1-3-4 FIRST 64 ODD/EVEN LOGIC FAILURE, 1-4-1 ADDRESS LINE FAILURE 64K OF RAM
A failure of address or logic chips on the motherboard, which will have to be replaced. Return to main menu.

1-3-3 FIRST 64K RAM CHIP OR DATA LINE FAILURE, MULTI-BIT
For some reason, the first 64k of RAM is not responding to the CPU. The memory chips may be bad; you can try switching the high and low memory on you motherboard to see if the problem goes away. In any machine now a days the first bank of memory contains the first 64k (or the first 256k is the computer is using 256k chips and so on and so forth), so switching the first and second banks(or the third or fourth banks) may solve the problem. Read you PC's instruction manual to find out which is the first bank on your particular motherboard. A motherboard can also cause this problem. If the memory chips all test good, you will have to replace the motherboard itself. Return to the main menu.

1-3-1 RAM REFRESH VERIFICATION FAILURE
The timer chip told the DMA chip to go into RAM and refresh the memory. The DMA chip did this, but the refresh process failed. The possible causes of this malfunction includes;(1) bad memory chip (2)a bad DMA chip, or (3) bad memory addressing chips on the motherboard. Turn off the computer, remove all the memory chips, and test them. Replace any bad chips and retest the computer. Since the DMA chip and the memory address logic chipa are almost always soldered to the motherboard, you will almost certainly have to replace the motherboard. Return to the main menu.

1-2-1 PROGRAMMABLE INTERVAL TIMER FAILURE
There is a bad chip on the motherboard, and the motherboard will have to be replaced. Return to the main menu.
DMA INITIALIZATION 7 PAGE REGISTER WRITE/READ FAILURE
The DMA chip is probably bad. Since this chip is usually permanently soldered into the motherboard, you'll likely to have to replace the whole motherboard. There is a remote possibility that a bad expansion card is grabbing hold of one of the DMA lines and not letting go; you could try removing all cards except for the video card and seeing if the error persist. If it does not continue with the other cards to try to determine the very rare culprit. Return to the main menu.

1-1-3 CMOS WRITE/READ FAILURE
The computer is unable to read the configuration that should be stored in CMOS. If the error persist, replace the motherboard. Return to the main menu.

ELEVEN BEEPS: CACHE MEMORY BAD--DO NOT ENABLE CACHE
This is an indicator that the memory test has failed and has been disabled. On many AMI systems , you could press <+> to enable cache memory, but AMI recommends you do not do so. Instead, try reseating the cache memory on the motherboard and retesting, if the error persist, replace the cache memory. Return to the main menu.

TEN BEEPS: CMOS SHUTDOWN REGISTER READ/WRITE ERROR
When the AT or later CPU chip boots up it transfer into protected mode, then transfers back to real mode (the mode it will use to run DOS). The chip has to reboot to transfer to real mode. Before it reboots, the CPU post a note to itself in CMOS RAM saying "I've just booted. I'm trying to get to real mode to do some work. Don't send me back into protected mode to initialize everything--I've just done that." The likely problem is that CMOS shutdown register on the computer is broken and the CMOS memory and associates chips will have to be replaced; it may be more cost-efficient to replace the motherboard itself.

NINE BEEPS: ROM BIOS CHECKSUM ERROR
EIGHT BEEPS: DISPLAY MEMORY READ/WRITE ERROR

SIX BEEPS: 8042 KEYBOARD CONTROLLER/GATE A20 FAILURE
This error, like phoenix 4-2-3, can be caused either by keyboard problems or a bad problems or a bad motherboard. A rare handful of keyboards have a fuse; check to see if it needs replacement or resetting. Try a different know-good keyboard to see if it solves the problem. If the keyboard seems okay, AMI recommends reseating the keyboard crontroller chips if it is not solvdered to the motherboard. If it still beeps replace the keyboard controller if possible.

FIVE BEEPS: PROCESSOR FAILURE
The CPU chip appears dead, turn off the computer, reset the memory chips, and then retest. If the error continues you can consider replacing the CPU, although that may not be cost efficient-- it may make more sense to replace the motherboard, if you transplant a CPU from another machine, it should ideally be the same speed as your old chip. CPUs takes eight years before dying out.

FOUR BEEPS: SYSTEM TIMER NOT OPERATIONAL
This code may indicate a malfunctioning timer 1, or failure in the first 64k of RAM memory. Turn off the computer, reset any loose chips and retest. If the beep error persists, you can try testing the motherboard with known-good memory from a compatible computer. Replace the first 64k of memory (the single row of chips in a XT clone, two row chips in a 256-based computer, and from one to four rows of chips in a 386 or 486 computer). If you still receive the four-beep error, replaced the motherboard.

THREE BEEPS: BASE 64K MEMORY FAILURE
This error can be cause by bad memory chips or by a bad motherboard. Try resetting the memory chips or the SIMMs or DDRs memory strips. If that doesn't work, follow the directions for phoenix error 1-3-3 of Step 5
TWO BEEPS: PARITY ERROR/PARITY CIRCUIT FAILURE
Many XT and some AT-class computers beep once or twice when booting up normally. If your computer shows standard information on the screen, you do not have a problem. If there is anything wrong, the computer will display a screen error message. If there is no video, check first your computer is turned on and plugged properly. The double beep may be to tell you of parity error in the first 64k of memory. (this is the same as the phoenix BIOS error 1-4-2 describe on Step 5). If your lucky, a memory chip has simply worked itself loose on the motherboard, Reset the chips or the SIMMs or DDRs memory strips; if that doesn't worked, follow the directions for phoenix 1-3-3 of Step 5.

ONE BEEP: DRAM REFRESH FAILURE
Many XT and some AT-class computers beep once or twice when booting up normally. If your computer shows standard information on the screen, you do not have a problem; if there is anything wrong the computer will display a scree error message. If you have no video display, check the simple things first, Is the video monitor plugged in and turned on? Did the video cable from the monitor to computer become disconnected? This single beep tells you there is fault memory refresh circuitry on your motherboard. the timer chip told the DMA chip to go into RAM and refresh the memory. The DMA chip did this, but the refresh process failed. The possible causes of this malfunction are (1) bad memory chips, (2) a bad DMA chip, (3) bad memory addressing chips on the motherboard. Turn off the computer. Reset the memory chip or the SIMMs or DDRs, then retest the computer. Since the DMA chip is almost always soldered to the motherboard--as are the memory address logic chips--any problems with these chips almost always requires the replacement of the motherboard.

MY OJT AT THE OSG 2007
The times I had here is among these moments, when I could say truly the best of days, their friendships and respect will never surpass anything else, so times like this is why life is better. But whether the reason I had fun with colleagues and friends. I could have considered staying but there was something else is missing, and knowing me I won't be able to live with myself if I'd stayed. So packing up without looking back I went looking for the future but leaving behind fond memories with friends. I will miss the Parties and the kakalogan, the kantahan and the smiles of people I respect and admire. But most of all I will miss that day when we won the presentation we made for Solicitor General Nachura as a farewell party who was promoted to Associate Justice of the Supreme Court. It's been more than a year now, by now the Office had probably move to a bigger spot because last time I was there the OSG has already prospecting for the new office which was headed by Mr. Sabino, Chief Admin Officer.
