1-2 Introducing Your AP-10 SCSI PCI

Your AP-10 SCSI PCI is a high performance PCI-bus Bus
Mastering SCSI adapter which can connect up to seven SCSI
devices. It is an all-purpose SCSI adapter for users who want
to take advantage of the benefits offered by SCSI technology
such as multitasking, multiple device support, ease in using
portable devices, better data integrity through parity checking
and fast data transfer rate. Plus, it supports the most efficient
Bus Mastering DMA data transfer method so you can get the
maximum performance from iomega®/SyQuest® removable
cartridge drives, scanners, tape drives, CD-ROMs, CD-R/RW
drives, MO drives and many more.

The AP-10 SCSI PCI supports 32-bit data transfer across the
PCI bus at speeds up to 133MB/sec and synchronous burst
data transfer rates up to 10MB/sec on the SCSI bus.

You may be surprised to learn that hard disk drives are the
only devices that can really take advantage of higher data
transfer rates supported by the faster Ultra SCSI adapters

Serial No.

AP-10 SCSI PCI User's Manual

(20MB/sec for Ultra SCSI and 40MB/sec for Ultra Wide SCSI
drives). To get the optimum performance from other SCSI
devices such as fast SCSI hard disk drives, removable cartridge
drives, scanners and tape drives, 10MB/sec synchronous data
transfer rate is all you need. So, unless your requirements are
for high end data-intensive applications, such as used by
graphics and multi-media professionals (which could benefit
from the faster Ultra SCSI hard disk drives), this “all-purpose”
adapter is the ideal, affordable choice for adding SCSI devices
to your system.

The AP-10 SCSI PCI can function as a primary controller (the
on-board SCSI BIOS supports the INT 13h extension which
allows boot up in SCSI only systems); it can also be set as a
secondary controller in a system which already has a primary
IDE, ESDI or MFM hard drive controller card; or it can be set to
boot from a CD-ROM.

Regarding termination, your AP-10 SCSI PCI board is designed
with an active termination feature, which automatically sets the
proper termination of the board for you. Compared to passive
termination, this built-in auto-termination provides the most
accurate termination by adjusting to the actual voltage signal
levels on the bus.

The AP-10 SCSI PCI also comes with a full complement of
software support. Plus, a convenient on-board (ROM resident)
SCSI BIOS Setup Utility allows for easy configuration and
optimization of the board and peripheral devices.

Quick Installation

Chapter 2
Quick Installation

This chapter is a quick reference guide for installing your AP­10 SCSI PCI board for proper operation in your system.

This information assumes you are familiar with SCSI device
termination and installing boards in a computer. If you are a
new user, or find you need more detailed information, please
refer to Chapter 3: Introduction to SCSI for an overview of the
SCSI bus, cabling and rules for termination, and Chapter 4:
Hardware Installation, to install the SCSI board in your system.

The installation of the AP-10 SCSI PCI board is fully plug- and­play compatible. The configuration of the board is controlled by
the system BIOS automatically, there are no jumpers to set.

2-1 Installing Your AP-10 SCSI PCI

Perform the following instructions to install your AP-10 SCSI
PCI board:

Like all electronic equipment, your SCSI board is static
sensitive. Before opening the anti-static poly bag in which it
is packaged, discharge static electricity by touching the
computer chassis. Keep the board in its conductive wrapping
until it is ready to be installed in your system.

2-2

AP-10 SCSI PCI User's Manual

1. Make a backup copy of the Driver Installation Diskettes that
are included with your SCSI board.

Replacing or Adding

to Existing SCSI Boards

If the AP-10 SCSI PCI is to replace an existing
SCSI host adapter, remove that board first, as
well as any software device drivers for that
board.

If you are simply adding the AP-10 SCSI PCI
to a system with existing SCSI or IDE
controllers, there is no need to change existing
boards or software.

2. Make sure all power is OFF and disconnect power cord and
external cables from back of computer.

3. Remove the computer cover.

4. Remove the board from its anti-static wrap.

5. Select an available PCI-bus expansion slot and remove the
slot’s cover.

6. Install the AP-10 SCSI PCI in the expansion slot.

7. Secure the board with the slot cover’s retaining screw.

8. Connect all SCSI devices you want to use.

Do not use differential devices; use only
single-ended devices.

SCSI ID: Ensure each SCSI device has a unique SCSI ID.

2-3

Quick Installation

Termination: The AP-10 SCSI PCI will automatically set
its own termination correctly. However, you must ensure
that all other SCSI devices are properly terminated. Only
the last device on the internal and/or external SCSI Bus
should be terminated. All other SCSI devices should NOT
be terminated. (Refer to Chapter 3.)

Always use “Active Terminators” on devices that have this
feature. Refer to device documentation if necessary.

Internal Devices:

Use the 50-pin SCSI internal ribbon cable that was included
with the board to connect 8-bit SCSI devices.

(If you plan to connect more than two devices, see your local dealer
for a ribbon cable that supports all your devices.)

Make sure pin 1 on both connectors are matched when
making the connections. (The side of the cable with the
colored stripe running down its length indicates the pin 1
side of the connector.)

External Devices:

Installation of external SCSI cables can be made after the
cover is replaced. Cabling is limited in length to a total of

9.8 feet. The external cable can be daisy chained to include
up to 7 devices (in combination with internal devices.)
Leave the power OFF. Make sure all signal and power
cables are properly connected.

9. (Optional) Connect the drive activity LED cable (if present)
from your computer’s front panel to the J3 pin connector on
the AP-10 SCSI PCI board.

10. Replace the computer cover.

11. Reconnect all cables and power cord.

2-1.1 Option for Multiple Initiators

Jumper JP1 is provided to support certain conditions where the
SCSI bus is configured to have more than one SCSI host adapter
installed in at least two different computer systems sharing
peripheral devices. For multiple initiators on a single SCSI bus,
jumper JP1 can be used to set the termination ON all the time.
This will ensure proper termination in case one computer is off.

The AP-10 SCSI PCI is shipped without the jumper installed
and need not be changed in most cases.

Introduction to SCSI

Chapter 3
Introduction to SCSI

3-1 Introducing the SCSI

SCSI, which is the acronym for Small Computer System Interface,
is a specification for a peripheral bus and command set. The
SCSI specification defines a high performance interface that
distributes data among peripherals independently of the host,
thereby freeing the host computer for more user-oriented
activities.

SCSI offers the advantage of letting you connect up to seven (15
on wide SCSI) internal and/or external SCSI devices to one
host adapter card. This enables you to use the other available
expansion slots for other add-on cards such as internal modem
or network cards.

Another SCSI advantage over other peripheral interfaces is that
SCSI is designed to keep computers in step with advancing
technologies. SCSI enables host computers to connect with
virtually any SCSI peripheral device without always having to
overhaul system hardware and/or software. The host computer
does not have to “learn” a new way to communicate every time
a peripheral device is added – the conflicting issues of interrupts
and COM/LPT port assignments are eliminated by the
independent scheme of assigning a unique SCSI ID number to
each device on the SCSI bus.

However, one important requirement (defined by the SCSI
specification) is the rule of device termination:

When adding SCSI devices, you must ensure that
the devices on both ends of the SCSI bus are
terminated and that all devices in-between are
NOT terminated.

3-2

AP-10 SCSI PCI User's Manual

3-1.1 Basic SCSI Specifications

• A maximum of seven SCSI devices can be attached (daisy-

chained) to an 8-bit (referred to as narrow) SCSI bus. Up to
15 devices can be attached to a 16-bit (referred to as wide)
SCSI bus.

• Each SCSI device on the SCSI bus must have a different ID

assigned to it.

• The SCSI signals must be terminated at both ends of the

SCSI bus.

• When two SCSI devices communicate on the SCSI bus, one

acts as an initiator and the other acts as a target.

• Ultra SCSI specifications limit the total length of both

internal and external cables to up 3 meters (9.84 feet).

• It is strongly recommended that the same length of cabling

be used between external SCSI devices.

• Driver software must be installed to provide communication

between the SCSI bus and your computer.

The following table provides an overview of SCSI specifications:

Synch
Bus Conn- Transfer Max. # Cable

Introduction to SCSI

3-2 SCSI ID

Your AP-10 SCSI PCI controller can support up to seven SCSI
peripherals in a daisy chain configuration. When connecting
multiple SCSI peripherals, each device must be assigned a
unique SCSI ID number on the SCSI bus. ID settings range from
“0” for the first device to “7” for the seventh SCSI device. The
AP-10 SCSI PCI controller itself is factory set as ID 7 on the
chain. This ID positions the controller in an ideal position for a
single controller environment on the SCSI bus. (Note: it can be
changed to any ID position on the bus.)

Your AP-10 SCSI PCI controller can be placed in any physical
position on the bus. The priority is determined by the device ID
and not the device's physical location on the bus.

Check each SCSI device you are planning to connect for its
factory set ID number. The device ID is typically set via jumpers
or switches on most SCSI peripherals.

The following defines the basic rules for SCSI ID numbers:

• The range for assigning SCSI devices is 0 to 7, with 7 having

the highest priority, 0 the lowest.

• Device priority on the SCSI bus is only used when multiple
devices are trying to access the bus simultaneously.

• SCSI ID 7 is normally reserved for the SCSI controller. Other
devices use SCSI ID numbers from 0 to 6 (when the controller
is at default ID 7).

• If you have two or more SCSI hard drives installed, the drive
with the lower ID will be your boot drive. SCSI ID 0 is best
reserved for the boot hard disk drive; SCSI ID 1 is best
reserved as the second hard disk drive.

3-4

AP-10 SCSI PCI User's Manual

3-3 SCSI Termination

The SCSI bus must be properly terminated in order for its
connected devices to function correctly.

Only the devices installed on each end on the daisy­chained SCSI bus should be terminated; all other SCSI
devices should not be terminated.

Termination on internal mounted devices are generally
configured by “resistor terminators” or jumpers. Termination
on an external device usually requires simply plugging a
“terminator” into the open connector which would otherwise
receive the cable from the next device in the daisy chain. In some
cases, a switch may be used. Please refer to the manufacturer’s
documentation for any device you plan to add to your system
for its method of termination.

Internal Connections: one internal 50-pin connector is
provided for connecting narrow (8-bit) SCSI devices. The last
device on this bus should be terminated.

External Connections: one external high density 50-pin
connector is provided for connecting narrow (8-bit) SCSI
devices. The last device on this bus should be terminated.

AP-10 SCSI PCI Board: its Active Termination feature
automatically sets the proper termination of the board for you.
This guarantees proper termination of the board itself and
eliminates the need to remove the computer's cover if a change
is made in the SCSI bus configuration.

Figure 3-1 illustrates the correct terminations for the three
possible combinations of SCSI devices on the SCSI bus.

3-4 SCSI Cables

When connecting peripheral SCSI devices to your system,

it is important that you always use high quality cables.

For external devices use: double shielded twisted pair cable.
For internal devices use: unshielded flat ribbon cable.

DO NOT BUY CHEAP CABLES.

• External device cables should be constructed of high quality
double-shielded twisted pair cable.

Mid-quality external cables may be okay for slower SCSI-1
or SCSI-2 devices. However, Fast SCSI-2 and particularly
Ultra SCSI devices are extremely sensitive to cable quality
and will not perform reliably if high quality cabling is not
used.

• Use the shortest cable possible. Do not use cables shorter
than 30 cm (11.8 inches) between any two external SCSI
devices.

Cable length also impacts performance because signals
weaken with longer distance of travel and are susceptible to
noise.

• Use the same length of cable between each external
SCSI device.

• The Ultra SCSI specification limits the total length of
all cables to up to 3 meters (9.84 feet) or 4.9 feet if more than
four devices are connected.

AP-10 SCSI PCI User's Manual

Proceed with the following instructions to install the AP-10
SCSI PCI in your computer. General instructions for installing

the board are given since the design of computer cases varies.
Refer to your computer’s reference manual whenever in doubt.

1. Make a backup copy of the Driver Installation Diskettes that
are included with the board.

2. Turn OFF the power to your computer and any other
connected peripheral devices.

3. Unplug all power cords and cables from the back of the
computer. (Be sure to note the cable connections for
reconnection when the installation is complete.)

4. Remove your computer’s cover by removing its mounting
screws with a screwdriver. Slide the cover OFF.

5. Remove the board from its anti-static wrap.

6. Option for Multiple Initiators only: Jumper JP1 is
provided to support certain conditions where the SCSI
bus is configured to have more than one SCSI host
adapter installed in at least two different computer
systems sharing peripheral devices. For multiple
initiators on a single SCSI bus, jumper JP1 can be used to
set the termination ON all the time. This will ensure
proper termination in case one computer is off. The AP-

10 SCSI PCI is shipped without the jumper installed
and need not be changed in most cases.

4-2 Connecting the SCSI Devices

You can connect up to seven internal and/or external SCSI
devices to your system via the external and internal ports on
your AP-10 SCSI PCI board.

NOTES

• Do not connect differential devices; use only
single-ended devices.

• It is important that you always use high-quality
double shielded twisted-pair external cable.

In order to run 10 MBytes/sec data transfer rate,
SCSI specifications limit the total combined
length of all cables to up to 3 meters (9.84 feet)
(4.9 feet for more than four devices).

4-2.1 Internal SCSI Devices Only

1. Your AP-10 SCSI PCI provides one internal 50-pin connector.

2. Configure and install each internal SCSI device, such as
hard disk or CD-ROM drives in your computer according
to the manufacturer’s instructions.

a. Follow the rules for terminating devices on the SCSI bus

(see Chapter 3). Remember: only the devices at each end
of the SCSI bus must be terminated. Refer to the
manufacturer’s documentation for proper termination
of the devices you plan to install.

b. Verify that the factory default SCSI ID number set on

each device you plan to install is valid. If there is a
conflict, reset it to an available ID (0-6 assuming board
default of ID 7) following the manufacturer’s
instructions.

3. Use the internal 50-pin 3-position SCSI ribbon cable that
was included with the board for attaching 8-bit SCSI
devices. (If you plan to connect more than two devices, see your

local dealer for a ribbon cable that supports multiple devices.)

a. Plug the last connector on the ribbon cable into

the connector on the internal SCSI device
following the appropriate device manufacturer's
instructions. Make sure “pin 1” on the cable’s
connector, indicated by the colored edge-stripe)
is matched with the device connector’s pin 1.
Make sure the connector is well seated.

b. To connect a second internal SCSI device, plug the

middle connector on the ribbon cable into the
connector on the second internal SCSI device.
Again be aware of matching pin 1s. Make sure the
connector is well seated.

c. Plug the connector at the other end of the ribbon

LED, to the J3 connector on your AP-10 SCSI PCI. The LED
will light when there is SCSI bus activity. (Refer to your
computer’s manual regarding this LED cable.)

For systems with a two-position LED cable, plug its 2-pin
connector to pins 1 and 2 of connector J3.

Note: If you make this connection, the LED will no longer

indicate non-SCSI activity, such as for an IDE drive if
installed.

5. After completing all your internal connections, double
check that the devices are installed properly (including
terminations), and the cable connections are secure.

6. Replace the cover and reconnect all power cords and cables
to the back of the computer.

If you plan to attach external peripheral device(s) at this time,
make sure the termination on all devices is correct. (Refer to
Chapter 3, page 3-4.) Then, continue with the next section to make
your external connection(s) to the AP-10 SCSI PCI's J2 port.

4-9

Hardware Installation

4-2.2 External SCSI Devices Only

NOTE

Your AP-10 SCSI PCI is shipped with one internal
ribbon cable You will need an additional double­shielded twisted-pair cable for each external
peripheral device you wish to connect — which
should be daisy-chained off the external J2
connector on the board.

1. Configure each SCSI device, such as a scanner or
CD-ROM drive according to the manufacturer’s
instructions.

a. Follow the rules for terminating SCSI devices. (See

Chapter 3, page 3-4.)

b. Verify that the default SCSI ID number set on each

device is valid. If there is a conflict, reset it to an available
ID (0-6 assuming board default of ID 7) following the
manufacturer’s instructions.

2. Attach the high density 50-pin SCSI cable connector end to
the external connector on the AP-10 SCSI PCI and the other
end to your SCSI device.

If you are connecting more than one device, connect the
cables between the SCSI devices in a daisy-chained
configuration.

3. Connect the power cords to the peripherals and refer to
their manuals for operation.

4-3 Host Computer Configuration

Most computer manufactures with a PCI bus automatically
configures the add-on card's I/O port address, IRQ Channel
and BIOS address. If this is not the case with your computer
system, you will need to enter the system Setup program and
manually change the PCI setting.

There are two methods of configuring the PCI bus from the host
computing system:

1. Setting jumpers on the host system motherboard.

2. Setting CMOS incorporated into the host system.

In either case, you will need to refer to the host computer system
documentation to complete PCI bus activation and setup.

Depending on your system configuration, refer to the following
to configure the system’s CMOS setup:

1. If an IDE drive and a SCSI drive are both present in the

system: the IDE drive will be your boot drive (Drive C)
and its drive type must be defined in CMOS Setup; the
drive type of the SCSI drive (Drive D) must be set to
“Not Installed”.

2. In a SCSI only system, CMOS setup must be run and both

"Drive C" and "Drive D" must be defined as “Not
Installed”.

After updating the CMOS Setup, save the changes to rewrite
the CMOS configuration. Then, reboot your system.

4-12

AP-10 SCSI PCI User's Manual

4-4 Where to Next?

At this point, your AP-10 SCSI PCI and its attached SCSI hard
disk drives are ready for use. Proceed with the following:

• Run the SCSI BIOS setup utility by pressing <Ctrl><I>

keys when prompted during system bootup. Refer to
Chapter 5: SCSI BIOS Setup for instructions on how to use
this convenient program to configure the SCSI bus.

• Install the appropriate drivers for your operating system
and peripheral devices. Refer to Chapter 6: Software
Installation for instructions on how to install the software
drivers.

Note that Windows 95 supports most SCSI devices. (Certain
device drivers may also be independently supplied by the
device’s manufacturer.)

If your PC already has an operating system (OS) installed: go
to Chapter 6, Software Installation and follow the applicable
instructions to install the appropriate software files for your
operating system.

If an operating system is not yet installed: proceed first with
its installation. The SCSI BIOS has built-in hard disk drive
support, so you should experience normal operation with any
attached SCSI hard drive. Then, install the appropriate software
files for your OS. Refer to Chapter 6, Software Installation for
instructions.

To maximize the use of multi-tasking operating systems, such
as Novell, UNIX, Windows NT or OS/2, some of the default
settings of the SCSI BIOS configuration may be changed. Your
AP-10 SCSI PCI includes its own SCSI BIOS Setup utility for
configuring the SCSI Bus. Refer to Chapter 5, SCSI BIOS Setup
for instructions on how to use this menu-driven setup program
to manually configure its feature options.

5-1

SCSI BIOS Setup

Chapter 5
SCSI BIOS Setup

This chapter will guide you through the use of the on-board
SCSI BIOS Setup Utility. This utility simplifies the SCSI
installation process by eliminating the need for opening the
system to change system jumpers and switch settings. All
necessary AP-10 SCSI PCI functions for customizing your
system are accessible through this utility.

5-1 Power up Introduction

After verifying your hardware installation and running the
System CMOS Setup (as described in Chapter 4, page (4-11),
your newly installed AP-10 SCSI PCI controlled SCSI bus is
now ready for setup. First turn your external SCSI peripherals
ON (if present); then, power ON your computer system. The
system monitor should display the following information, but
may vary, based on the system BIOS manufacturer:

• The normal POST and memory test procedure.

• The AP-10 SCSI PCI’s sign on message including a list of
detected 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 controller’s BIOS Setup Utility to initialize
a SCSI disk drive and lay the foundation for a bootable SCSI
drive.

negotiate for asynchronous transfers. A device is always
checked first for synchronous transfer; then asynchronous. If
you know a device is only asynchronous, then selecting “yes”
will save time by not checking for synchronous transfers.

Yes: Select this if you know the device does not support

synchronous transfers—only asynchronous transfers.

No: Select this if you know the device supports synchronous

transfers. (Default setting.)

Max. Synchronous Transfer: Your AP-10 SCSI PCI supports data

transfer speeds to and from the SCSI bus up to 10 MBytes/sec.
Each device can be set for its specific synchronous data transfer
rate. You can choose from a range between 5 and 20 MB/sec.
This feature will save the time that would otherwise be needed
to negotiate the speed before initiating transfers. The following
identifies standard settings.

hard disk capacity greater than 1 gigabyte— up to 8 gigabytes.

Yes: Select this for SCSI hard disks greater than 1 gigabyte. It

extends the upper limit from 1 GByte to 8 GBytes by
increasing the translation scheme to 255 heads and 63
sectors per track. This is a powerful option. DATA CAN
BE LOST BY CHANGING SETTINGS. (Default setting.)

No: Select this for SCSI hard disks less than or equal to 1

gigabyte where DOS limits the number of cylinders per
drive to 1024. The host adapter uses a translation scheme
of 64 heads and 32 sectors per track.

Spin Up Disk Drive: Some drives have a built-in power saving

mode. When this type of drive is not being accessed, it will slow
down or turn off.

Yes: Select to support drives with power-saving feature.

No: Select if device is not a power-saving feature drive.

(Default setting.)

Enable Disconnect: The host adapter uses this option to allow a

device to temporarily disconnect/reconnect from the SCSI
bus. 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 = Yes.)

CAUTION

It is highly recommended that the default
setting for this option be used, unless your
drive is incapable of supporting disconnects.

AP-10 SCSI PCI User's Manual

BIOS Support For More Than 2 Drives :

With MS-DOS 5.0 or later,
enables the SCSI BIOS to control more than two hard disk
drives without having to install special drivers. It allows the
DOS fdisk program to partition up to eight disk drives,
eliminating the need for aspidisk. If it is not needed, disable this
feature to save memory resources.

Yes: If you have two or more hard disk drives and have DOS

5.0 or later. (Default setting.)

No: If you have an earlier version than DOS 5.0 or do not

have more that two hard disk drives.

The optimum ID for multiple drive operation is device ID0 for
a system disk and device ID1 for the second drive.
(Default setting.)

BIOS Treat Removable Disks as Fixed Disk: Allows the BIOS to

control removable-media drives, such as iomega, Bernoulli
and SyQuest drives, as if they were hard disk drives, without
installing additional software drivers. To have the ability to
interchange media during operation, additional third party
drivers will be needed for that peripheral device.

This feature can be used for system security. Removable disks
configured as boot disks can be used to lock your system when
they are removed. To do this, make sure no other boot drive is
in your system. Then, format a removable cartridge and partition
it to be a boot device. Insert this cartridge before powering up,
and remove it after powering down.

Yes: The BIOS supports all removable-media drives like a

hard disk, including as a boot drive.

No: Removable-media drives are not treated as hard disks.

In this mode, software drivers are needed because the
drives are not controlled by the BIOS. (Default setting.)

NOTE

DO NOT remove media controlled by the SCSI BIOS
while the system is powered on. Data will be lost! The
BIOS does not support removability while the system
is turned on. If you want to remove media while the
system is powered, you must install additional third
party device drivers.

do not need reformatting. However, in cases where a drive has

been used with other host adapters, the drive should have a
low-level format performed. This sets the media to a state
which is easily recognized by the host adapter on the SCSI bus.

WARNING: All data will be lost when performing
a low-level format. Make sure you back up all data
before proceeding with this operation. The format
process cannot be aborted once it is in progress.

Software Installation

Chapter 6
Software Installation

The following sections describe the procedures for installing drivers
to enable your AP-10 SCSI PCI to operate properly under specific
operating system environments.

6-1 MS-DOS/Windows 3.1 Driver Installation

Your AP-10 SCSI PCI’s on-board BIOS provides the necessary
functions to support most operations. When using MS-DOS
v5.0 or later, the BIOS will support up to seven hard disks;
for DOS 4.01 or below, only two drives are supported.

The BIOS supports most hard disk functions without
additional device drivers. However, you will need to install
a device driver provided by the device’s manufacturer to
support other types of SCSI devices, such as CD-ROM, tape
backup, scanner, etc.

IMPORTANT

It is important that the SCSI bus hardware and
operating system are installed correctly before
proceeding further.

6-1.1 For an Existing MS-DOS System

Perform the following steps to install the ASPI driver for the
MS-DOS operating system:

1. Turn on your computer to boot to the DOS prompt.

2. Insert the AP-10 SCSI PCI Driver Installation Disk 1 into the
floppy drive.

3. At the a:> or b:> prompt, type: dossetup and press <Enter>.

4. Follow the on screen instructions.

5. Select “Reboot Now” to reboot the system to load the ASPI
driver. Remove the diskette to complete bootup.

If a CD-ROM, tape drive, scanner, or optical drive is installed
on your system, a device driver may be needed. A driver
may be provided by the manufacturer to provide proper
support for that particular device. Please refer to your
peripheral device manufacturer documentation for more
information.

6-1.2 For an Existing Windows 3.1x System

Perform the following steps to install the ASPI driver for

Windows 3.1x operating system. It is important the SCSI
adapter and Windows 3.1x operating system are installed
correctly before proceeding.

NOTE

If you already installed the ASPI driver for
MS-DOS, you do not need to reinstall the driver.

1. Turn on your computer to boot into DOS. Type win to run
Windows 3.1x.

2. Insert the AP-10 SCSI PCI Driver Installation Disk 1 into the

Troubleshooting

7-2 DOS Space > 1GB

The default disk head mapping for the AP-10 SCSI PCI is 64
heads and 32 sectors. Under this configuration, the MS-DOS
limit is 1024 cylinders per drive. This translates to a maximum
accessible capacity of 1 GB per drive. By changing the head
mapping to 255 heads and 63 sectors, the “DOS Space > 1GB”
option can support disk capacities up to 8 gigabytes under MS­DOS.

WARNING: If you have already installed the operating
system on your hard drives, changing the head mapping will
corrupt your files and cause other unexpected problems.
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 restore your backed up files.

All device drivers for the AP-40 SCSI PCI will support different
head mappings based on the setting of “DOS Space > 1GB”
option.

7-2.1 MS-DOS, OS/2 & Windows NT

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

7-2.2 NetWare 386

NetWare does not have a 1GB barrier. Therefore, the “DOS
Space > 1GB” option is not required to be enabled; however,
you must verify the boot partition is located below 1024 cylinders.
If the size of your boot partition is greater than 1 GB or the
location of the boot partition is beyond 1 GB, you should enable

7-2.3 SCO UNIX

SCO UNIX does not have a 1 GB 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 GB or the location of root
file system is beyond 1 GB, you should enable the “DOS Space
> 1GB” option.

SCO UNIX cannot 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.

7-2.4 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 different 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 GB.
