2. FEATURES 2.1 The ASUS A7M266-D The ASUS A7M266-D motherboard is carefully designed for the value-conscious PC user who needs an entry-level server with the most advanced features processed by the fastest available processors. 2.1.1 Core Specifications ™ • Dual AMD Athlon MP Processor Support: Features the latest CPU, 1.6 GHz...
Three power Connectors: Standard ATX power supply: +5V/3.3V-180W; the power supply must put out at least 1 Amp on the +5V standby lead (+5VSB); ATX 12V/15 Amp power; and one auxillary power connector. ASUS A7M266-D User’s Manual ™ MP processors.
• PCI USB2 Card: A 4-port USB PCI card is bundled with the A7M266-D. • Concurrent PCI: Multiple PCI transfers are now harmonized from the PCI master bus to the memory and processor.
• Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection. • Easy Connectivity and System Information Access: Supports an optional ASUS iPanel, an easy-to-access box with system diagnostic display area, sys- tem status LEDs, USB ports, and hot keys.
