Chapter 4: Troubleshooting
4.1 Troubleshooting Procedures
Use the following procedures to troubleshoot your system. If you have followed
all of the procedures below and still need assistance, refer to the "Technical
Support Procedures" and/or "Returning Merchandise for Service" section(s) in
this chapter.
No Video
If you do not have video, follow the Troubleshooting Flowchart on the next
page.
1. Check for missing jumpers or improper installation of the ROM BIOS.
2. Make sure the video card and its jumper setting (as appropriate) match the
monitor type.
3. Check to make sure that all peripheral cards are properly installed in their
slots.
4. The I/O Bus speed should be running in the standard 8 MHz range.
5. Use the speaker to determine if any beep codes exist. Refer to the end of
this manual for details about beep codes.
Note: If you are a system integrator, VAR, or OEM, a POST diagnostics card is
recommended for Port 80h codes. (Please visit our Web Site for detailed
information.)
Memory Error/Parity Error
If you encounter memory or parity errors, follow the procedures below.
1. Check to determine if SIMM modules are improperly installed.
2. Make sure that different types of SIMMs have not been installed in the
same bank. (e.g. a mixture of 265KB x 9 and 1 MB x 9)
3. Determine if different speeds of SIMMs have been installed in the
same or different banks, and the BIOS setup is configured for the
slowest speed of RAM used. It is recommended to use the
same RAM speed for SIMMs in different banks.
