6.42 "POST Error Pause" Option

In case of POST error(s), which occur during system boot-up, BIOS will stop and wait for the
user to press an appropriate key before booting the O/S or entering BIOS setup. The user can
override this option by setting "POST Error Pause" to "disabled" on the BIOS Setup Server
menu page. If the "POST Error Pause" option is set to "disabled", the system will boot the
operating system without user-intervention. Option default value is set to "enabled".
