Cause
A cable or connector
may be loose, or the
keyboard controller may
be faulty.
The EISA jumper may
have been accidentally
installed.
The EISA data in
NVRAM does not
match the installed
EISA expansion cards.
The microprocessor-
speed jumper plug may
be absent or installed on
the wrong pins.
The BIOS detected a
resource conflict while
configuring a Plug and
Play ISA or PCI expan-
sion card.
A chip on the system
board may be mal-
functioning.
DIMM memory may
have been added or
removed, or one or more
DIMMs may be improp-
erly seated or faulty.

Action
Check the keyboard cable and connector for proper connec-
tion. If the problem persists, run the Keyboard Test Group in
the system diagnostics to determine whether the keyboard or
keyboard controller is faulty. See Chapter 5, "Running the
System Diagnostics."
Remove the EISA jumper, reboot the system, and restore the
EISA configuration parameters. See Chapter 5, "Using the
EISA Configuration Utility," in the User's Guide.
Verify that any installed EISA expansion cards are properly
seated, and then run the EISA Configuration Utility to verify
that the configuration parameters are correct. See Chapter 5,
"Using the EISA Configuration Utility," in the User's Guide.
Check the microprocessor speed jumpers. See Table C-1.
See "Resolving Resource Conflicts" in Chapter 5 in the User's
Guide.
Run the System Set Test Group. See Chapter 5, "Running the
System Diagnostics." A faulty chip on the system board usu-
ally requires that you replace the system board.
Remove and reseat the DIMMs. See "Installing DIMMs" and
"Removing DIMMs" in Chapter 8. If the problem persists, run
the RAM Test Group in the system diagnostics. See Chapter 5,
"Running the System Diagnostics."
Replace the microprocessor with a correct version of the Pen-
tium Pro microprocessor from Dell. See "Upgrading the
Microprocessor or Installing a Secondary Microprocessor" in
Chapter 8 for details.
