1.8 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 1.8.1 Software Error Messages Software error messages are returned by your operating system or application.
Table 1-4 System Error Messages Message Action Diskette Drive Controller Error or Not Installed Check and connect the control cable to the diskette controller. 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.
Table 1-4 System Error Messages Message Memory Error at: MMMM:SSSS:OOO (W:XXXX, R:YYYY) Action Check DIMMs on the system board. Contact your dealer. where: M: MB, S: Segment, O: Offset, X/Y: write/read pattern Memory Size Mismatch CPU Clock Mismatch 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.
1.8.3 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. Run Setup.
Chapter 2 Setup 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. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM. If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS.
