•
• North Bridge System Chipset: The Intel® 815EP chipset supports a 66/100/
133 Front Side Bus (FSB), up to 512MB of PC100/PC133 SDRAM, and AGP
4X mode, which can transport twice the amount of data compared to the current
AGP standard.
South Bridge System Chipset: The Intel I/O Controller Hub 2 (ICH2) features
support for UltraDMA/100, which allows burst mode data transfer rates of up to
100MB/sec; two USB controllers for a total of 4 USB ports; and six channel
AC97 CODEC support.
Intel® Accelerated Hub Architecture: Features a dedicated high speed hub
link between the ICH2 and GMCH with a bandwidth of 266MB/sec – twice the
maximum bandwidth of the PCI bus.
PC100/PC133 Memory Support: Equipped with three Dual Inline Memory
Module (DIMM) sockets to support PC100/PC133-compliant SDRAMs (avail-
able in 64, 128, 256, 512MB densities) up to 512MB.
•
•
• AGP Slot: Comes with an Accelerated Graphics Port slot that supports AGP
cards for high performance, component level interconnect targeted at 3D graphical
applications supporting 133MHz 4X mode. Backward compatible to support
AGP 2X.
• UltraDMA33/66/100 Support: Comes with an onboard PCI Bus Master IDE
controller with two connectors that support four IDE devices on two channels.
Supports 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-Up Support: Supports Wake-On-LAN and Wake-On-Ring, Keyboard
Wake-Up, and BIOS Wake-Up.
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.
• Around-the-Clock Intrusion Detection: Chassis intrusion circuitry can log
chassis open events into LDCM. The onboard battery supports detection even
when normal power is removed and through a new design, battery drain is even
lower than the RTC used for keeping time!
