Overview

Thank you for purchasing Iwill BS100 motherboard.This operation manual will instruct you how to
configure and install the system properly. It contains an overview about the engineering design and
features of this product. Also, this manual provides useful information for later on upgrade or
configuration change. Keep this for your future need.

YEAR 2000 issue

The IBM compatible PC utilizes a Motorola MC146818 compatible Real Time Clock (RTC) chip to
maintain the date and time. Unfortunately, the “century” is not manipulated by the RTC. It uses 8­bit of information to report the year and can only hold the last two digits of a year in packed BCD
format. So 1997 is reported solely as 97. Since the RTC also contains non-volatile memory, IBM
specified a location in the memory to hold “century” information. By combining the century data
with the year data, software can obtain a full 4-digit year. When the Year 2000 occurs, the RTC
reports the year as ’00’ and the “century” in RTC memory will contain ’19.’ Combining the full 4­digit year yields 1900, not 2000. Any applications which compares dates, or uses relative dates to
perform functions will see an incorrect dates.

Motherboards contain BIOS, which is one of the key ingredients to check for systems designed to
handle the year 2000. All motherboards currently shipped from Iwill contain BIOS capable of
handling the year 2000 date correctly. The BIOS contains a feature that checks the least two
significant digits of the year stored in the RTC during each BIOS request (INT 1Ah) to read the
date and, if less than `80', updates the century byte to `20'. This feature enables operating systems
and applications using the BIOS date/time services to reliably manipulate the year as a four-digit
value.

Be aware that the BIOS capability alone does not ensure that the system will handle the transition
correctly. Other system components such as the operating system and application software also
need to be able to handle the year 2000 date and recognize the date format from other pieces.

2.3 Installation procedures

2.3.1 Processor (Slot 1 and FAN1)

The motherboard supports single Pentium® II processor. The processor’s VID pins automatically
program the voltage regulator on the motherboard to the required processor voltage. The
motherboard currently supports processors that run internally from 233 MHz to 500 MHz.

The Pentium® II processor is packaged in a Single Edged Contact (S.E.C.) cartridge. The cartridge
includes the processor core, second-level cache, thermal plate and back cover. The processor
connects to the motherboard through the Slot 1 connector, a 242-pin edge connector. When
mounted in a Slot 1 connector, the processor is secured by a retention mechanism attached to the
motherboard.

First, screw the main body of Slot 1 retention mechanism to the motherboard then insert the
processor cartridge along the retention mechanism in vertical direction. A “click” sound will be
heard while the processor is located right in position. Finally, attach the cooler’s power cable to the
processor fan header on the motherboard.

2.3.3 Main memory (DIMM0--3)

The motherboard has four dual inline memory module (DIMM) sockets, which supports memory
size from 8 MB to 1 GB with SDRAM and EDO DRAM. The Synchronous DRAM (SDRAM)
improves memory performance through memory access that is synchronous with the memory clock.
The Error Checking and Correcting (ECC) memory improves system security by detecting and
correcting error bit when accessing memory.

The motherboard supports the following memory features:

JEDEC MO-161 compliant 168-pin DIMMs with gold-plated contacts

3.3 V memory module only
ECC logic detects multiple-bit errors and corrects single-bit errors (SDRAM)
Unbuffered SDRAM, Registered DIMM or 60-ns 3.3 V EDO DIMMs
16 / 64 Mbit DRAM technology
Symmetrical and asymmetrical DRAM addressing
Single-sided or double-sided DIMMs

3.3 V EDO and SDRAM DIMMs can NOT be installed on the same motherboard

Memory can be installed in DIMM sockets without any order restriction. The memory type, size,
speed can vary between sockets. The BIOS automatically detects memory type, size and speed.

Note 1. In order to reduce the loading, the total memory chip count installed on the system
should not exceed 72 unless the Registered DIMMs are used.

18

Note 2. The Serial Presence Detect (SPD) information is highly recommended on all 100
MHz DIMMs for this motherboard. This function is implemented using an EEPROM
component on the memory module. The nonvolatile storage device contains data
programmed by the DIMM manufacturer that identifies the module type and various
SDRAM organization and timing parameters. A warning message will be prompted if any
DIMMs installed on this motherboard has no SPD EEPROM. In this case, the system might
fail to be stable without correct timing parameters.

2.3.4 Accelerated Graphics Port (AGP)

The Accelerated Graphics Port (A.G.P.) is a high-performance interconnect, especially for graphic­intensive 3D applications. A.G.P. is independent of the PCI bus and is intended for exclusive use
with graphical display devices. The A.G.P. supports AC timing for 133 MHz data transfer rates,
allowing data throughput of 533 MB/sec.

The most important feature of A.G.P. is DIME (Direct Memory Execute). DIME needs to allocate
some system memory via the O.S. to access large textures outside the local graphic memory of the
card. In order to take advantage of DIME feature, some software components should be installed or
upgraded in the system.

For Windows NT 4.0: Upgrade to "Windows NT 4.0 Service Pack 3".
For Windows 95: Upgrade to Windows 95 OSR 2.1.

Install DirectX 5 from Microsoft.

2.3.5 Primary/Secondary IDE connectors (IDE0 and IDE1)

The motherboard has two bus-mastering IDE interfaces, which support PIO Mode 3 / 4 and Ultra
DMA 33 mode transfer. These interfaces support IDE disks, ATAPI devices (ex: CD-ROM), ZIP
and LS-120 devices. If two devices are connected to one channel, one should be set to "Master" and
the other one to "Slave" (Refer to device operation guide).

Simply connect the 40-pin IDE cable between the IDE/ATAPI devices and these connectors on the
motherboard. For a performance reason, we suggest that connect the disk drive to the primary
channel and other devices like CD-ROM to the secondary channel.

2.3.6 Floppy drive connector (FDC)

The motherboard has one floppy interface, which supports 360K, 720K, 1.2M, 1.44M, 2.88M, 3
Mode floppy drives and QIC-80 Floppy tape drive. It supports up to two devices in any capacity
with the same connector. Simply connect 34-pin floppy cable between this connector and floppy
drives.

2.3.7 Serial port connector (S1 and S2)

The two 9-pin D-Sub serial port connectors on the back panel are compatible with 16550 UART.
These ports are used for serial mouse, serial printer, fax modem…etc. Simply connect the serial
devices to these connectors.

19

2.3.8 Parallel port connector (LPT)

The connector for the multi-mode parallel port is a 25-pin D-Sub connector located on the back
panel. It is used for the printer or other parallel devices. Simply connect the parallel cable between
devices and the parallel port connector.

2.3.9 Universal Serial Bus (USB)

The USB is suitable for mid-to-low speed devices like mouse, keyboard, joystick...etc. In the past,
all these devices were using different connectors, and it is difficult for end users to install the
system. With USB technology, users only need to plug all their USB peripherals on the connector
in chain and ready to go.

The motherboard supports following USB features:

Self-identifying, hot pluggable peripherals
Support of isochronous and asynchronous transfer type
Supports for a maximum of 127 physical devices
Supports data transfer rate up to 12 Mbit/sec

The motherboard has two USB ports; any USB peripheral can be connected to either port. For more
than two USB devices, an external hub can be connected to either port.

2.3.10 PS/2 keyboard and mouse connectors (KB/MS)

The keyboard connector is a 6-pin mini-DIN connector located on the back panel (the bottom one).
Simply connect the standard PS/2 keyboard into this connector. The PS/2 mouse connector is a 6­pin mini-DIN connector on the back panel. Simply connect the PS/2 mouse into this connector.

Note that power to the computer should be turned off before a keyboard and/or mouse is
connected or disconnected.

With a proprietary application, the system hardware monitor logic will check the voltage,
temperature and fan speed all the time. If any failure occurs, the application will prompt warning
message in a real time.

2.3.21 SCSI Subsystem (CH-A, CH-B and JP2)

The onboard SCSI subsystem features the Adaptec AIC-7895, which contains a dual-channel Ultra
Wide SCSI controller and a PCI bus master interface. It provides up to 40 MB/sec throughput per
channel. The motherboard has three SCSI connectors. Channel A has a high-density 68-pin Wide
connector as well as a 50-pin Narrow connector, while channel B has a high-density 68-pin Wide
connector only.

Use the onboard 68-pin connector for cabling to 16-bit Wide SCSI devices and use the 50-pin
connector for cabling to 8-bit narrow devices. From end to end, a SCSI cable is route, in a daisy
chain fashion, from the last internal SCSI device to each subsequent internal device including the
onboard host controller. The cable can then connect to an optional converter card (External Kit)
installed in an unused I/O slot of the chassis. From the external kit, an external SCSI cable can be
used to connect external SCSI devices.

For proper operation of Ultra / Ultra Wide SCSI devices, the overall length of the SCSI cable from
the last internal device to the last external device should not exceed 3 meters with four Ultra / Ultra
Wide SCSI devices and 1.5 meters with eight peripherals per channel.

Install or enable terminators on the last physical SCSI device at each end of the SCSI bus (Note that
a SCSI bus can comprise several SCSI cables) and remove or disable terminators on all other
devices on the SCSI bus. The motherboard will set its terminator to proper state automatically.

Make sure you have assigned each device on the SCSI bus, including the onboard SCSI controller,
a unique SCSI ID.

Note: JP2 is a jumper block for enabling/disabling onboard SCSI controller. The default
setting, 1-2, enables the onboard SCSI controller. If you want to disable the onboard SCSI

controller, put the jumper cap to pins 2-3.

24

The following figure shows the correct SCSI bus topology.

2.3.22 Adaptec RAIDport connector (RAIDPORT II)

The onboard RAIDport II connector, in conjunction with an Adaptec ARO-1130CA-B RAIDport II
card and the onboard SCSI controller, provides a complete client solution. The RAIDport card
supports the following features for enhancing performance, data redundancy and data availability:

RAID coprocessor
Support for RAID levels 0 (striping), 1 (mirroring) and 0/1
Hot-swap drive support
Hot-spare standby
Dynamic sector repairing

System BIOS Setup

3.1 Introduction

The motherboard uses an AWARD BIOS, which is stored in flash memory and can be upgraded
with a disk-based program. The setup program is for viewing and changing the BIOS setting for a
computer. These settings are stored in battery-backed RAM so that it retains all the settings when
the power is turned off.

3.1.1 Upgrade BIOS

The BIOS can be upgraded from a diskette with the Award Flash utility -- AWDFLASH.EXE. The
BIOS image file and the update utility are available from Iwill’s WEB site: www.iwill.com.tw.

3.1.2 Recovering BIOS Data

Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage
occurs while the BIOS being updated in flash memory. The BIOS can be recovered from a diskette.
To create a BIOS recovery diskette, a bootable diskette must be created and the recovery files
copied to it. The recovery files are available from Iwill.

Note: No video is displayed during the recovery process.

3.1.3 Enter BIOS setup program

The BIOS setup program is accessed by pressing the <Del> key after Power-On Self Test (POST)
memory test begins and before the scanning of IDE devices. During that time, a message “Press
DEL to enter SETUP” will be displayed at the bottom of the screen. If the message disappears
before you respond, you can restart the system by

Turning off the system power then turn it on again, or
Pressing the "RESET" button on the system case, or
Pressing <Ctrl>, <Alt> and <Del> keys simultaneously.

3.1.4 Using BIOS setup program

The following table shows the function keys available for menu screens.

<Up> Move to the previous field
<Down> Move to the next field
<Left> Move to the field in the left hand
<Right> Move to the field in the right hand

26

<Esc> Quit from setup program without saving changes, or

Exit from current menu page and return to main menu page
<PgUp> or <+> Select the previous value for a field
<PgDn> or <-> Select the next value for a field
<F1> Bring up a help screen for the current field
(Shift)<F2> Change screen color. F2 to select color forward, (Shift) F2 to select

color backward
F10 key Save the current value and exit setup program

NOTE

Generally, the BIOS default settings have been carefully chosen by the system manufacturer to
provide the absolute maximum performance and reliability. It is very dangerous to change any
setting without full understanding. We strongly recommend that

DO NOT update your BIOS if the system works perfect.
DO NOT change any setting unless you fully understand what it means.

If the system does not work smoothly after changing the BIOS setting, follow the procedures
described before to enter setup program then load the default to the original manufacturer default
setting.

If the system is no longer able to boot after changing the setting, the only way to recover it is to
clear the data stored in RTC CMOS. To reset the RTC CMOS data, you need to change the jumper
cap of JP1 from 1-2 close to 2-3 close, then set to default 1-2 close again. After that, you should get
into BIOS setup program and choose LOAD SETUP DEFAULTS to get original manufacturer
default setting in your CMOS.

3.2 Main Menu

The main menu allows you to select from several setup pages. Use the arrow keys to select among
these pages and press <Enter> key to enter the sub-menu. Note that a brief description of each
highlighted selection appears at the bottom of the screen.

SCSI BIOS Setup

4.1 Introduction

The motherboard has an configuration utility, SCSISelect, which allows you to change SCSI
controller settings. SCSISelect also includes SCSI utilities that let you list the SCSI IDs of devices,
format SCSI disk drives, and check them for defects.

4.1.1 Enter SCSISelect utility

To enter the SCSISelect utility, boot the computer and press <Ctrl><A> when the following
message appears:

Press <Ctrl><A> for SCSISelect ™ Utility !

4.1.2 Using SCSISelect utility

The following table shows the function keys available for menu screens.

<Esc> Go back to previous screen or exit SCSISelect utility
<Enter> Select an option
<Up> Move to the previous field
<Down> Move to the next field
<F5> Switch between color and monochrome
<F6> Reset to default

Before the main screen is displayed, you must first select SCSI channel to configure. After you
select the channel and press <Enter>, the main screen is displayed.

4.2 Configure/View Host Adapter Settings

When selected, this brings up the Configuration Menu.

4.2.1 Host Adapter SCSI ID

Each channel on the controller has the default SCSI ID of 7, which gives the channel the highest
priority on the SCSI bus. We recommend that you leave this ID at 7.

Options 0 / 1 / 2 / 3 / 4 / 5 / 6 / 7 (*) / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15

46

4.2.2 SCSI Parity Checking

SCSI parity checking is a procedure used by the channel to verify the accuracy of data transfer on
the SCSI bus. By default, parity checking is enabled on all channels. Disable parity checking for a
channel if any SCSI device on the channel does not support SCSI parity.

Options Enabled (*)

Disabled

4.2.3 Host Adapter SCSI Termination

This field configures the SCSI termination on the motherboard.

Options Description
Automatic Set terminator to proper state automatically. This option is

only available when all the SCSI connectors on the
motherboard connect to one end of cable. If you attach the
middle (not extreme ends) connector of the cable to either
narrow or wide connector on the motherboard, you should not
select this option.

Low ON/High ON Enable both High and Low terminators
Low OFF/High ON Disable the Low terminator and enable the High terminator
Low OFF/High OFF Disable both High and Low terminators

4.2.4 Boot Device Options

Press <Enter> to bring up Boot Device menu.

4.2.4.1 Boot Channel
This field specifies the SCSI channel from which to boot first. It is conjunction with Boot

SCSI ID and Boot LUN Number fields to specify the device from which to boot.

Options A First (*)

B First

4.2.4.2 Boot SCSI ID
This field specifies the SCSI ID of the device from which you wish to boot.

Options 0 (*) / 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15

This field specifies which LUN to boot from on the boot device if the boot device has

multiple LUNs and Multiple LUN Support field is enable.

Options 0 (*) / 1 / 2 / 3 / 4 / 5 / 6 / 7

47

4.2.5 SCSI Device Configuration

Press <Enter> to bring up SCSI Device Configuration menu.

4.2.5.1 Initiate Sync Negotiation
Synchronous negotiation is a SCSI feature that allows the SCSI channel and its attached

SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster than
asynchronous data transfer. The Initiate Sync Negotiation field determines whether the
channel initiates synchronous negotiation with the SCSI device.

Options yes (*)

no

4.2.5.2 Maximum Sync Transfer Rate
This field specifies the maximum synchronous data transfer rate that the channel supports.

Options 40.0 (*) / 32.0 / 26.8 / 20.0

4.2.5.3 Enable Disconnection
This field specifies whether the channel allows a SCSI device to disconnect from the SCSI

bus. Enabling disconnection allows the channel to perform other operations on the SCSI bus
while the SCSI device is temporarily disconnected.

Options yes (*)

no

4.2.5.4 Initiate Wide Negotiation
This field specifies whether the channel attempts 16-bit instead of 8-bit data transfer.

Options yes (*)

no

4.2.5.5 Send Start Unit Command
This field specifies whether the channel sends the Start Unit command to the SCSI device.

Enabling this option reduces the load on the computer’s power supply by allowing the
channel to turn on SCSI devices one-at-a-time when the computer boots. Otherwise, all
SCSI devices turn on at the same time.

Options yes

no (*)

48

4.2.5.6 BIOS Multiple LUN Support
When enabling, the SCSI BIOS support multiple LUN on a SCSI device. Otherwise, the

SCSI BIOS can recognize LUN 0 only.

Options yes

no (*)

4.2.5.7 Include in BIOS Scan
This field specifies whether the SCSI BIOS supports devices attached to the SCSI bus

without the need for device driver software. When selected yes, the SCSI BIOS controls the
SCSI device. This option can be useful when changing boot order.

Options yes (*)

no

4.2.6 Advanced Configuration Options

The Reset SCSI Bus at IC Initialization, Support Removable Disks Under BIOS as Fixed Disks, and
Extended BIOS Translation for DOS Drives > 1 GByte are set for each channel individually. The

other advanced settings apply to the SCSI controller globally. You specify the global settings on
Channel A, they will automatically apply to the other channels.

4.2.6.1 Plug and Play SCAM Support
SCAM is a method that participating SCSI devices on a bus, which is used to dynamically

assign SCSI IDs. Some legacy devices can not reside on a SCSI bus where SCAM protocols
execute. Select Disabled if such a device is attached to the SCSI bus.

Options Enabled

Disabled (*)

4.2.6.2 Reset SCSI Bus at IC Initialization
If the SCSI BIOS is enabled, it always resets the SCSI bus when you reboot the computer

and then scans for SCSI devices. This field specifies whether the BIOS waits 2 seconds
after resetting the bus before scanning the bus for SCSI devices. At the default setting,
enabled, the BIOS waits 2 seconds.

Options Enabled (*)

Disabled

4.2.6.3 Extended BIOS Translation for DOS Drives > 1 GByte
Most versions of MS-DOS are limited to 1024 cylinders per drive. The standard translation

scheme for SCSI host adapter, using 64 heads and 32 sectors, provides a maximum
accessible capacity of 1 Gbytes. To support disk drives larger than 1 Gbyte, the SCSI BIOS
includes an extended translation scheme. This scheme supports disk drives as large as 8
Gbytes under MS-DOS. With extended translation enabled, drives handled by the SCSI
BIOS use extended translation if their formatted capacity is greater than 1 Gbyte, and drives
smaller than 1 Gbyte use the standard translation.

49

Note that the data on all attached hard drives will be lost when you change from one scheme
to another. You should use extended translation only with MS-DOS, Windows 95, Windows
NT (FAT), OS/2 and you do not need to enable this option if you are using another
operating system such as NetWare or UNIX.

Options Enabled (*)

Disabled

4.2.6.4 Host Adapter BIOS
This field enables or disables the SCSI BIOS for all channels. The SCSI BIOS must be

enabled if you want the computer to boot from a SCSI hard disk drive connected to a
channel. In addition, the BIOS must be enabled if you want to use any of the following
options:

Support Removable Disks Under BIOS as Fixed Disks
Extended BIOS Translation for DOS Drives > 1 Gbyte
BIOS Support for More Than 2 Drives
Send Start Unit SCSI Command

If the devices on the SCSI bus are controlled by device drivers (and therefore do not need a
BIOS), you can disable the SCSI BIOS to free memory and shorten the boot time.

Options Enabled (*)

Disabled

4.2.6.5 Support Removable Disks Under BIOS as Fixed Disks
This field specifies which removable-media drives are supported by the SCSI BIOS. If a

removable-media SCSI device is handled by the BIOS, do not remove the media while the
drive is on or you might lose data.

Options Boot Only (*)

All Disks
Disabled

4.2.6.6 Display <Ctrl><A> Message During BIOS Initialization
This field turns on or off the “Press <Ctrl><A> for SCSISelect ™ Utility !” prompt at boot.

Options Enabled (*)

Disabled

50

4.2.6.7 BIOS Support for Bootable CD-ROM
When enabled, the SCSI controller supports booting from a CD-ROM drive.

Options Enabled (*)

Disabled

4.2.6.8 BIOS Support for Int 13 Extensions
This field enables or disables support for disks with more than 1024 cylinders. In order to

boot from “El Torito” non-emulation CD-ROM, this field must be set to Enabled.

Options Enabled (*)

Disabled

4.3 SCSI Disk Utilities

When this option is selected, SCSISelect scans the SCSI bus to determine the devices installed and
displays a list of all SCSI Ids and the devices assigned to each ID. Once you select a specific ID, a
small menu appears, displaying two options: Format Disk and Verify Disk Media.

4.3.1 Format Disk

A disk drive must have a low-level format before you can use the operating system’s partitioning
and high-level formatting utilities, such as MS-DOS fdisk and format. Most SCSI drives are
preformatted and do not need to be formatted again. If a drive is not preformatted, you can use
SCSISelect’s Format Disk option to perform a low-level format on the drive.

A low-level format destroys all data on the drive and you can not abort a low-level format once it
starts.

4.3.2 Verify Disk Media

The Verify Disk Media option scans the selected device’s media for defects. If the utility finds bad
blocks, it prompts you to reassign them so they are no longer used.

Press <Esc> at any time to abort the utility.
