1. Engineer hardware Specification
1.1 Introduce
The 8640 motherboard would support the Intel D/T or Mobile Pentium 4 (Willamette) / Northwood & Celeron in
mFC-PGA2 packaged, which will supports the different speed up to 1.9G/ 2G/2.2G/2.3G./3.2G above.
This system is based on PCI architecture, which have standard hardware peripheral interface. The power
management complies with Advanced Configuration and Power Interface (ACPI) 1.0b. It also provides easy
configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing F2 at
system start up or warm reset. System also provides icon LEDs to display system status, such as Power indicator,
Battery, HDD, CD-ROM,USBFDD,NUM LOCK, CAP LOCK, SCROLL LOCK status. It also equipped 4 USB
ports.
The memory subsystem supports 1024MB DDR SDRAM ,and two JEDEC-standard 200-pin, small-outline, dual
in-line memory module (SODIMM) , support PC2100.
SiS651 IGUI Host Memory Controller integrates a high performance host interface for Intel Pentium 4 processor,
a high performance 2D/3D Graphic Engine, a high performance memory controller, an AGP 4X interface, and
SiS MuTIOL? Technology connecting w/ SiS962 MuTIOL? Media IO.
The SiS962 MuTIOL? Media I/O integrates the Audio Controller with AC 97 Interface, the Ethernet MAC, the
Dual Universal Serial Bus Host Controllers, the IDE Master/Slave controllers, and the MuTIOL? Connect to PCI
bridge. The PCI to LPC bridge, I/O Advanced Programmable Interrupt Controller, legacy system I/O, I/O
Advanced Programmable Interrupt Controller and legacy power management functionalities are also integrated.
The SiS962 also incorporates a universal interface supporting the asynchronous inputs/outputs of the X86
compatible microprocessors like P4.
