| Intel "Zappa" Motherboard |
Errors can occur during POST (Power On Self Test) which is performed every time the system is powered on. Fatal errors, which prevent the system to continue the boot process, are communicated through a series of audible beeps. Other errors are displayed in the following format:
ERROR Message Line 1
ERROR Message Line 2
For most displayed error messages, there is only one message. If a second message appears, it is "RUN SETUP". If this message occurs, press <F1> to run AMIBIOS Setup.
BEEP CODES
| The memory refresh circuitry on the baseboard is faulty. | ||
| Parity is not supported on this product, will not occur. | ||
| Memory failure in the first 64 KB. | ||
| Memory failure in the first 64 KB of memory, or Timer 1 on the baseboard is not functioning. | ||
| The CPU on the baseboard generated an error. | ||
| The keyboard controller (8042) may be bad. The BIOS cannot switch to protected mode. | ||
| The CPU generated an exception interrupt. | ||
| The system video adapter is either missing or its memory is faulty. This is not a fatal error. | ||
| ROM checksum value does not match the value encoded in BIOS. | ||
| The shutdown register for CMOS RAM failed. | ||
| The external cache is faulty. |
ERROR MESSAGES
| Gate A20 on the keyboard controller (8042) is not working. Replace the 8042. | |
| Error in the address decoding circuitry on the baseboard. | |
| Cache memory is defective. Replace it. | |
| Most AT systems include two timers. There is an error in timer 2. | |
| CMOS RAM is powered by a battery. The battery power is low. Replace the battery. | |
| After CMOS RAM values are saved, a checksum value is generated for error checking. The previous value is different from the current value. Run AMIBIOS Setup. | |
| The values stored in CMOS RAM are either corrupt or nonexistent. Run Setup. | |
| The video type in CMOS RAM does not match the type detected by the BIOS. Run AMIBIOS Setup. | |
| The amount of memory on the baseboard is different than the amount in CMOS RAM. Run AMIBIOS Setup. | |
| Run Standard CMOS Setup to set the date and time in CMOS RAM. | |
| The boot disk in floppy drive A: is corrupt. It cannot be used to boot the system. Use another boot disk and follow the screen instructions. | |
| Some systems require a video switch on the baseboard be set to either color or monochrome. Turn the system off, set the switch, then power on. | |
| Error in the DMA controller. | |
| Error in the first DMA channel. | |
| Error in the second DMA channel. |
ERROR MESSAGES (CONT.)
| The BIOS cannot communicate with the floppy disk drive controller. Check all appropriate connections after the system is powered down. | |
| The BIOS cannot communicate with the hard disk drive controller. Check all appropriate connections after the system is powered down. | |
| Interrupt channel 1 failed POST. | |
| Interrupt channel 2 failed POST. | |
| The BIOS can read the disk in floppy drive A:, but cannot boot the system. Use another boot disk. | |
| The keyboard lock on the system is engaged. The system must be unlocked to continue. | |
| There is a timing problem with the keyboard. Set the Keyboard option in Standard CMOS Setup to Not Installed to skip the keyboard POST routines. | |
| There is an error in the keyboard connector. | |
| Parity error in memory installed in an expansion slot. The format is:
OFF BOARD PARITY ERROR ADDR (HEX) = (XXXX) XXXX is the hex address where the error occurred. | |
| Parity is not supported on this product, this error will not occur. | |
| Parity error in system memory at an unknown address. |
PLUG AND PLAY ERROR MESSAGES
| The serial ID checksum of a Plug and Play card was invalid. | |
| The floppy disk controller has requested a resource that is already in use. | |
| The ESCD data was reinitialized because of an NVRAM checksum error. Try rerunning the ICU. | |
| The "Clear CMOS" switch has been moved to the ON position and CMOS RAM has been cleared. | |
| Invalid entry in the ESCD area. | |
| The parallel port has requested a resource that is already in use. | |
| This message is displayed when more than 15 PCI conflict errors are detected. No additional PCI errors can be logged. | |
| Two devices requested the same resource, resulting in a conflict. | |
| Two devices requested the same resource, resulting in a conflict. | |
| Two devices requested the same resource, resulting in a conflict. | |
| The designated primary boot device (hard disk drive, diskette drive, etc.) could not be found. | |
| The primary IDE controller has requested a resource that is already in use. | |
| The designated primary input device (keyboard, mouse, or other, if input is redirected) could not be found. | |
| The secondary IDE controller has requested a resource that is already in use. | |
| Serial port 1 has requested a resource that is already in use. | |
| Serial port 2 has requested a resource that is already in use. | |
| A non-Plug and Play ISA card has requested a resource that is already in use. | |
| A non Plug and Play system resource has requested a resource that is already in use. |
ISA NMI MESSAGES
| Memory failed. If the memory location can be determined, it is displayed as xxxxx. If not, the message is Memory Parity Error ????. | |
| An expansion card failed. If the address can be determined, it is displayed as xxxxx. If not, the message is I/O Card Parity Error ????. | |
| A device has driven the bus signal for more than 7.8 microseconds. |
