2.1The ASUS A7A266-E

The ASUS A7A266-E motherboard is carefully designed for the value-conscious PC user who wants advanced features processed by the fastest processors.

2.1.1 Core Specifications

•

AMD® Athlon™ / Duron™ Processor Support: Supports AMD’s new socket-

 

A Palomino™ / Thunderbird™ processor cores.

•

North Bridge System Chipset: ALi M1647™ chipset with AGP/PCI/Memory

 

controller supports a 133/100MHz Front Side Bus (FSB), supports DDR SDRAM

 

DIMM, complies with AGP 2.0 specifications for 4X, 2X and 1X AGP modes

 

and PCI 2.2. bus interface. It is optimized to deliver enhanced AMD Athlon™

 

processor system performance.

•

South Bridge System PCIset: ALi M1535D+™ PCIset with PCI Super-I/O In-

 

tegrated Peripheral Controller (PSIPC) with support for UltraDMA/100, which

 

allows burst mode data transfer rates of up to 100MB/sec; AC97 audio; USB

 

controller with root hub and four function ports.

•PC2100 / PC1600 DDR and PC133 SDR SDRAM Support: Equipped with two Double Data Rate Dual Inline Memory Module (DDR DIMM) sockets to support up to 2GB of DDR SDRAM and three SDR DIMM sockets to support up to 3GB of SDR SDRAM. DDR SDRAM is the newest memory standard with the highest bandwidth and lowest latency currently available and dramatically improves the memory system’s ability to service, among others, high multimedia requirements. (Caution: Do not use DDR & SDRAM modules simultaneously.)

•JumperFree™ Mode: Gives processor settings and easy overclocking of

frequency and Vcore voltage all through BIOS setup when JumperFree™ mode is enabled. Easy-to-use DIP switches instead of jumpers are included to allow manual adjustment of the processor’s external frequency. CPU external (FSB) frequency settings may be set in 1MHz-increments or reduction.

•Super Multi-I/O:Provides two high-speed UART compatible serial ports and one parallel port with EPP and ECP capabilities.

•High-Speed Data Transfer Interface: UltraDMA/133 increases the data trans- fer rate to 133MB/s. UltraDMA/133 is backward compatible with both DMA/ 66 and DMA/33 with existing DMA devices and systems. (UltraDMA133/100/ 66 requires a 40-pin80-conductor cable to be enabled.).

•Smart BIOS: 2Mb firmware provides Vcore and CPU/SDRAM frequency ad- justments, boot block write protection, and HD/SCSI/MO/ZIP/CD/Floppy boot selection.

•One Touch Management: Supports an optional ASUS iPanel, an easy to access box with system information LED display, front I/O ports, and space reserved for a hard disk drive. With an ASUS iPanel, you can monitor your computer system’s vital components.
