[. . . ] Do not remove a component from its protective packaging until you are ready to install it. 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. 4. 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. [. . . ] Both are capable of increasing the performance of 32-bit software and multimedia applications. 1. 6. 1 Removing a Processor Card Observe the ESD precautions when installing or removing a system component. Before you can replace or upgrade your processor, you need to remove the previously installed processor on the system board. Follow these steps to remove the processor card: 1. Press the latches on both sides of the processor to release it from the retention mechanism. You will hear a click sound once the latch is released. Figure 1-5 2. Pressing the Latches Pull the processor to totally detach it from the CPU connector. System Board 1-13 Figure 1-6 Removing a Processor Card 1. 6. 2 Installing a Processor Observe the ESD precautions when installing or removing a system component. Before you proceed, make sure that there is no processor installed in the CPU connector. Follow these steps to install a processor card: 1. Place the retention mechanism over the CPU connector on the system board. Secure it with the screws that came with the package. 1-14 User's Guide Figure 1-7 2. 4. Installing the Retention Mechanism Remove the processor card from its protective packaging. Make sure that the latches on the sides of the module are not pressed. With the processor card golden fingers pointing downward, align the processor to the posts of the retention mechanism. Lower the processor into to the CPU connector on the system board until the golden fingers touch the connector. Figure 1-8 Installing a Processor Card System Board 1-15 5. Press down the processor until the golden fingers completely fit into the connector and the latches on the sides lock the processor into place. Figure 1-9 Locking the Processor 1. 7 IDE Hard Disk Support The board comes with an enhanced PCI IDE controller that supports PIO mode 4 and Ultra DMA (Direct Memory Access) mode data transfers. Refer to the software documentation for more details on the Hardware Monitoring function. 1. 13 Wake-on Ring-in Function The Wake-on Ring-in function enables the system to resume from suspend mode by monitoring the fax/modem (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 1-2 for the location of the Modem ring-in connector on the system board. 1-24 User's Guide 1. 14 Wake-on LAN Function The system supports the Wake-on LAN feature via the onboard Wake-on LAN connector. This special feature allows the system to suspecial feature allows the system to be turned on via a network. Common network functions, such as remote access, file sharing, etc. are also supported. 1. 15 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. 15. 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. 1. 15. 2 System Error Messages A system error message indicates a problem with the computer itself. [. . . ] Change the I/O expansion ROM address.
