vanced features processed by the fastest CPU.
Specifications:
• Multi-Speed: Supports Intel Pentium® II (233MHz to 450MHz) and CeleronTM
(266MHz and faster) processors.
Intel AGPset: Features Intel’s 440BX AGPset with I/O subsystems and front-side
bus (FSB) platform, which boosts the traditional 66-MHz internal bus speed to 100MHz.
•
• Multi-Cache: Supports processors with Pipelined Burst Level 2 cache.
•
PC100 Memory Support: Equipped with three DIMM sockets to support Intel
PC100-compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 768MB. These
new SDRAMs are necessary to meet the critical enhanced 100MHz bus speed
requirement.
Peripheral Wake Up: Supports modem wake up, keyboard wake up, and LAN
card wake up functions from sleep or soft-off mode.
•
• Chassis Intrusion Detection: Supports chassis-intrusion monitoring through LDCM.
PC Health Monitoring: Provides an easier way to examine and manage system
•
status information such as system voltage, temperature, and fan status through
the provided software.
• AGP Slot: Supports AGP graphics cards for high performance, component level
•
•
•
•
interconnect targeted at 3D graphical display applications.
SB-Link™: Features Creative’s SB-Link™, allowing SB16 compatibility, us-
ing Intel’s PC-PCI DMA and serialized IRQ protocols, to AWE64D or compat-
ible PCI audio cards.
SMBus: Features the System Management Bus interface, which is used to physi-
cally transport commands and information between SMBus devices.
PCI & ISA Expansion Slots: Provides three 32-bit PCI and two 16-bit ISA
slots. One ISA slot is shared with a PCI slot.
Super Multi-I/O: Provides two high-speed UART compatible serial ports and
one parallel port with EPP and ECP capabilities. UART2 can also be directed
from COM2 to the Infrared Module for wireless connections.
• Ultra DMA/33 Bus Master IDE: Comes with an onboard PCI Bus Master IDE
controller with two connectors that support four IDE devices in two channels, sup-
ports UltraDMA/33, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 2, and
supports Enhanced IDE devices, such as Tape Backup, CD-ROM, and LS-120 drives.
• Universal Retention Mechanism: Supports a Pentium® II processor packaged
in a Single Edge Contact Cartridge (SECC/SECC2) or a CeleronTM processor
packaged in a Single Edge Processor Package (SEPP).
• Wake-On-LAN Header: Supports Wake-On-LAN activity with special net-
work cards, such as the ASUS PCI-L101 10/100 Fast Ethernet PCI card.
