In case of POST error(s) that are listed as Major, the BIOS enters the error manager and waits
for the user to press an appropriate key before booting the operating system or entering the
BIOS Setup.
The user can override this option by setting the POST Error Pause option as disabled on the
BIOS setup Main screen. If this option is disabled, the system boots the operating system
without user intervention. The default is disabled.
