V. Simple Boot Flag function This function automatically optimizes the behavior and boot performance of the BIOS and operating system, based on the installed operating system and previous boot.

If you are going to use a non-Plug and Play-capable operating system, disable this function so that the BIOS will configure hardware resources.
