2.1.1 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.)
• 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
optional PCI Fast Ethernet card.
• Wake-On-Ring Connector: Supports Wake-On-Ring activity through a PCI
modem card that supports a Wake-On-Ring connector.
