[. . . ] Open the system according to the instructions in the housing installation manual. Follow the ESD precautions in section 1. 4 before handling a system component. Remove any expansion boards or peripherals that block access to the SIMM sockets or CPU socket. See the following sections for specific instructions on the component you wish to install. 1-8 User's Guide Do not attempt the procedures described in the following sections unless you are a qualified service technician. 1. 6 CPU Installation The system board comes with a zero-insertion force (ZIF) CPU socket for easy installation. [. . . ] Align pin 1 of the CPU with hole 1 of the socket. The topmost label indicates the CPU frequency and the cache size. Cache size supported CPU frequency Hole 1 Pin 1 indicator Figure 1-3 Locating Pin 1 of the CPU and Hole 1 of the Socket System Board 1-9 3. 4. Gently insert the CPU into the socket. Pull down the socket lever to lock the CPU into the socket. Step 1 Step 3 Step 4 Figure 1-4 5. Installing a CPU Attach the heatsink and fan to the CPU. Figure 1-5 1-10 Attaching the Heatsink and Fan to the CPU User's Guide 6. Plug in the fan cable to the two-pin fan connector marked JP2 on the system board. 1. 7 Memory Configurations The system board comes with six 72-pin SIMM sockets that support 4MB and 16-MB single-density SIMMs and 8-MB and 32-MB doubledensity SIMMs, with or without the Extended Data Out (EDO) function. Table 1-3 lists the possible memory configurations. 1. 7. 1 Rules for Adding Memory · · · Use only one type of SIMM in a given bank. You may combine different types of SIMMs for a memory configuration as long as the SIMMs in each bank are of the same type. For example, for a total memory of 8 MB, install two 4-MB SIMMs into the sockets marked S1 and S2 or S3 and S4. You can not use an 8-MB SIMM alone for an 8-MB memory. Always install SIMMs from the outermost socket first. For example, socket S1 before socket S2, or socket S3 before socket S4. Use Windows 95 or ICU 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. 3. 5. BIOS detects and configures only PnP cards. 6. This time PnP BIOS automatically configures the PnP ISA and PCI cards with the remaining free IRQs. System Board 1-17 1. 10 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. Make sure you have set all the required jumpers. See section 1. 3. 2 for the correct jumper settings. Replace any expansion boards or peripherals that you removed earlier. Connect the necessary cables and turn on the system. 1. 11 Error Messages Do not continue using the computer if you receive an error message of any type. Note the message and take corrective action. This section explains the different types of error messages and corresponding corrective measures. [. . . ] There are two general types of error messages: · · Software System 1. 11. 1 Software Error Messages Software error messages are returned by your operating system or application. These messages typically occur 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. 1-18 User's Guide 1. 11. 2 System Error Messages A system error message indicates a problem with the computer itself. A message of this type normally appears during the power-on self-test, before the operating system prompt appears. [. . . ]
