connector.
3.2 L2 Cache
The L2 cache is integrated in the Intel 810E processor. The private L2
cache bus is not connected to package pins; rather its signals are routed
between the two cavities using standard package techniques.
3.3 DMA Channels
There are seven DMA channels available on the motherboard. Only
DMA2 is used by the floppy controller. In the case that ECP mode on
the parallel port is utilized, DMA1 or DMA3 will be used.
3.4 BIOS
The BIOS on the LI7WM motherboard provides the standard BIOS
functions plus the following additional feature:
Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
3.5 Onboard Multi-I/O
Onboard AC97 Codec with external connectors for Line
out, Line in, Mic, and Game port.
3.6 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
addresses, which also becomes the identity of the device. There is a
total of 1K port address space available. The following table lists the
I/O port addresses used on the motherboard.

PIO mode 3/4 and bus mastering Ultra DMA/33 and DMA/66. The
peak transfer rate of PIO mode 3/4 can be as high as 17MB/sec. Using
HDDs that support Ultra DMA/33, the peak transfer rate can reach 33
and 66MB/sec. There are two IDE connectors -primary IDE and
secondary IDE. With two devices per connector, up to four IDE devices
can be supported.

3.10 Onboard VGA
The Intel 810E chipset is the result of new design approach to optimize
the shared memory architecture while maintaining the cost benefits of
integration through Direct AGP and Dynamic Video Memory
Technology.
a. Direct AGP
Direct AGP delivers AGP class graphics performance to PCs at
reduced cost. Rather than simply combining two semiconductor cell
libraries for component reduction, Intel architects combined the 2D and
3D video capabilities with the memory control unit. This functional
overlap within the Graphics and Memory Controller (Intel® 82810E)
enables Direct AGP. Direct AGP provides an integrated graphics part
with the capability to make direct memory set-up calls (similar to those
associated with standard AGP protocol) to system memory. Direct AGP
calls can dynamically allocate and de-allocate system memory for
complex 3D textures, preserving the benefits of standard AGP add-in
solutions.

Chapter 3 Hardware Description
14 LI7WM User’s Manual
b. Dynamic Video Memory Technology
Dynamic Video Memory Technology (DVMT) enables breakthrough
graphics and memory performance for all PC segments through Direct
AGP and highly efficient memory use. DVMT ensures the most
efficient use of all available memory –regardless of whether a frame
buffer is present or the size of the main memory–for maximum 3D
graphics performance. DVMT also responds to application
requirements by automatically allocating the proper amount of display
and texturing memory. For example, a 3D application might require
more texture memory to enhance the richness of 3D objects. The
operating system (OS) views the Intel 810 and 810E chipset driver as
an application which uses Direct AGP to request re-allocation of
additional memory for 3D applications and returns memory when not
required. DVMT is highly scalable —as additional memory is added to
the system, more memory will be available to enhance 3D applications.
DVMT works dynamically and modulates the bandwidth available to
the CPU, graphics and I/O interface, through the intelligent arbitration
built into the Intel 82810E. This hard-coded logic evaluates the
operating environment and prioritizes traffic to maximize bandwidth
for memory intense multimedia applications.
c. Memory Usage with DVMT
The operating system requires allocation of up to 1Mbyte of system
memory to support legacy VGA. System properties will display up to
1Mbyte less than physical system memory available to the operating
system. The graphics driver for the Intel 810E/810 chipsets
configurations will request up to 4Mbyte of memory from the OS to
implement a maximum 1024 x768 screen resolution, 2Mbyte for a
command buffer and 4Mbyte used for z-buffering. For high-end 3D
applications, the drivers request allocation of system memory from the
OS for graphics textures. When the 3D application is closed, the O/S
will re-allocate system memory back for generic use.
3.11 TV-Out
Chrontel’s CH7007 digital PC to TV encoder is a stand-alone
integrated circuit which provides a PC 99 compliant solution for TV
output. Suggested application use with the Intel 810 chipset and Intel
810E chipset. It provides a universal digital input port to accept a pixel
data stream from a compatible VGA controller (or equivalent) and
converts this directly into NTSC or PAL TV format.

4.1 CPU Frequency Selection
Setting CPU Speed in the BIOS Setup
The LI7WM motherboard allows users to set the CPU speed
through the BIOS Setup. The parameters used in configuring
the CPU speed include CPU Clock Multiplier (X3, X3.5, X4,
X4.5, X5, X5.5, X6, X6.5, X7, X7.5, X8) and CPU Clock
(66MHz, 68MHz, 75MHz, 83MHz or 100MHz, 103MHz,
112MHz, 133MHz).
In the initial setup, the system automatically detects the base
Frequency of the CPU (66MHz or 100MHz/133MHz). Under
the under CPU Speed Setting section, use the ↑and ↓keys to
easily change the CPU speed or press the PageUp or
PageDown key to see more options.
Overclocking could cause the system not to boot in the
process of setting the CPU speed. When this happens, turn
off the computer by pressing the power button and turn it on
again by pressing the Insert key and the power button
simultaneously. When the system is turned on, press the
Delete key to enter BIOS Setup and configure the CPU
speed.
4.2 Clear CMOS Select: JP5
Use JP5, to clear the contents of the CMOS RAM. Do not clear
the CMOS RAM unless it is absolutely necessary. Before clearing
