&KDSWHU System Board 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.
1.2 Major Components The system board has the following major components: • • • • • • • • • • • • • • • • • 1-2 A ZIF (zero insertion force) socket that supports 3.3V Intel Pentium P54C/P55C processor running at 90/60, 100/66, 120/60, 133/66, 150/60, 166/66, 200/66, or 233/66 MHz.

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.
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. 2 1 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. 2 1 Figure 1-4 1.7.3 Removing a DIMM Reconfiguring the System The system automatically detects the amount of memory installed. Run Setup to view the new value for total system memory and make a note of it.
1.8 Second-level Cache The board may come with either 256-KB or 512-KB pipelined-burst second-level cache. Refer to the following table for the possible cache configurations. Table 1-7 Second-level Cache Configurations Cache Size Data RAM (12 ns) 256 KB 32K x 32 x 2 pcs. 512 KB 64K x 32 x 2 pcs.

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. notched corner hole 1 Figure 1-5 4.

1.12 Expansion Cards 1.12.1 Installing a Riser Card A riser card is a card that contains the PCI and ISA slots. This enables you to add functions to your system further enhance its performance. To install a riser card: 1. Locate the riser card slot on the system board. 2. Gently insert a riser card into the slot. Make sure that the card is properly seated into the slot.
1.12.2 Installing a PCI Card To install a PCI card: 1. Locate the PCI slot(s) on the slot board. 2. Remove the bracket on the housing opposite to the empty PCI slot. 3. Insert a PCI card into the slot. Make sure that the card is properly seated. 4. Secure the card to the housing with a screw. When you turn on the system, BIOS automatically detects and assigns resources to the PCI devices.
1.12.3 Installing ISA Cards Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA cards, make sure that the IRQs required by these cards are not previously assigned to PCI devices to avoid resource conflicts. Follow these steps when installing ISA cards: 1. Remove all PnP cards installed in the system, if any. 2. Install non-PnP ISA cards. 3. Turn on the system. 4. Use Windows 95 or ICU to manually assign the appropriate IRQs to the cards.
1.13 Post-installation Instructions Observe the following after installing a system component: 1. See to it that the components are installed according to the stepby-step instructions in their respective sections. 2. Make sure you have set all the required jumpers. See section 1.4.2. 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.
1.15 Hardware Monitor Function The Hardware Monitor function of the system board allows you to check the system resources, either locally or in a computer network, via software such as ADM (Advanced Desktop Management) or Intel LDCM (LAN Desk Client Manager) ). ADM and Intel LDCM are desktop management programs that offer SMART (System Monitoring Analysis and Reporting Technology) monitor function for checking local or network connected systems.
1.18 Error Messages In the event that you receive an error message, do not continue using the computer. Note the message and take corrective action immediately. This section describes the different types of error messages and suggests corrective measures. There are two general types of error messages: • • Software System 1.18.1 Software Error Messages Software error messages are returned by your operating system or application.
