Quiet Boot	Enables or disables the Quiet Boot func-
	tion. When set to Enabled, BIOS setup is in

	tification logo during POST and while
	booting. After booting, the screen displays
	the operating system prompt (such as DOS)

	occurs while booting, the system
	automatically switches to text mode.

	still switch to text mode while booting by

	data from different applications without
	losing track of the data processing status
	of each.
