Whenever you start up your system, the CPU card runs a series of
programs to test and initialize board hardware. If the routines
encounter an error in during the tests, you will either hear a few
short beeps or see an error message on the screen. There are two
kinds of errors: fatal and non-fatal. The system can usually
continue the boot up sequence with non-fatal errors. Non-fatal
error messages usually appear on the screen along with the
following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the
bootup sequence. The cure for most non-fatal error messages is
simply to run the BIOS SETUP program, discussed in Chapter 5.
If the routines encounter a fatal error, they will stop the tests and
output a message indicating which test failed. If the fatal error
comes before the screen device initializes, the card will indicate
the error code through a series of beeps.
You can also determine the number of the test that failed by
reading the LED indicators on the top of the PCA-6143P board.
Please make a note of any BIOS error codes before you contact
Advantech for technical support.
Beep codes indicate fatal errors through a series of audible tones
output through the card's buzzer or a speaker. The number of
beeps indicates the error, as shown in the following table:
Beeps Meaning
1 Refresh failure – The card's memory refresh circuitry is faulty.
2 Parity error – A parity error was detected in the base memory
(the first block of 64 KB) of the system.
3 Base 64 KB memory failure – A memory failure occurred within
the first 64 KB of system memory.
4 Timer not operational – Timer #1 on the card has generated an
error.
