Cause
The keyboard controller may be mal-
functioning, or one or more SIMMs
or DIMMs may be loose.
POST has queried the EIDE drive for
status information. The drive has
returned a parameter from the call
that indicates it has detected possible
error conditions for its operating
specifications.
Action
Run the RAM Test Group and the Keyboard Con-
troller Test in the Dell Diagnostics. See Chapter 4,
"Running the Dell Diagnostics."
Once your computer finishes booting, immediately
back up your data and replace your hard-disk
drive. Restore the data to the replaced drive.
If a replacement drive is not immediately available
and the drive is not the only bootable drive, enter
the System Setup program and change the appro-
priate drive setting to None. Remove the drive
from the system. This should be done only after
you have backed up the data.
