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 P.25.
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 at 8 MHz.
5. Use the speaker to determine if any beep codes exist. Refer to the last
page 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 1MB 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.
