You may try again to enter the correct password. If you enter the
password incorrectly three times, the system responds in one of two
different ways, depending on the value specified in the Password
Checking option on the Advanced Setup screen:
1) If the Password Checking option is set to Setup, the system
does not let you enter Setup, but does continue the booting
process. You must reboot the system manually to retry enter-
ing the password.
2) If the Password Checking option is set to Always, the system
locks and you must reboot. After rebooting, you will be re-
quested to enter the password.
Once the password has been entered correctly, you are allowed to
continue.
BIOS Errors
If an error is encountered during the diagnostic checks performed
when the system is powered on, the error is reported in one of two
different ways:
1) If the error occurs before the display device is initialized, a
series of beeps is transmitted.
2) If the error occurs after the display device is initialized, the
screen displays the error message. In the case of a non-fatal
error, a prompt to press the <F1> key may also appear on the
screen.
Explanations of the beep codes and BIOS error messages may be
found in Appendix A - BIOS Messages.
As the POST routines are performed, test codes are presented on
Port 80H. These codes may be helpful as a diagnostic tool and are
listed in Appendix A - BIOS Messages.
