Message Causes Corrective Actions
Address mark not found Faulty diskette/CD drive subsystem or
hard-drive subsystem (defective system
board). Replace the system board. See " System Board ."
Amount of available memory limited to 256 MB! OS Install Mode is enabled in the System
Setup program. Disable the OS Install Mode. See " Using the System
Setup Program ."
Alert! One or more of the memory DIMMs are out
of rev.
One or more of the installed DIMMs are
not supported by the system. DIMMs
must be registered DDR SDRAM rated for
266-MHz operation. Ensure that all installed memory meets the system
specifications. See "
Memory ."
Alert! Redundant memory disabled! Memory
configuration does not support redundant memory.
One memory bank is not populated, or
memory banks are different sizes. To
support redundant memory, both banks
must be populated, and all four DIMMs
must be the same size. Install identical DIMMs in all four memory banks. See
"
Memory ."
Alert! Unsupported memory, incomplete sets, or
unmatched sets.
The following memory DIMM(s) have been
disabled: DIMM_xx
DIMMs are installed in a mismatched pair,
or one memory slot in a bank is empty.
Memory must be installed in matched
pairs. In a mismatched memory bank,
neither DIMM is used. Ensure that memory is installed in matched pairs. See
"
Memory ."
Auxiliary device failure Mouse or keyboard cable connector loose
or improperly connected; defective mouse
or keyboard. Check the mouse and keyboard cable connections. See
"
External Visual Inspection ."

are installed. Install a correct version of the microprocessor so that
both microprocessors have the same level 2 cache size.
See "
Microprocessors ."
Data error Faulty diskette, diskette drive, or hard
drive. Replace the diskette. Reseat all drives, check cable
connections, and reboot the system. If the problem
persists, replace the diskette drive or hard drive. See
"
