before replacing the
cover.

ASUS PCI-SIU2 User’s Manual 19

3. Hardware Installation

4b Installation of external SCSI devices

Use the 68-pin external Ultra2 SCSI connector to connect your exter­nal Ultra2 peripherals. Ultra2 external cables are not included in the
kit. Installation of external SCSI cables can be performed after the
cover has been closed. The cable is limited in length to a total of 12
meters including any internal cabling. The external cable can be daisy
chained to include up to 15 devices with the host adapter in combina­tion with internal devices. The external cable is designed to be in­serted only one way, requiring termination at the end peripheral de­vice (FIGURE 9).

FIGURE 9 | External cable connection

NOTE:
We recommend keeping your Ultra2 peripherals seperate from your
non-Ultra2 peripherals. Connecting a non-Ultra2 peripheral to the
Ultra2 SCSI connector forces the Ultra2 SCSI segment and any at­tached peripherals to drop down to UltraSCSI performance levels (40
MBytes/sec).

T o increase the reliability of the cabling being used with the host adapter, it is
recommended that the following guidelines be observed:

• SCSI-1 – Cabling up to 6 meters (20 feet)

• UltraSCSI – Four devices, up to 3 meters (10 feet)

• UltraSCSI – Eight devices, up to 1.5 meters (5 feet)

• Ultra2 (point-to-point configuration) – Up to 25 meters (82 feet)

• Ultra2 (multiple interconnect config) – Up to 12 meters (39 feet)

• Impedance of the cable should be 120 (±8 ohms); Ultra2

• Impedance of the cable should be 90 (±8 ohms); UltraSCSI & FastSCSI.

• Use high quality shielded connectors for external devices.

6 Close the cover on the host computer

Visually inspect the configuration you have installed to verify that all
cables have been inserted correctly. Close the cover on the host com­puter. The hardware installation for the host adapter is now complete.

7 Host computer configuration

Most computer manufacturers with a PCI bus automatically configure
the add on-card or host adapter I/O Port address, IRQ Setting and BIOS
address. If this is not the case with your computer system, you will
need to manually configure your system.

There are two means of configuring the PCI bus from the host com­puter system:

1. Setting jumpers on the host system motherboard.

2. Setting CMOS BIOS incorporated into the host system.
You will need to refer to the host computer system documentation to

complete PCI bus activation and setup.
If the host system will be using a SCSI device to provide system boot

capability, then the system CMOS drive type settings may need to be
changed. Under some conditions the system will expect the boot disk
to be an IDE drive. This must be changed in order to boot from a SCSI
device.

ASUS PCI-SIU2 User’s Manual 21

3. Hardware Installation

8 System startup

The newly installed SCSI bus is now ready to power up. Switch on
peripheral and host computer system power . The system monitor should
display the following information, but may vary, based on the system
BIOS manufacturer.

• The normal Power-On Self Test and memory test procedure.

• The host adapter sign on message including a list of attached SCSI
devices.

The list should match the peripheral devices attached to the bus. In most
cases the host computer system is now configured and ready for use.

Some situations will require that a low-level format be performed us­ing the host adapter SmartSCSI Setup Utility to initialize a SCSI disk
drive and lay the foundation for a bootable SCSI drive.

9 SmartSCSI Setup Utility

The SmartSCSI Setup Utility simplifies the SCSI installation process
by eliminating the need for opening the system to change system jump­ers and switch settings. All necessary host adapter functions are ac­cessible through the utility , simplifying customization for your system
needs. ASUS’ s SmartSCSI Setup Utility is divided into five segments
identified by: Scan Bus; Device Setup; Adapter Setup; BIOS Setup;
and Disk Utility. These program functions are accessible by typing
<CTRL><I> at the boot-up prompt when the message comes to view .

Hard Disk Drive Preparation

A new SCSI disk drive is normally low-level formatted at the factory to sim­plify installation. Every SCSI hard disk drive must be physically low-level
formatted, partitioned, and logically formatted before it can be used to store
data. SCSI hard disks are physically low-level formatted at the factory and do
not usually need to be formatted again.

If you connect a newer SCSI hard disk drive to your SCSI card, you must
partition and logically format the drive. For DOS and Windows (3.x and 95)
use the DOS Fdisk and Format commands (see your computer, DOS, and
Windows documentation). For other operating systems, see your operating
system documentation.

If you are booting from a SCSI hard disk drive, make sure the Hard Disk (or
Drives) setting in your computer’s CMOS setup program is set to None or No
Drives Installed, as is required for SCSI hard disk drives. See your computer
documentation for details.

3. Hardware Installation

If both SCSI and non-SCSI (for example, IDE) disk drives are installed, then
the non-SCSI disk drive is typically the boot drive. If your computer supports
BBS (BIOS Boot Specification), both SCSI and non-SCSI disk drives can
coexist and you can specify which drive to boot from. Refer to your computer
documentation for more information.

Low-level Format

A low-level format will erase any data that is stored on the target disk. Before
attempting to perform a low-level format be sure the data on the target disk
has been backed up. A low-level format can be achieved via the SmartSCSI
Setup Utility for PCI-SIU2.

The low level format sets the media to a state which is easily recognized by
the host adapter on the SCSI bus. Once this format is completed, you will
need to partition the drive. Refer to your operating system documentation for
further information on partitioning drives.

Multiple Initiators & Clustering

A multiple initiator environment is one in which the SCSI bus has two or more
host adapters. T o work in a cluster , the host adapters must perform properly in
such an environment by not resetting the bus without an explicit host com­mand, for example. ASUS’s host adapters are built for multi-initiator opera­tion and adhere strictly to the SCSI standard.

FIGURE 11 illustrates the principal components in a cluster’s I/O system. It
shows a simple cluster with two servers sharing access to online storage (the
basic model for Microsoft’s MSCS clusters). Both servers contain a host
adapter that provides access to the shared external I/O bus. Servers can share
disks or arrays attached to this shared I/O bus. The operating system controls
contention for disk access by using either a component called a distributed
lock manager (DLM) to resolve access conflicts or a shared-nothing model
that partitions disks and arrays, giving each server control over a subset of the
storage under normal circumstances. MSCS uses the shared-nothing approach.

Under some circumstances multiple initiators can be used on a single SCSI
bus. The bus is configured to have more than one host adapter inserted into at
least two distinctly different computer systems sharing peripheral devices. In
these circumstances, it is possible to have one of the two computer systems
turned off. Under these conditions,

3. Hardware Installation

the host adapter has a jumper that can be enabled (closed) to set the active on­board termination on all the time, regardless of whether power is applied or
not. The host adapter is shipped without the jumper installed and need not be
changed in most cases. Visually inspect the configuration you have installed
to verify that all cables have been inserted correctly.

ASUS PCI-SIU2 User’s Manual 25

4. Host Adapter Setup

Main Menu Options

SmartSCSI’s main menu provides five possible setup options for meeting your
system configuration:

Scan Bus

Choosing this option results in the host adapter utility to scan the SCSI bus to
determine peripheral devices attached to the host adapter . All device ID’ s are
displayed on the screen including SCSI ID’s without devices attached. This
allows for a better definition of location and priority on the SCSI bus.

• A device ID should only be changed if it conflicts with another device
address on the same bus. Refer to your peripheral documentation for
changing SCSI ID’s.

• The best ID for a bootable hard disk is SCSI ID-0.

Device Setup

Asynchronous T ransfer. Use this option to set the synchronous data transfer
mode. PCI-SIU2 will transfer data at a maximum rate of 80 MBytes per sec­ond in synchronous mode and a maximum rate of 10 Mbytes per second in
asynchronous mode. Use this option to set the synchronous data transfer mode.
The default setting for this option is for synchronous operation. (No)

Maximum Synchronous T ransfer Rate. This option determines the speed at
which data is moved across the SCSI cable. PCI-SIU2 has the option of run­ning from 80 MBytes per second in synchronous mode.

DOS Space > 1 GB. Using this option allows for single disk capacities to be
extended up to 8 GBytes (Yes). Please refer to the Troubleshooting Section
titled DOS Space > 1 GB for further information on this feature.

• (NO) DOS limits the number of cylinders per drive to 1024. The host
adapter defines head and sector usage to 64 heads and 32 sectors. This
format allows for maximum capacity of 1 gigabyte per disk storage.

• (YES) The upper limit can be extended from 1 GByte to 8 GBytes by
increasing the number of heads to 255 and number of sectors used per
track to 63. NOTE: This is a powerful option. Data can be lost by

changing settings.

26 ASUS PCI-SIU2 User’s Manual

4. Host Adapter Setup

Spin Up Disk Drive. This option is used to initiate motor spin-up for SCSI
disk drives. The host adapter BIOS can limit system power requirements dur­ing power-up. This is accomplished by signaling the device to start at delayed
intervals (default setting will be ‘No’).

Enable Disconnect. The host adapter uses this option to allow a device to
temporarily disconnect from the SCSI bus (referred to as disconnect/recon­nect). This allows the host adapter to perform other functions on the bus while
the device is temporarily disconnected. The device and the host adapter can
then reconnect when the bus is needed (default setting will be ‘Yes’).

Enable Wide Negotiation. This option determines whether the host adapter
initiates wide data transfer with the specified SCSI device. However, not all
SCSI devices can handle wide data transfer negotiations properly , which may
cause system failure. Certain old CD-ROM, CD-Recordable, and tape drives
cannot handle a Wide Transfer negotiation request from the PCI-SIU2 and
may fail to start the system. In such cases, use SmartSCSI to disable (NO
check) the W ide Negotiation setting for the SCSI ID of the anomalous device.

Adapter Setup

Host Adapter SCSI Bus ID. Used to change the adapter ’s SCSI ID on the
SCSI bus. The narrow host adapters provides eight ID’ s available numbered 0­7, with 7 having the highest priority (and ID-7 reserved for the host adapter).

Installation of multiple host adapters is permitted on the same SCSI bus. This
option allows the system to have more than one SCSI bus attached. Under
these conditions, SCSI ID’ s must be mutually exclusive.

SCSI T erminators. This option is used to set host adapter termination located
on the host adapter card. This option is also used to manually control termina­tion on the host adapter. The normal setting for this option is auto.

SCSI Parity Check ON. Select this option to enable or disable parity check­ing on the SCSI bus by the host adapter. The default setting for this option is
ON (Yes).

ASUS PCI-SIU2 User’s Manual 27

4. Host Adapter Setup

BIOS Setup

Enable Host Adapter BIOS. This option controls the host adapter usage of
SCSI disk I/O routines inside the host adapter BIOS. By disabling this option
you will eliminate the host adapter’s ability to utilize boot capabilities in PCI­SIU2. Setting this to “no” will also disable all subsequent features displayed
by this on-screen panel. The default setting will be on. (Yes)

Boot Device ID. This option selects which SCSI device will be the designated
boot device for the system. The default ID for this option is 0.

BIOS Support for Bootable CD-ROM. This option allows users to boot
from a bootable CD by replying with Yes at the prompt. Only one bootable
CD-ROM will be allowed at a time. The default setting will be off. (No)

BIOS Treat Removable Disks as Fixed Disk. This option is able to treat
removable disks as fixed disks. W ith this option selected you can run remov­able disk media without additional software drivers. The default setting will
be off. (No)

Disk Utility

These functions will be displayed when a device has been highlighted. Once a
menu has been pulled up, the host adapter will scan all devices and display all
necessary information. Selecting a device allows you to perform either of
these two following actions:

Verify Disk. This option will verify the media of a successfully formatted
device and verify that the drive is functioning properly. Verify will also iden­tify and flag any bad sectors on the disk so that during operation these flagged
sectors will not be used. If a bad sector is found you are given two options
shown below:

• Reassign will assign the flagged location to another sector on the disk.

• Skip will not reassign the flagged location.

Format Disk. Use this option to perform a low level disk format on the target
device. The format will erase all data resident on the targeted disk drive. Refer
to the section titled “Hard Drive Preparation” for additional information.

CAUTION: A low-level format destroys all data on the drive. Be

sure to back up your data before performing this op­eration. You cannot abort a low-level format once it
has started.

Overview

The ASUS ASPI driver will support extended SCSI command functions for
MS-DOS 3.30 or later. The on-board BIOS initialized during the power up
boot routine only supports MS-DOS hard disk operation. If peripherals other
than disks are used, such as CD-ROM or MO, the ASUS ASPI driver will need
to be installed in addition to ASUS CD-ROM and MO drivers.

Installation

The installation procedure guides you through the installation of the ASUS
DOS ASPI. The installation procedure described here requires some experi­ence in MS-DOS setup and administration. The device driver is transferred
from the PCI-SIU2 DRIVER DISK to the hard drive where it is automatically
initialized during the system boot routine.

The PCI-SIU2 DRIVER DISK contains one installation program that per-
form the same task.

Installing the ASPI drivers to an existing MS-DOS
system

The ASPI driver is found on the PCI-SIU2 DRIVER DISK . It is important
that the SCSI bus hardware, and operating system are installed correctly before
proceeding further . If you need help installing the MS-DOS operating system,
please refer to the MS-DOS manual before proceeding.

1. Turn on host system and boot into MS-DOS.

2. Insert the PCI-SIU2 DRIVER DISK into your floppy drive.

3. At the MS-DOS prompt, change to your active floppy drive (e.g.,
type A: <ENTER> ).

4. T ype DOSSETUP <ENTER> (A series of scr eens will guide you

through the installation of the ASPI device drivers).

ASPI CD-ROM Driver Command Line Options

INICD.SYS is a DOS device driver for supporting SCSI CD-ROM drives. It
is the interface between MSCDEX.EXE (supplied by Microsoft®) and the physi­cal CDROM drive. INICD.SYS is automatically loaded in the CONFIG.SYS
start up file by the ASUS DOSSETUP or SETUP programs. INICD.SYS re­quires that the ASUS ASPI Manager be loaded. INICD.SYS can be loaded
with either the DEVICE= or DEVICEHIGH= command. INICD.SYS can be
found on PCI-SIU2 DRIVER DISK. Below is a list of command line options
and examples.

/D: /d: This option is used to specify the name of the device driver. The

name specified must also be passed to MSCDEX.EXE on it’s
command line (Using the same /D: or /d: option). The name speci­fied must be 8 or less characters in length. Valid characters are
the A-Z, a-z, 0-9 and underscore. The name must start with a
letter.

Examples: /D:INICD001

/d:mscd001
/d:MYCD01

/T /t This option is used to specify a Time out value to be used when

sending commands to a CDROM drive. If a CDROM drive does
not respond to a command within the specified time out then the
command will be aborted and an appropriate error message will
be displayed. The time out value is specified in minutes. Valid
values are 1-9 and D or d. The D or d values are used to Disable
the time out mechanism. If the time out mechanism is disabled
then faulty hardware can lock up the system.

ASPI Disk Driver Command Line Options

INIDISK.SYS is a DOS block device driver for supporting SCSI fixed disks,
removable disks and MO devices. INIDISK.SYS is automatically loaded in
CONFIG.SYS start up file by the ASUS DOSSETUP or SETUP programs.
INIDISK.SYS requires that the ASUS ASPI Manager be loaded. INIDISK.SYS
can be loaded with either the DEVICE= or DEVICEHIGH= command.
INICD.SYS can be found on the PCI-SIU2 DRIVER DISK 1. Below is a list
of command line options and examples.

/R /r This option specifies the number of logical drives to reserve for

MO and removable disk devices. MO and removable disks me­dia are capable of being partitioned just like a fixed disk. For
every DOS partition on the media a logical DOS drive letter will
be available. INIDISK.SYS will support as many logical drives
as required (up to the maximum supported by DOS) based on the
partitioning of the media that is present when your system boots.
However, the media may be removed at any time and a new disk
may be inserted. The new disk may have more (or less) parti­tions then the original disk. The /R /r option is used to reserved
drive letters at start up in order to facilitate a disk change to a
disk with more partitions than the original disk present at boot
time. The value after the /R /r option determines how many drive
letters will be reserved on a device basis. For example, if the user
specifies a /R4 option and there are two removable devices at­tached to the SCSI bus, then a total of eight (8) drive letters will
be reserved.

/T /t This option is used to specify a Time out value to be used when

sending commands to a SCSI drive. If a SCSI drive does not
respond to a command within the specified time out then the com­mand will be aborted and an appropriate error message will be
displayed. The time out value is specified in minutes. Valid val­ues are 1-9 and D or d. The D or d values are used to Disable the
time out mechanism. If the time out mechanism is disabled then
faulty hardware can lock up the system.

ASPI Partition & Format Utility

INIFDISK.EXE is a DOS ASPI partition and format utility. It requires the
ASPIA100.SYS and INIDISK.SYS drivers to be loaded in order for it to func­tion properly . INIFDISK.EXE is installed by the ASUS DOSSETUP or SETUP
programs. Upon invocation, the initial screen will have two windows. The top
window will list all of the SCSI devices installed in the system. The user can
highlight a particular device by using the up and down arrow keys. The bot­tom window will display information about the device that is currently high­lighted in the top window. Inifdisk.exe can partition and format any SCSI
storage device that is not being controlled by the BIOS, this includes SCSI
disks, magnetic optical drives, and removable media devices. INIFDISK will
display two screens in which the bottom portion will explain all commands
possible in the top window.

Overview

PCI-SIU2 will support Microsoft W indows 95 and Windows 95B (OSR2) with
the addition of a software driver. The installation procedure described here
requires some experience in Windows 95 system setup and administration.
The device driver is transferred from the PCI-SIU2 Driver Disk 1 to the hard
drive where it is automatically initialized during the system boot routine.

The following files are used for installation and will be found on the PCI-
SIU2 Driver Disk 1 in the A:\win95 directory:

\WIN95\INIA100.MPD
PCI-SIU2 SCSI Host Adapter Windows 95 miniport driver.

\WIN95\INIA100.INF
Windows 95 installation information file.

Installation

The PCI-SIU2 driver developed for Windows 95 is loaded during the system
boot routine and will remain resident on the drive. This is accomplished by
following one of the three installation procedures listed:

• New Windows 95 and Windows 95B (OSR2) installation.

• Adding the ASUS Windows 95 device driver to an existing Windows
95 or Windows 95B (OSR2) system.

• Updating INIA100.MPD device driver

The procedures described to make changes to the system have distinct differ ­ences. It is strongly suggested that the selected procedure be read and under­stood before proceeding with the system configuration changes. Please read
the instructions carefully .

To determine which version of Windows 95 you have installed on your sys­tem, check the date of the KRNL32.DLL file located in your Windows direc­tory. A file date of 07/11/95 belongs to Windows 95, first release; 12/31/95
belongs to Windows 95a or 95 with Service Pack 1; 08/24/96 reflects Win­dows 95b or OSR2.

Using Multiple Host Adapters

UnixWare is capable of supporting up to eight SCSI busses. If you choose to
use multiple host adapters in your system, verify that each host adapter shared
interrupt level is set to IRQ10. Please refer to your system documentation to
set the interrupt levels.

Space for each host adapter in the system is configured and allocated by a
separate line in the file /ETC/CONF/SDEVICE.D/a100.

1 V erify that Y is selected in the second field at the line starting at a100

in the file /ETC/CONF/SDEVICE.D/a100 for each PCI-SIU2 in the
system.

UnixW are will automatically rebuild the kernel when an additional PCI-SIU2
is detected.

Removing the ASUS driver from a UnixWare system

1 Once a UnixWare session is established and a command prompt is ready ,

type (recall that UnixWare is case sensitive):

74 ASUS PCI-SIU2 User’s Manual

Troubleshooting

In the following section you will find commonly asked questions and answers
to problems encountered during the installation of your host adapter .

Question:What is Ultra2?
Answer: Ultra2 is a subset of the SCSI-2 specifications. Using LVD tech-

nology, which has less susceptibility to noise and has reduced
power consumption (due to the LVD designed into the chip tech­nology), the adapter is able to support Ultra2 wide devices with a
SCSI burst transfer speed of up to 80MB/sec and a point-to-point
(one device) cable length of 25 meters, or 12 meters with two or
more devices.

Question:On boot-up, not all the peripherals are scanned and recognized.
Answer: Verify that each of the SCSI devices on the bus has its own dis-

tinct SCSI ID number and all peripherals are receiving power.
Refer to your peripheral manual for information regarding chang­ing SCSI ID’s.

Verify the SCSI Termination is set correctly. Make sure the last
peripheral on the SCSI bus has termination. See the peripheral
manual for proper termination information.

After the above steps are executed, if you are still not recogniz­ing all attached peripherals, configure the host adapter to operate
in an Asynchronous T ransfer mode by changing its setting under
the SCSI Devices Setup section of the SmartSCSI Setup Utility.
This feature is discussed thoroughly in the chapter entitled Host
Adapter Setup.

Question:Can the PCI-SIU2 support legacy devices?
Answer: This feature will be found on Initio’s dual channel Ultra2 SCSI

host adapter (INI-A200U2W). In addition to supporting both
legacy and Ultra2 devices, the INI-A200U2W will provide sup­port for up to 30 total devices.

Question:What is the connector configuration on the adapter?
Answer: There are two connectors on the adapter: an internal and external

68-pin connector.

ASUS PCI-SIU2 User’s Manual 75

Troubleshooting

Question:Can I use the same cables for Ultra2 devices as I use for Ultra

peripherals?

Answer: It is recommended that you use cables specifically designed for

Ultra2 devices. The PCI-SIU2 kit contains a terminated Ultra2
Wide cable with connectors for four Ultra2 peripherals.

Question:What are the computer requirements for the PCI-SIU2?
Answer: The adapter requires a PCI 2.1 compatible PCI bus connection

with Bus Mastering capabilities.

Question:Under SCO UnixWare, the system displays a panic message or

crashes during bootup:

Answer: Reboot the system and verify that the PCI-SIU2 is using IRQ10.

Please Refer to your system documentation to set the interrupt levels
and your peripheral documentation for help in setting SCSI ID’ s.

In order to boot from the old UnixW are kernel, reboot the system
and execute the following steps:

• Begin an interactive boot session by pressing the
<SPACEBAR> at the BOOTING UNIXWARE prompt.

• At the system [boot]# prompt, type KERNEL=unix.org <ENTER>

• Type go <ENTER>
Consult the SCO UnixW ar e Installation Handbook “Troubleshoot-

ing” section to help isolate the problem. If it becomes necessary
to remove the ASUS device driver, please consult the “Remov­ing the ASUS Driver from a SCO UnixWare System” section of
this document.

Question:I don’t have any LVD Ultra2 devices yet. Can I still install my

SCSI-2 devices on the PCI-SIU2 until I get some?

Answer: Yes. In fact, by connecting your standard UltraWide devices to

the card you obtain the equivalent of UltraWide performance at a
3 meter length limit and speeds to 40MB/sec.

Question:What cables are included with the kit?
Answer: The kit contains a 5 connector Ultra2 68-pin terminated cable.

76 ASUS PCI-SIU2 User’s Manual

Troubleshooting

Question:How do I set the burst transfer rate for SCSI devices?
Answer: The maximum synchronous transfer rate is set in the SmartSCSI

Utility Interface. By pressing <Ctrl><I> at system bootup, you
can go into the SmartSCSI Ulility, click on Device Setup and
follow the onscreen options to select the desired transfer rate.

Question:Is it necessary that the last SCSI device on the cable is termi-

nated?

Answer: Yes. Improper termination on the host adapter or SCSI bus seg-

ment may cause the card not to initialize and the driver may fail
to load.

Question:On boot-up the message “SCSI BIOS Installed” is displayed, but

my system hangs.

Answer: Verify that the CMOS interrupt structure is set to INTA and the

CMOS IRQ level matches the jumper settings on the mother­board. Refer to your PC user manual.

Question:On boot-up I get a message “Missing Operating System”, dis-

played. The boot drive is greater than 1 gigabyte.

Answer: Verify the “DOS SPACE> 1 GB” is enabled in the PCI-SIU2

SmartSCSI Setup Utility.

B: DOS Space > 1GB

The default disk head mapping for ASUS SCSI host adapter is 255 heads and
63 sectors. This translates to a maximum accessible capacity of 8 GBytes per
drive under MS-DOS.

WARNING: If you have already installed the operating system on

your hard drives, changing the head mapping will cor ­rupt your files and cause other unexpected pr oblems.
Before changing any “DOS Space > 1GB” option set­ting, please back up your disk drives. Then you should
run the FDISK utility to delete all the partitions on
your selected disk drive. At this point you can switch
the setting, reinstall the operating system, and restor e
your backed up files.

All device drivers for the PCI-SIU2 will support different head mappings based
on the setting of “DOS Space > 1GB” option.

ASUS PCI-SIU2 User’s Manual 77

Troubleshooting

MS-DOS, OS/2 & Windows NT

Under MS-DOS, OS/2 & Windows NT, we recommend you enable “DOS
Space > 1GB” option if your SCSI hard disk has more than 1 GByte capacity

SCO UNIX

SCO UNIX does not have a 1 GByte barrier. Therefore, the “DOS Space >
1GB” option is not required to be enabled; however, you must make sure the
root file system is located below 1024 cylinders in order to perform the kernel
boot routines. If the size of the root file system is greater than 1 GByte or the
location of root file system is beyond 1 GByte, you should enable the “DOS
Space > 1GB” option.

SCO UNIX can not support different head mappings for each disk drive under
the same host adapter. The head mapping will be based on the setting repre­sented by target ID 0.

Drives with Multiple Operating Systems

It is mandatory that the same head mapping be used across multiple operating
systems on one drive. However you can use different head mappings on differ ­ent drives with the exception of SCO UNIX. It is recommended that you en­able “DOS Space > 1GB” option if the capacity of your SCSI hard disk has
more than 1 GByte.
