MultiVOIP Gatekeeper User Guide
4. Replace the NIC board in question with a verified “good” unit, then repeat the diagnostic
tests.
5. Install the questioned NIC board in another PCI computer and repeat the diagnostic tests on it
there.
Diagnostic Tests
The Gatekeeper operates like any stand-alone PC and can run almost any off-the-shelf diagnostic
program or checkpoint card. These programs are available at any software re-seller and can quickly
help isolate component failures.
Troubleshooting with Error Messages
This section outlines errors that may occur during system operation and likely remedies for these
problems.This section describes error messages and their use in troubleshooting. Since many errors
can be caused by poor cable connections, you should first verify that all cables are connected firmly to
their proper receptacles. If error messages persist after the recommended adjustments have been
made, contact Multi-Tech Systems for maintenance.
Post Beep: The BIOS generates two beeping (audible) error codes.
(1) A single long beep followed by three short beeps indicates that a video error has occurred and
the BIOS cannot initialize the video screen to display any additional information.
(2) A single long beep sounded repeatedly indicates that a DRAM error has occurred.
CMOS Battery Failure: If the CMOS battery is low or dead, it should be replaced. Replacement
requires soldering. If the clock fails, return the SBC to Multi-Tech Systems for repair.
CMOS Checksum Error: This error indicates that the CMOS has been corrupted, possibly by a weak
battery. Reconfigure the CMOS settings, then check to see if this is a continuous problem.
Disk Boot Failure: When you can‘t find the boot device, insert a system disk into Drive A and press <
Enter >. Make sure that the controller and the cables are in their proper positions and that the hard
drive has been formatted correctly. Then reboot the system. Verify the hard drive and floppy drive
selections in the CMOS Setup.
Diskette Drives Or Types Mismatch Error: When the diskette drive type is different from the
settings specified in CMOS (BIOS Setup), run Setup and re-configure the drive.
Error Encountered Initializing Hard Drive: If you cannot initialize the hard drive, check that the
adapter has been installed correctly and that all cables are correctly and firmly attached. Also be sure
the correct hard-drive type has been selected in the BIOS Setup.
Error Initializing Hard Disk Controller: When this error occurs, check to see that the cable
connecting the hard drive to the motherboard is seated properly in its receptacle. Make sure the correct
hard-drive type has been selected in the BIOS Setup. Also, check to see that all of the jumpers in the
hard drive unit have been set correctly.
Floppy Disk Controller Error or No Controller Present: When you cannot find or initialize the
floppy drive controller, please check that the controller settings in the BIOS Setup screen match the
actual controller being used. If no floppy drives are installed in your PC, be sure the Diskette Drive
field of the Setup screen is set to NONE.
Keyboard Error Or No Keyboard Present: When this error message appears, check to see that
your keyboard is attached properly to its receptacle. Make sure JP6 is jumpered for keyboard. Also, be
sure that no keys are being pressed during the booting process. If you are purposely configuring the
system without a keyboard, set the error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. This
will cause the BIOS to ignore the missing keyboard and continue the boot.
Memory Address Error: If the memory address indicates an error, use the specified location and the
memory map for your system to find and replace the bad memory chips.
Memory Verifying Error : It indicates an error verifying a value already written to memory. Try
reseating the memory SIMMs or replace them one at a time.
