Overview
Thank you for purchasing Iwill LE370 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.

Medium sized Phillips head screwdriver
A 3/16 inch nut driver or wrench
2.3 Installation procedures
2.3.1 Processor (Socket 370 and FAN1)
The motherboard supports socket 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 300 MHz to 466 MHz, or more.
CPU Cooler is required to be placed on top of the CPU all the time to prevent CPU from
over-heat.
Signal of FAN1 header (processor fan header)
Pin 1 Ground
Pin 2 +12 V
Pin 3 SENSE
Note: Processor cooler is always required to prevent over-heat.

2.3.2 Setting CPU speed
The CPU can be setup through a programmable switch that replaces traditional manual hardware
configuration. This feature allows the user to complete more easily the installation procedures. The
CPU must be setup according its specifications. You can reference Appendix A or user’s manual in
the Power Installer CD.
2.3.3 Main memory (DIMM0--2)
The motherboard has four dual inline memory module (DIMM) sockets, which supports memory
size from 8 MB to 768MB 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 DIMM with gold-plated contacts
3.3 V memory module only
ECC logic detects multiple-bit errors and corrects single-bit errors (SDRAM)
Unbuffered SDRAM, or 60-ns 3.3 V EDO DIMM
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.
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.

18
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".
For Windows 95 :Upgrade to Windows 95 OSR 2.1.
Install DirectX 6 from Microsoft.
