The ASUS A7M266 motherboard is carefully designed for the value-conscious PC
user who wants advanced features processed by the fastest processors.
2.1.1 Specifications
• AMD Athlon™/Duron™ Processor Support: Supports Socket A-based AMD
Athlon™/Duron™ processors.
• North Bridge System Chipset: AMD-761™ chipset with AGP/PCI/Memory
controller supports a 266MHz 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 with support for 5 PCI masters. It is optimized to
deliver enhanced AMD Athlon™ processor system performance.
• “Super South” South Bridge System PCIset: VIA VT82C686B PCIset with
PCI Super-I/O Integrated 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 SDRAM Support: Equipped with two Double Data
Rate Dual Inline Memory Module (DDR DIMM) sockets to support up to 2GB of
DDR 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.
• Stepless Frequency Selection: Allows CPU external (FSB) frequency settings
to be set in 1MHz-increments or reduction.
• JumperFree™ Mode: Allows processor settings and easy overclocking of fre-
quency 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.
• AGP Pro Slot: Supports AGP/AGP Pro cards for high performance, component
level interconnection targeted at 3D graphical applications supporting 133MHz
4X mode.
• UltraDMA/100 Support: Comes with an onboard PCI Bus Master IDE con-
troller with two connectors that support four IDE devices on two channels. Sup-
ports UltraDMA/100, UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and Bus
Master IDE DMA Mode 2, and Enhanced IDE devices, such as DVD-ROM,
CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
• Wake-On-LAN Connector: Supports Wake-On-LAN activity through an op-
tional ASUS PCI-L101 10/100 Fast Ethernet PCI card (see 7. Appendix).
• Wake-On-Ring Connector: Supports Wake-On-Ring activity through a PCI
modem card that supports a Wake-On-Ring connector.
• USB: Supports up to 4 USB ports, two on the back panel and two midboard, for
more peripheral connectivity options.
