1.3 Unique Features
ASRock Rack Instant Flash is a BIOS ash utility embedded in Flash ROM. is con-
venient BIOS update tool allows you to update system BIOS without entering operat-
ing systems rst like MS-DOS or Windows®. With this utility, you can press the <F6>
key during the POST or the <F2> key to enter into the BIOS setup menu to access
ASRock Rack Instant Flash. Just launch this tool and save the new BIOS le to your
USB ash drive, oppy disk or hard drive, then you can update your BIOS only in a
few clicks without preparing an additional oppy diskette or other complicated ash
utility. Please be noted that the USB ash drive or hard drive must use FAT32/16/12
le system.
