EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool & update BIOS from a USB (Universal Serial Bus) flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing an additional floppy diskette or using an OS-based flash utility. The ASUS Crash Free BIOS 3 allows users to restore corrupted BIOS data from a USB (Universal Serial Bus) flash disk containing the BIOS file. This utility saves users the cost & hassle of buying a replacement BIOS chip. The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192 K Hz/24-bit audio output & jack-detect feature that automatically detects & identifies what types of peripherals are plugged into the audio I/O jacks & notifies users of inappropriate connection, which means there will be no more confusion of Line-in, Line-out, & Mic jacks.
