Overview
Thank you for purchasing Iwill DGL200 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 8-
bit 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 4-
digit 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 Processors (P.Slot 2, S.Slot 2, FAN1/FAN1A and FAN2/FAN2A and
FAN3)
The motherboard supports single or dual Pentium® IIXeon processor. If you are installing two
processors, the following values must be identical for both processors:
L2 cache size and type (ECC or non-ECC)
Operating voltages
Bus and core frequencies
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
400 MHz to 500 MHz.
The Pentium® IIXeon 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 2 connector, a 330-pin edge connector.
When mounted in a Slot 2 connector, the processor is secured by a retention mechanism attached to
the motherboard.
First, screw the main body of Slot 2 retention mechanism to the motherboard then insert the
processor cartridge along the retention mechanism in vertical direction. Finally, attach the
cooler’s power cable to the processor fan header on the motherboard.
Signal of FAN1/2 header (processor fan header)
Pin 1 Ground
Pin 2 +12 V
Pin 3 SENSE
Note 1. Processor cooler is always required to prevent over-heat.
Note 2. The second-level cache is located on the substrate of the S.E.C. cartridge. The cache size
and cacheable memory size are dependent on the processor used.
Note 3. Processor can be installed in either of the two Slot 2 sockets without any order restriction.

18
2.3.2 Processor frequency Selection (JP3)
JP3 is a 2x6-pin jumper block with Easy-jumper cap on it for you to select the processor’s working
speed easily.
400 450 500 RS0 RS1 Processor
ON OFF OFF OFF OFF For Pentium® II 400 MHz
OFF ON OFF OFF OFF For Pentium® II 450 MHz
OFF OFF ON OFF OFF For Pentium® II 500 MHz
Note: This jumper is able to provide more powerful functions, which are reserved for technician’s
special testing purpose only. DO NOT use these functions unless you are an experienced user
and you are willing to take your risk.
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 2 GB with SDRAM. 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
16 / 64 Mbit DRAM technology
Symmetrical and asymmetrical DRAM addressing
Single-sided or double-sided DIMMs
Registered and Unbuffered DIMMs can NOT be installed on the same motherboard
Memory can be installed in DIMM sockets without any order restriction. The memory 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 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.

19
2.3.4 Accelerated Graphics Port (AGP)
The Accelerated Graphics Port (A.G.P.) is a high-performance interconnect, especially for graphic-
intensive 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 or later".
For Windows 95: Upgrade to Windows 95 OSR 2.1.
Install DirectX 6 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.
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.

20
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.
