Just read the UEFI article at: http://www.tomshardware.com/reviews/intel-uefi-firmware.... Have a windows 7 64bit notebook with American Megatrends Inc. AMI Aptio setup utility ver. 1.28.1119 copyrighted in 2008. . Asus has not responded to the specific question about documentation oh the UEFI features and operation. I see a command line when the UEFI option is enabled. I can find no documentation for the utility in the manual, the asus site or american megatrends. Seeking guidance on how one familiarizes themselves with the utility.
