The system boots with the new memory configuration. 2-18 + + .
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 describes the types of error messages and lists their corresponding corrective measures. There are two general types of error messages: • • Software System Software Error Messages Software error messages are returned by your operating system or application.
Message Action Diskette Drive Error Check the CMOS settings in Setup and the diskette drive cable connections. Diskette Drive A Type Mismatch Run Setup and select the proper drive type. Diskette Drive B Type Mismatch Run Setup and select the proper drive type. Equipment Configuration Error Modify DRAM configuration to agree with one of the options in Table 1-3. Hard Disk Controller Error Run Setup. Hard Disk 0 Error Check all cable connections. Replace hard disk.
Message Memory Size Mismatch CPU Clock Mismatch Action Check the memory size based on the system specifications. Check the internal cable connections. If you are sure that connections and values are correct, ignore the message. If the message reappears, ask for technical assistance. Onboard Serial Port 1 Conflict Run Setup and disable the port. Onboard Serial Port 2 Conflict Run Setup and disable the port. Onboard Parallel Port Conflict Run Setup and disable the port.
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. Run Setup.
Chapter 3 BIOS Utility Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a Run Setup message.
