V. DESKTOP MANAGEMENT Desktop Management Interface (DMI) Introducing the ASUS DMI Configuration Utility This motherboard supports DMI within the BIOS level and provides a DMI Con- figuration Utility to maintain the Management Information Format Database (MIFD). DMI is able to auto-detect and record information pertinent to a computer’s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size.
V. DESKTOP MANAGEMENT Using the ASUS DMI Configuration Utility Edit DMI (or delete) Use the (left-right) cursors to move the top menu items and the (up-down) cursor to move between the left hand menu items. The bottom of the screen will show the available keys for each screen.
