Processor 1 internal error

Processor 2 internal error

Defective microprocessor or system board

(reported by the NMI handler).



Replace the specified microprocessor. See

"Microprocessors." If the problem persists, replace the

system board. See "System Board."

Processor 1 is a 533-MHz system bus processor

Processor 2 is a 533-MHz system bus processor

Two 533-MHz microprocessors are

installed. This system supports only

Intel®Xeon™400-MHz front-side-bus

processors.

Reboot the system. If you receive beep code 4-4-3

(processor frequency mismatch), replace both processors

with Intel Xeon 400-MHz front-side-bus processors. See

"Microprocessors."

If a beep code does not occur at system boot, turn off the

system, install the NVRAM_CLR jumper, and reboot the

system. See Figure5-2 for jumper location.

Processor bus error

PCI bus error

IMB bus error

Defective system board (reported by the

NMI handler).

Replace the system board. See "System Board."

Processor x is not a 533-MHz system bus

processor

This system bus speed is not supported on this

system board

This system supports only Intel Xeon 533-

MHz front-side bus (system bus)

processors.

Reboot the system. If you receive beep code 4-4-3

(processor frequency mismatch), replace processor x with

a supported processor. See "Microprocessors."

If a beep code does not occur at system boot, turn off the

system, install the NVRAM_CLR jumper, and reboot the

system. See Figure5-2 for jumper location.

Read fault

Requested sector not found

Faulty diskette, diskette-drive subsystem,

or hard-drive subsystem.

Replace the diskette. Reseat all drives and reboot the

system. If the message reappears, replace the diskette

drive. See "Installing a Diskette Drive." If the problem

persists, replace the system board. See "System Board."

Reset failed

Improperly connected diskette/tape drive,

hard drive, or power cable.

Check the drive and cable connections, and reset the

system again.

ROM bad checksum = address

Expansion card improperly installed or

faulty.

Reinstall the expansion card. See "Expansion Cards." If

the problem persists, replace the expansion card.

Sector not found

Seek error

Seek operation failed

Defective sectors on diskette or hard

drive.

Faulty diskette, diskette-drive subsystem,

or hard-drive subsystem.

Replace the diskette, or reseat all drives and reboot the

system. See "Installing a Diskette Drive" or "Internal SCSI

Hard Drives." If the message reappears, replace the drive

(s). If the problem persists, replace the system board.

See "System Board."

Shutdown failure

Defective system board.

Replace the system board. See "System Board."

System backplane error

Improperly attached or missing SCSI

backplane.

Reseat the SCSI backplane. See "SCSI Backplane Board."

System halted! Must power down.

Wrong password entered too many

times.

Reboot the system and enter the correct password. If the

problem persists, see "Disabling a Forgotten Password."

System parity error

Defective expansion card(s) or improperly

seated or faulty memory modules

(reported by the NMI handler).

Replace the expansion cards one at a time until the error

is corrected. See "Expansion Cards."

Remove and reseat the memory modules. See "Memory."

If the problem persists, replace the memory modules. If

the problem persists, replace the system board. See

"System Board."

The following memory DIMMs are unsupported:

DIMM_xx.

This system only supports 266 MHz DIMMs.

One or more of the installed DIMMs has a

frequency less than 266 MHz. System

memorymustberatedfor266MHz.

Replace lower-speed DIMM(s) with modules rated for 266-

MHz operation. See "Memory."

This processor system bus speed is unknown.

System halted!

The installed microprocessor is not

supported by the system.

Reboot the system. If you receive beep code 4-4-3

(processor frequency mismatch), replace the installed

microprocessor(s) with microprocessor(s) supported by

your system. See "Microprocessors."

If a beep code does not occur at system boot, turn off the

system, install the NVRAM_CLR jumper, and reboot the

system. See Figure5-2 for jumper location.

This system only supports 400-MHz system bus

speed.

System halted!

Two 533-MHz microprocessors are

installed. This system supports only Intel

Xeon 400-MHz front-side-bus processors.

Reboot the system. If you receive beep code 4-4-3

(processor frequency mismatch), replace both processors

with Intel Xeon 400-MHz front-side-bus processors. See

"Microprocessors."

If a beep code does not occur at system boot, turn off the

system, install the NVRAM_CLR jumper, and reboot the

system. See Figure5-2 for jumper location.

Time-of-day clock stopped

Defective battery or faulty chip (defective

system board).

Replace the system battery. See "System Battery." If the

problem persists, replace the system board. See "System

Board."

Time-of-day not set - please run SETUP program

Incorrect Time or Date settings or

defective system battery.

Check the Time and Date settings. See "Using the

System Setup Program." If the problem persists, replace

the system battery. See "System Battery." If the problem

persists, replace the system board. See "System Board."

Timer chip counter 2 failed

Defective system board.

Replace the system board. See "System Board."

Unsupported CPU combination

Microprocessor combination is not

supported by the system.

Install a supported microprocessor combination. See

"Microprocessors."

Unsupported CPU stepping detected.

Microprocessor is not supported by the

system.

Install the correct version of the microprocessor in the

specified microprocessor socket. See "Microprocessors."

Utility partition not available

<F10> key was pressed during POST, but

Create a utility partition on the boot hard drive. See

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 50 51
