*Stuck Key
BIOS discovered a stuck key and displays the scan code for the stuck key. You may have to replace
your keyboard but may be able to use an external keyboard until then. Contact your support
representative.
*Monitor type does not match CMOS – Run SETUP
Monitor type not correctly identified in Setup. This error probably means your BIOS is corrupted, run
the setup utility and set all settings to the default conditions. If you still get this error, contact your
support representative.
*Operating system not found
Operating system cannot be located on either drive A: or drive C: Enter the setup utility and see if both
the fixed disk, and drive A: are properly identified and that the boot sequence is set correctly. Unless
you have changed your installation greatly, the operating system should be on drive C:. If the setup
utility is correctly set, your hard drive may be corrupted.

If it cannot locate the address, it displays ????. This is a potentially data destroying failure. Contact
your support representative.
*Parity Check 2 nnnn

it cannot locate the address, it displays ????. This is a potentially data-destroying failure. Contact
