System Board 1-1
1.1 Features
The V58LA is an all-in-one Pentium-based system board that utilizes
the PCI local bus architecture. It is capable of offering multimedia and
network functions by simply integrating a VGA controller with 3D
support, a Sound Blaster-compatible audio chip, and a Fast Ethernet
controller.
The system memory is expandable to 256 MB via two onboard 168-pin
DIMM (double in-line memory module) sockets. To further enhance
system performance, the board also comes with 256-/512-KB
pipelined-burst second-level cache and 1/2/4-MB video memory.
Standard onboard I/O interfaces comprise of two UART 16C550 serial
ports, a parallel port with Enhanced Parallel Port (EPP)/Extended
Capabilities Port (ECP) feature, PS/2 keyboard and mouse ports, and
VGA port. Two Universal Serial Bus (USB) interfaces are added to the
design to enable the system to support more peripherals. For full
multimedia support, video, audio and network interfaces are also
provided.
Other special features supported are Hardware Monitoring and
Wake-on Ring-in functions. For details, read the following sections.
The system is fully compatible with Windows 95, Windows NT,
NetWare, MS-DOS V6.X, OS/2, and UNIX operating systems.

1.5 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 unit throughout any
procedure requiring ESD protection.
1.6 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.
2. Open the system according to the instructions in the housing
installation manual.
3. Follow the ESD precautions in section 1.5 before handling a
system component.
4. Remove any expansion boards or peripherals that block access
to the DIMM sockets or CPU socket.
5. See the following sections for specific instructions on the
component you wish to install.
Do not attempt the procedures described in
the following sections unless you are a
qualified service technician.

System Board 1-11
1.7 Installing Memory
The system memory is upgradable to a maximum of 256 MB via two
168-pin DIMM sockets onboard. These DIMM sockets accept 8, 16,
32, 64, and 128-MB, 3.3V SDRAMs. See Figure 1-1 for the location of
the DIMM sockets. Section 1.7.1 tells how to install DIMMs.
Table 1-6 lists the possible memory configurations.

1.7.1 Installing a DIMM
Follow these steps to install a DIMM:
1. Align pin 1 of the DIMM with pin 1 of the socket. Pin 1 is labeled
1 on both of the DIMM and the socket.
2. Gently push the DIMM until the holding clips lock the DIMM into a
vertical position.
Figure 1-3 Installing a DIMM
Be careful when inserting DIMMs. Forcing a
DIMM in or out of a socket can damage the
socket or the DIMM (or both).

1.7.2 Removing a DIMM
To remove a DIMM:
1. Press the holding clips on both sides of the socket outward to
release the DIMM.
2. Gently pull the DIMM out of the socket.

the previously installed CPU first.
Follow these steps to remove the CPU:
1. Locate the CPU socket with CPU mounted on the system board.
2. Detach the fan cable connector.
3. Pull up the socket lever. The CPU pins will be automatically
released from the socket holes.
4. Detach the CPU from the socket.

System Board 1-15
1.9.2 Installing the Upgrade CPU
Observe the ESD precautions when installing
components. See section 1.5.
Before you proceed, make sure that there is no CPU installed in the
CPU socket.
Follow these steps to install the upgrade CPU:
1. Pull up the socket lever.
2. Insert the CPU, making sure that pin 1 (indicated by a notched
corner) of the CPU connects to hole 1 of the socket.
3. Pull down the socket lever to lock the CPU into the socket.
