Chapter 1 System Board
1.1 Features
This high-performance system board supports the Intel Pentium II CPU running at 233 up
to 450 MHz. Integrated with the Intel 440BX system controller, which consists of the PCI
controller and the PCI/ISA IDE accelerator (PIIX4), the system combines the new
generation of Pentium II power with unmatched graphics performance.
The system controller host bus interface supports a Pentium II processor with 66 or 100
MHz external front side bus frequency. It also provides support for ECC synchronous
DRAM (SDRAM) 168 pin DIMMs.
The PIIX4 is a multifunction PCI device controller implementing system functions
including PCI IDE and universal serial bus (USB) host/hub. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
The system board utilizes both the ISA and the PCI local bus architecture. Two ISA, five
PCI bus slots (including one PCI/ISA shared slot), and one AGP slot reside on the system
board.
Three memory banks composed of 168-pin dual inline memory module (DIMM) sockets
support a maximum system memory of 384 MB using 128-MB DIMMs.
The system board also supports the USB (Universal Serial Bus) interface, and other
standard features such as two UART NS16C550 serial ports, one enhanced parallel port
with an Enhanced Parallel Port (EPP)/Extended Capabilities Port (ECP) feature, a diskette
drive interface, and two embedded hard disk interfaces.
Index

1.2 Major Components
The system board has the following major components:
• A single edge contact (SEC) CPU connector that supports Pentium II processors
running from 233 up to 450 MHz
• Three DIMM sockets that accept 16-, 32-, 64-, and 128-MB SDRAM DIMMs
• Two ISA, five PCI slots
• 256-KB Flash ROM for system BIOS
• Enhanced IDE hard disk and diskette drive interface
• System controller chipset
• External ports:
• Two USB connectors
• One SPP/ECP/EPP high speed parallel port
• PS/2 keyboard and mouse ports
• Two high speed serial ports

1.5 Installing Components
The following sections describe how to install components into the system board,
including how to install a Pentium II processor, and how to upgrade system memory.
Before beginning the installation, please take a moment to read the sections below. They
contain important ESD precautions and pre- and post-installation instructions.
1.5.1 ESD Precautions
Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards,
and other components. Always observe the following precautions before you install a
system component.
1. Do not remove a component from its protective packaging until you are ready to
install it.
2. Wear a wrist grounding strap and attach it to a metal part of the system unit before
handling components. If a wrist strap is not available, maintain contact with the
system chassis throughout any procedure requiring ESD protection.
1.5.2 Pre-installation Instructions
Always observe the following before you install a system component:
1. Turn off the system power and all the peripherals connected to the unit before
opening it. Unplug the power cord from the unit.
2. Open the system according to the instructions in Chapter 3, System Housing.
3. Follow the ESD precautions in section 1.5.1 before handling a system component.
4. Remove any expansion boards or peripherals that block access to components you are
installing.
5. See the following sections for specific instructions on the component you wish to
install.
AcerPower Minitower (M11E/IDCATX-2) User's Guide
Do not attempt the procedures described in the
following sections unless you are a qualified
service technician.
1.5.3 Post-installation Instructions
Observe the following procedures after installing a system component:
1. Check that the components are installed according to the instructions in their
respective sections.
2. Make sure you have set all the required jumpers. See section 1.3 for the correct
jumper settings.
3. Replace any expansion boards or peripherals that you removed earlier.
4. Replace the system cover.
5. Connect the necessary cables and turn on the system.

1.6 Removing a Pentium II Processor
Observe the ESD precautions (section 1.5.1)
when installing or removing a system component.
Follow these steps to remove the Pentium II CPU module from the slot.
1. Remove the fan connections. See Table 1-2.
2. Unlock the latches that secure the processor module.
Figure 1-4 Unlocking the Module Latches
2. Firmly hold the processor module and pull it out of the socket.
AcerPower Minitower (M11E/IDCATX-2) User's Guide
Figure 1-5 Removing the Pentium II Processor
Index
xxvii
1.7 Installing a Pentium II Processor
Observe the ESD precautions (section 1.5.1)
when installing or removing a system component.
Follow these steps to install a Pentium II processor.
1. Remove the Pentium II processor from its protective packaging. Make sure that the
latches on the sides of the module are not pressed.
2. With the processor card edge pointing downward, align the processor to the posts of
the retention mechanism. The processor will only fit one way. Be sure to orient the
processor properly.
The system settings are configured at the factory
for the correct CPU frequency/ Memory DIMM
combination. If you upgrade the CPU frequency
to 350, 400, or 450 MHz, the memory controller
requires PC-100 DRAM DIMMs. Your system
will not work properly if you use standard
DIMMs with the higher speed CPUs. All of the
installed DIMMs must have the same
capabilities.
After upgrading the CPU you must run Setup (see
section 2.1) and change the ‘CPU multiple’
parameter to the correct multiplier for your new
CPU (see section 2.10.3).

1.8 Memory Upgrade
The three 168-pin sockets onboard support synchronous DRAM DIMMs. You may install
16, 32, 64, or 128-MB DIMMs for a maximum of 384-MB system memory. Each of the
sockets represents one independent bank. This allows you to install DIMMs with different
capacities in each bank.
1.8.1 Memory Configurations
Table 1-3 lists some system memory configurations. You can combine DIMMs with
various capacities to form other combinations.
