2.1 The ASUS A7A133

The ASUS A7A133 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 standard

PC133/100 SDRAM DIMM, and 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.

• PC133 SDRAM Support: Equipped with three SDR DIMMs supporting PC133/

PC100 compliant (8, 16, 32, 64, 128, 256 or 512 MB) modules up to 3GB of

SDRAM.

• 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. CPU external (FSB)

frequency settings may be set in 1MHz-increments or reduction.

• High-Speed Data Transfer Interface: UltraDMA/100 increases the data trans-

fer rate to 100MB/s. UltraDMA/100 is backward compatible with both DMA/

66 and DMA/33 with existing DMA devices and systems. (UltraDMA100/66

requires a 40-pin 80-conductor cable to be enabled.)

• Super Multi-I/O: Provides two high-speed UART compatible serial ports and

one parallel port with EPP and ECP capabilities.

• 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.
