Chapter 1: Product introduction
USB 2.0 connectivity
The P4S800-MX rear panel is equipped with four (4) Universal Serial Bus (USB)
ports to connect USB 2.0 devices. A USB header is also available at mid-board to
accommodate a USB module for two (2) additional USB ports. The USB ports and
header comply with USB 2.0 specification that supports up to 480 Mbps connection
speed. This speed advantage over the conventional USB 1.1 (12 Mbps) allows
faster Internet connection, interactive gaming, and simultaneous running of
high-speed peripherals. USB 2.0 is backward compatible with USB 1.1.
See pages 1-17 and 1-20.
ASUS CrashFree BIOS
CrashFree BIOS allows users to restore BIOS  data from a floppy diskette even
when BIOS code and data are corrupted during upgrade or invaded by a virus.
Unlike other competing vendors’ products, ASUS motherboards now enable users
to enjoy this protection feature without the need to pay for an optional ROM.
See page 2-6.
ASUS EZ Flash BIOS   
With the ASUS EZ Flash, you can easily update the system BIOS even before
loading the operating system. No need to use a DOS-based utility or boot from a
floppy disk. See page 2-3.
