[. . . ] A memory error message appears, indicating that the total memory does not match the value stored in CMOS. A warning message Press appears indicating an incorrect memory configuration. Press twice to exit and reboot the system. 2. 3. The system boots with the new memory configuration. 1. 5 IDE Hard Disk Support The system board supports four IDE hard disks, or any other IDE devices, through the two onboard PCI IDE interfaces. Follow the instructions in the housing installation manual on how to install a hard disk in the system. Connect the cables according to the IDE hard disk configuration in Table 1-8. Table 1-8 IDE Hard Disk Configuration Master Hard disk 0 Hard disk 2 Slave Hard disk 1 Hard disk 3 IDE Connector Channel 1 Channel 2 System Board 1-15 1. 6 CPU Installation The system board comes with a zero-insertion force (ZIF) CPU socket for easy installation. Follow these steps to install a Pentium CPU: 1. Make sure that the notched corner of the CPU matches the pin 1 indicator on the socket. Be careful not to bend any pins. 3. Pull down the socket lever. STEP 1 Notched Corner STEP 2 STEP 3 Pin 1 Indicator Figure 1-7 4. Installing a Pentium CPU Set the CPU jumpers accordingly. Refer to Table 1-2. 1-16 User's Guide 1. 7 Video Memory Upgrade Larger video memory allows you to display higher resolutions and more colors. The system board comes with a 1-MB video memory onboard upgradable to 2 MB. Follow these steps to upgrade the video memory: 1. Remove all PnP cards installed in the system, if any. Enter BIOS utility and set the Reset Resource Assignment parameter to Yes to clear the resource data assigned to the PnP devices. 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. 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. 1-28 User's Guide 1. 12 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. 12. 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. 12. 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.

If not, replace the RTC chip. System Board 1-31 1. 12. 3 Correcting Error Conditions As a general rule, if an error message says "Press F1 to continue, " it is caused 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. [. . . ]
