11.1 Installing a PCI Card

To install a PCI card:
1. Locate the PCI slot(s) on the system 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.

11.2 Installing ISA Cards

Both PnP and non-PnP ISA cards require specific IRQs (Interrupt ReQuests). 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. Turn off the system.
2. Open the system and remove all PnP cards installed in the system, if any.
3. Install non-PnP ISA cards.
4. Turn on the system.
5. Use Windows 95 or ICU (ISA Configuration Utility) to manually assign the appropriate IRQs to the cards. This ensures that BIOS will not use the resources assigned to the non-PnP ISA cards.
BIOS detects and configures only PnP cards.
6. Turn off the system.
7. Locate the expansion slots and install the PnP ISA and PCI cards.
8. Turn on the system. This time PnP BIOS automatically configures the PnP ISA and PCI cards with the available resources.

12 USB

USB (Universal Serial Bus) is a new serial bus design that is capable of cascading low-/medium-speed peripherals (less than 12 Mbps) such as a keyboard, mouse, joystick, scanner, printer and modem/ISDN. With USB, complex cable connections at the back panel of your PC can be eliminated.
The board comes with two USB ports (CN1) . See Figure 1 or Figur e 2 for the location of the ports.

13 Wireless Communication Feature

The system supports Wireless Communication via an onboard infrared interface (CN2 - see Figure 2). This feature enables the system to communicate with SIR (Serial Inf raRed)-aware peripher als without the aid of cables.
The onboard infrared interface is IrDA-compliant, allowing data transfer at a rate of 115.2 k ilobits per second (Kbps) at a m aximum distance of one meter.

14 Hardware Monitoring Function

The Hardware Monitoring function allows you to check the system resources, either locally or in a computer network, by using software such as Intel LDCM (LAN Desk Client Manager). ADM and Intel LDCM are desktop management programs that offer the SMART (System Monitoring Analysis and Reporting Technology) monitor function for check ing local or network connec ted systems . In addition, it also enables the PC products and applications to be OS (operating system) independent.
To enable the Hardware Monitoring function, you need to install Intel LDCM. Contact your dealer for information on the availability of the software. Refer to the software docum entation f or m ore details on the Hardware Monitoring function.

15 Wake-on Ring-in Function

The Wake-on Ring-in function enables the system to resume from suspend mode by monitoring the fax/m odem (or any device of similar type) activities. Any signal or activity detected from the Modem ring-in connector automatically returns the system to normal operation. Refer to Figure 2 for the location of the Modem ring-in connector (CN9) on the system board.

17 Error Messages

There are two general types of error messages:
Software
•
System
•

17.1 Software Error Messages

Software error messages are returned by your operating system or application. These messages typically appear after you boot the operating system or when you run your applications. If you receive this type of message, consult your application or operating system manual for help.

17.2 System Error Messages

A system error message indicates a pr oblem with the computer itself . These messages normally appear during the power-on self-test, before the operating system prompt appears. Table 7 lists the system error messages.

17.3 Correcting Error Conditions

As a general rule, the "Press F1 to continue" error m essage is caus ed by a configuration problem which can be easily corrected. An equipment malfunction is more likely to cause a fatal error, i.e., an error that causes complete system failure.
Here are some corrective measures for error conditions:
1. Run Setup. You must know the correct configuration values for your system before you enter Setup, which is why you should write these values down when the system is correctly configured. An incorrect Setup configuration is a major cause of power-on error messages, especially for a new system.
2. Remove the system cover according to the directions in the system housing installation guide. Check that the system board and any expansion boards are set correctly.
3. Check that all connectors and boards are secure. Consult the system housing installation guide for assistance.
If you have purchased a new hard disk drive and cannot access it, it may be because your disk is not physically formatted. Physically format the disk using the FDISK and FORMAT commands.
If you follow the corrective steps above and still receive an error message, the cause may be an equipment malfunction.
If you are sure that your configuration values are correct and your battery is in good condition, the problem may lie in a damaged or defective chip. Contact an authorized service center for assistance.
