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 8-
bits of information to report the year and can only hold the last two digits of a year in packed BCD
format. For example, 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 4-digit year yields 1900, not 2000. Any applications which compare dates, or uses relative dates
to perform functions will see incorrect dates.

All 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 sources.

Quick Installation
Several easy installation steps will be described in this chapter to help the experienced users with
quick installation. If you are a beginner, or need to know more about this product, please refer to
Chapter 3.
Note: Please reviews 1.3 Motherboard Components Placement graphic for reference.

Warning: Users must follow these guidelines to ensure the BD100 Plus is protected during
installation.
a. Make sure your computer is unplugged whenever working with inside components.
b. Beware of Static electricity! Either wear anti-static wrist straps, or ensure that you
touch a safely grounded object (such as a metal desk/table). Don’t handle components
near high static objects (i.e. carpets, wool/ acrylic sweaters, etc.).
c. Pick up components by their bodies. Try not to touch IC chips, connectors or leads.
Don’t handle components any more than necessary.
d. Keep all magnets away from both your hard and floppy disk drives, especially magnetic
screwdrivers. Keep both floppy and hard disks apart if disassembled.
e. Keep water and liquids away from your computer and its components.

Step 1. Install processor

This process is for motherboards already equipped with the universal retention mechanism.

For Pentium II processors:

a. Lift each of the two retention mechanism brackets so that they stand fully upright.
You should hear a soft “click” sound once each bracket is in the correct upright
position.
b. With the CPU fan facing the DIMM sockets, insert the CPU horizontally into the
retention mechanism, sliding both edges in simultaneously and as “evenly” as
possible. Then, press down gently yet firmly so that the CPU is fully inserted
correctly into the socket.
c. Locate the two CPU lock switches, which are on the top, one on each side of the
CPU just above its respective bracket. With the CPU fan facing you, use both
hands and grasp the CPU, placing each thumb on top of each lock switch. Then,
at the same time “flip” each lock switch outward in opposite directions (both
away from the CPU fan). You should hear two “click” sounds, one from each
switch. This indicates the CPU is secured into place.
d. To release CPU, grasp the CPU (in the same manner in “c” above) and push both
lock switches inward (toward the CPU fan). You should hear two “click” sounds,
one from each switch. Lift CPU upward and out of the socket.

higher.

This process is for motherboards already equipped with the universal retention mechanism.

For Pentium II processors:

a. Lift each of the two retention mechanism brackets so that they stand fully upright.
You should hear a soft “click” sound once each bracket is in the correct upright
position.
b. With the CPU fan facing the DIMM sockets, insert the CPU horizontally into the
retention mechanism, sliding both edges in simultaneously and as “evenly” as
possible. Then, press down gently yet firmly so that the CPU is fully inserted
correctly into the socket.
c. Locate the two CPU lock switches, which are on the top, one on each side of the
CPU just above its respective bracket. With the CPU fan facing you, use both hands
and grasp the CPU, placing each thumb on top of each lock switch. Then, at the
same time “flip” each lock switch outward in opposite directions (both away from
the CPU fan). You should hear two “click” sounds, one from each switch. This
indicates the CPU is secured into place.
d. To release CPU, grasp the CPU (in the same manner in “c” above) and push both
lock switches inward (toward the CPU fan). You should hear two “click” sounds,
one from each switch. Lift CPU upward and out of the socket.

For Pentium III/Celeron processors:

a. Follow steps “a” ~ “b” above.
b. Locate the two sliding locks on each bracket. Read the writing on each lock:
“OPEN” and “LOCK”. To lock, use your index finger and thumb, grasp each lock,
and gently slide upward. This may be done simultaneously with two hands, or one
at a time. Once each lock has been fixed upward, the CPU is secured into place.

The BD100 Plus motherboard has four Dual Inline Memory Module (DIMM) sockets, which support
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 bits when accessing memory.

The BD100 Plus 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
Note: 3.3 V EDO and SDRAM DIMMs cannot be installed together (at the same time) on the BD100
Plus motherboard

21
Memory can be installed in DIMM sockets without any order restrictions. 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.
Note 2: The Serial Presence Detect (SPD) information is highly recommended on all 100
MHz DIMMs for the BD100 Plus 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 displayed if any DIMMs
installed on this motherboard have no SPD EEPROM. If this is the case, the system might
become unstable without correct timing parameters.

3.3.4 Accelerated Graphics Port (AGP)

The Accelerated Graphics Port (AGP) is a high-performance bus, especially for graphic-intensive 3D
applications. AGP is independent of the PCI bus, and is intended for exclusive use with graphics
devices. The AGP supports AC timing for 133 MHz data transfer rates, allowing data throughput of
533 MB/sec.
The most important feature of AGP is DIME (Direct Memory Execute). DIME needs to allocate
some system memory via the OS to access large textures outside the local graphic memory of the card.
In order to take advantage of the DIME feature, some software components should be installed or
upgraded within your system.
For Windows NT 4.0: Upgrade to "Windows NT 4.0 Service Pack 3" or later versions
For Windows 95: Upgrade to Windows 95 OSR 2.1 or later versions
Install DirectX 5 or later versions from Microsoft

System BIOS Setup

4.1 Introduction
The BD100 Plus motherboard uses AWARD BIOS, which is stored in flash memory and can be
upgraded using the appropriate software 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 after the power has been turned off.

4.1.1 Upgrade BIOS

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

4.1.2 Recovering BIOS Data

Some types of conditions can destroy the BIOS. Nevertheless, the BIOS can be recovered from a
diskette. To recover BIOS, you must create a bootable diskette, then copy the recovery files onto it.
The recovery files are available from Iwill.
Note: No video is displayed during the recovery process.

4.1.3 Enter BIOS setup program

Power-on the system by either pressing the Power-On button, or by using any of the power-on
features provided by the BD100 Plus motherboard. Then, press the <Del> key after the Power-On
Self Test (POST), and before the scanning of IDE devices. Simply look for the message “Press DEL
to enter SETUP” displayed at the bottom of the screen during the boot up process. If the message
disappears before you’ve had a chance to 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.

29
4.1.4 Using BIOS setup program
The following table shows the function keys available for each menu screen.
áUp Move to the previous field
âDown Move to the next field
ßLeft Move to the field on the left hand side
àRight Move to the field on the right hand side
<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> 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 you
DO NOT update your BIOS if the system works perfectly.
DO NOT change any setting unless you fully understand what it means.
If the system does not work smoothly after changing the BIOS settings, follow the procedures
described previously, enter the BIOS setup program, then load the original manufacturer default
settings.

If the system is no longer able to boot after changing the settings, the only way to recover it is to clear
the data stored in RTC CMOS. To reset the RTC CMOS data, take the JP1 jumper cap off pins 1-2,
place onto pins 2-3, and then place back onto pins 1-2 again. This will return the RTC to the default
setting. Then, get into the BIOS setup program (see 4.1.3 above), choose LOAD SETUP
DEFAULTS, and select the original manufacturer default settings in your CMOS.

4.2 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: A brief description of each highlighted selection appears at the bottom of the screen.

4.10 IWILL SMART SETTING

Warning: Over-clocking is not guaranteed. Users must have substantial knowledge of proper Vcore
settings prior to adjusting CPU speeds. Over-clocking should be done only by experienced engineers
who conduct tests.

In general, when adjusting the CPU frequency, you should select the frequency that matches your
motherboard bus speed. The reason is that your CPU can only communicate with its external
components at the same speed at which the components operate. In other words, if your motherboard
bus speed is 100 MHz, you should start by selecting 100 MHz (as a “base”) to set the CPU frequency.
This frequency is also referred to as the “system bus frequency” or external frequency.

However, the CPU manufacturers make CPUs much faster than the speed of the motherboard system
bus frequency. This is true because most of the operations are done in a small die inside the CPU chip.
This is the CPU internal frequency. For example, a 400 MHz CPU actually means the internal
frequency runs at 400 MHz.

To understand the term multiplier, and how it applies to setting your CPU frequency, here’s an
example: If you purchase a 400 MHz CPU, and your motherboard runs at 100 MHz system bus speed,
adjust your CPU frequency by selecting 100 MHz (system bus frequency) x 4 (multiplier), which
equals 400 MHz (your CPU frequency). Or, to install the same 400 MHz CPU into motherboard with
66 MHz system bus speed, you may be select 66 MHz (system bus frequency) x 6 (multiplier),
which equals 400 MHz (your CPU frequency). However, the fact is, a higher system bus frequency
runs faster and has a much better performance than a slower system bus frequency.

4.10.1 CPU Speed

This field allows user to adjust CPU speed.
Options 300 (66x4.5) / 333 (66x5) / 366 (66x5.5) / 400 (66x6) / 433 (66x6.5) / 466 (66x7) /

5.6 Installing the Suspend to Disk utility on your BD100 Plus

5.6 motherboard
Suspend to Disk is an energy-saving feature that allows you to temporarily power off your system (i.e.
when you step away from your computer for a meeting, errand, etc.), then return to the original screen
(when the screen was last on) to resume your work the next time you power-on the system. This
feature is fast and efficient, especially if your system is handling a small memory size.

Although the Suspend to Disk utility can be installed without an operating system, it is highly
recommended that you first install an operating system before installing Suspend to Disk. You must
first make a “Suspend to Disk” diskette to use for installation. Insert the Power Installer CD into
your CD-ROM, select Make Driver Diskette from the menu, and carefully follow the instructions to
make a driver diskette. Please see Chapter 5.2 in the BD100 Plus manual to create a driver diskette
without an operating system.

System Requirements for installing Suspend to Disk:

1. Suspend to Disk utility only works with IDE hard disk drives. You cannot use this utility with any
SCSI device because the system BIOS controls IDE devices, but cannot control SCSI devices.
2. This feature works fine with Windows 95/98, and Windows NT FAT file systems, but does not
work with Windows NT NTFS file system. This utility also does not support ACPI modes.
3. This feature works fine with APM compatible PCI/AGP VGA and Sound Blaster compatible
cards and drivers.
4. The Intel Bus Master IDE driver is not fully compatible with Suspend to Disk. If this causes
some problems, please uninstall the drivers, or do not use Suspend to Disk.
5. Whether you select file or partition method, please make sure that you have enough free HDD
space for creating this hidden file or partition. Ex: if you have 64MB system memory and 4MB
of VGA memory, you need at least 68MB (64MB + 4MB) of HDD space. You also have to
reserve some free space for your future memory expansion. For example, if you plan to upgrade
you system memory to 128MB in the near future, then you may reserve a 132MB (128MB+4MB)
space.
6. The following are just some of the many AGP cards that have been tested and approved to work
satisfactorily with Suspend to Disk:

5.6.1 Set-Up Suspend to Disk

Before installing Suspend to Disk utility, please make sure your system is running normally. More
importantly, you must ensure the Suspend to Disk feature has been disabled before installing new
devices, or upgrading your system memory.

Enter BIOS setup

Power-on the system by either pressing the Power-On button, or by using any of the power-on
features provided by the BD100 Plus motherboard. Then, press the <Del> key after the Power-On
Self Test (POST), and before the scanning of IDE devices. Simply look for the message “Press DEL
to enter SETUP” displayed at the bottom of the screen during the boot up process. If the message
disappears before you’ve had a chance to 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.

Set-Up Suspend to Disk in BIOS

a. Select Power Management Setup, move cursor to “Suspend Mode Option”, select “Suspend to
Disk” and move cursor to “Soft-Off by PWR-BTTN”, select “Delay 4 Sec”.
b. Select PNP/PCI Configuration Setup. Then, for “PnP OS Installed” select "NO".
c. Press <F10> to save your setup into BIOS. The system will then automatically re-boot.

5.6.1.1 Enter DOS mode From Windows 95/98/NT

Open your “Programs” file, and select “MS DOS Prompt.”
Once you’ve entered DOS from Windows
a. Type the following:
C:\WINDOWS>lock
Press <Enter>
b. The system will ask, “Are you Ready?” Press “y” for “yes.” Press <Enter>.
c. Insert your Suspend to Disk diskette into your floppy disk drive. (See above).
d. Type the following:
C:\>A:
Press <Enter>
e. Creating a file or partition
There are two ways to store the data into HDD: create a file or partition. You must make

58
 sure you have enough disk space before selecting either option (Please refer to System
Requirements above). Creating a file stores all the necessary information (you may be
working on) into a hidden read-only file within the system hard disk. Creating a partition
allows further protection for you by storing all the necessary information into partition
separate from other files.

Create a file
You may select the file size, or allow the system to automatically select for you.
Automatic Selection
Type the following:
A:\>zvhdd /c /file
(Note one space is between “zvhdd and “/c”, and one space is between “/c” and “/file”)
Press <Enter>
The system will then automatically select file size.
Then, the system will display the following message: “The C:\SAVE2DSK.BIN has been
executed”. The Suspend to Disk utility has been set up.

Enter File Size (Example: You select 100 MB file size)

Type the following:
A:\>zvhdd /c /file /m:100
(Note one space is between “zvhdd and “/c”, between “/c” and “/file”, and between “/file”
and “/m:100”)
Press <Enter>
In this case, the system will use 100 MB file size that you’ve selected.
Then, the system will display the following message: “The C:\SAVE2DSK.BIN has been
executed”. The Suspend to Disk utility has been set up.

Create a partition
Type the following:
A:\>zvhdd /c /partition
(Note one space is between “zvhdd and “/c”, and one space is between “/c” and “/partition”)
The system will start to create and format a partition.

Whether you have selected file or partition options, once the Suspend to Disk utility has been set up,
press any key, and you will automatically return to Windows. Then, you must restart your system in
order to enable the Suspend to Disk feature.

5.6.1.2 Enter DOS command Directly

You may also enter DOS during the re-boot process by pressing the <F8> key after powering
on the system, and selecting “Command prompt only.” If your system normally runs from
DOS, or you have a DOS diskette, simply boot from DOS.
Then, simply follow procedures “c” through “e” (above). Since the system is not controlled
by Windows, it will automatically re-boot.

59
5.6.2 Using Suspend to Disk
There are two ways to use Suspend to Disk:
1. Simply press the power-on button located on the front panel of your computer chassis. Note:
Do not hold the power-on button more than four seconds, because the system will shutdown
immediately, and the Suspend to Disk function will not work.
2. For Windows 95/98/NT, you may use your mouse, “click” on the “Start” icon (located on the
lower left hand corner of your screen). Then, “click” the “Shut Down” option. Finally, select
the “Standby” option.

After selecting either method, the system will automatically enter the Suspend to Disk mode. The
screen will become black for several seconds. Then, the screen will display the percentage of
memory as it is being saved into the hard disk. Once the percentage reaches 100%, the system will
shut down automatically.
To return to the original screen (last used when the system was last on), press the power-on button.
The screen will display the percentage of memory as it is being restored from the hard disk. Once the
percentage reaches 100%, the system will return to the original screen.

5.6.3 Removing Suspend to Disk utility

This process helps disable the Suspend to Disk utility.

5.6.3.1 Delete Suspend to Disk From Windows 95/98/NT
