BIOS Features

For the P8Z77-I Deluxe, ASUS used the the latest version of its customized UEFI (Unified Extensible Firmware Interface) BIOS. The UEFI BIOS offers full keyboard and mouse support while in the BIOS pages. By default, the user sees the EZ mode screen when entering the BIOS with the Advanced mode screens accessible via the Exit/Advanced Mode button at the upper-right corner of the screen. Advanced mode screens can be set to be the default user interface via the BIOS Boot menu as well.

There is a lot to like about ASUS’ UEFI BIOS implementation. The company has one of the best implementations of UEFI on the market currently. The BIOS is very responsive to both keyboard and mouse input with no lag or questionable click-space evident anywhere. It is intuitively laid out so that both novice and advanced BIOS users alike can easily find what they are looking for quickly with the EZ Mode screen laying out everything in a highly readable format. Meanwhile the Advanced Mode's tabbed  interface is laid out as you would expect from a traditional (read old-school) BIOS. ASUS also gives you the ability to taken screen captures from within the BIOS by pressing the F12 key with those screen-caps saved in a 1024×768 bitmap format to an attached USB device. From the Tools menu, ASUS houses its collection of BIOS-related tools and applets, ranging from an in-BIOS updater (EZ Flash2) to its full BIOS profile load and save utility.
