1. Hardware Engineering Specification
1.1 Introduction
The E-Note P4N266A model motherboard would support the Desktop P4 processor (Northwood) at 2.0/2.2 GHz
and the Celeron low-profile, lidless FC-PGA2 (Flip-chip Pin Grid Array)package on socket 478.
This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which has
standard hardware peripheral interface and support Intel mobile Pentium 4-M and Desktop Pentium 4 family. The
power management complies with Advanced Configuration and Power Interface (ACPI) 1.0b. System also provides
icon LEDs to display system status, such as AC Power / Battery Power indicator and Battery charging status,
CDROM, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK. It also equipped with 4 USB2.0 ports and 1 swap
module (Floppy or card reader or second HDD), one IEEE1394, one PC Card slots, LAN 10/100TX, MDC modem
and AC97 3D stereo audio functions.
The memory subsystem supports two 184pin DIMM socket for upgrading up to 1GB of DDR-SDRAM with
512Mbit DDR-SDRAM technology using PC-100 DDR-SDAM SODIMM modules with SPD. The DDR-SDRAM
controller supports standard PC2100 and PC1600 Synchronous DDR-SDRAM (Double-data-rate SDRAM) .
The VIA VT8703 /P4N266 /Twister-P4 (Apollo ProSavage DDR P4N266) North Bridge Chipset integrated with
S3 Savage4 graphics accelerator and S3’s flat panel interface into a single 664 BGA package. The Twister-P4 brings
mainstream graphics performance to the Value PC with leading-edge 2D, 3D and DVD video acceleration into a
cost effective package.
The Twister-P4 SMA(share memory architecture) system controller also provides superior performance between
the CPU, DRAM, and PCI bus with pipelined, burst, and concurrent operation.
