Description/Action
The CMOS Date and/or Time are
invalid. This error can be resolved by
readjusting the system time in AMI
BIOS Setup.
The Fan is bad or stop rotation.
Make sure the Fan device is working.
Checksum of CMOS is incorrect.
The computer loads the default
configuration settings. This error
might indicate that CMOS has
become corrupt due to a weak
CMOS battery.
The SATA device configured as
Primary Master could not be found
or initialized. Make sure the hard
drive is correctly installed.
Cannot initialize the keyboard.
Make sure the keyboard is properly
connected to the computer and
that no keys are held pressed during
POST.
To purposely configure the
computer without a keyboard, set
keyboardless operation in Setup to
Enable. The BIOS then ignores the
missing keyboard during POST.
The system has been halted. A reset
or power cycle is required to reboot
the machine. This message appears
after a fatal error has been detected.
The BIOS was unable to find a
suitable boot device.
Make sure the boot drive is properly
connected to the computer.
Make sure you have bootable
media.
