1.1.1 General Description

This document describes the engineering specification for 7521 plus portable notebook computer system.

1.1.2 System Overview

The 7521 plus model motherboard will accept Intel Pentium III at FSB 133/100MHz and Celeron at FSB 66MHz processor with FC-PGA packaged. Those are Pentium III 600/650/667/700/733/ 750/800/866 MHz, and Celeron 3/566/600/633/667/700/733/766 MHz.

This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which has standard hardware peripheral interface. The power management complies with Advanced Configuration and Power Interface (ACPI)

1.0.It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing F2 key at system start up or warm reset. System also provides icon LEDs to display system status, such as AC Power indicator, FDD, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK, SUSPEND MODE and battery present, capacity & charging status. It also equipped with LAN, FIR, USB port, 3D stereo audio and TV-OUT functions.

The memory subsystem supports 64MB on board SDRAM, one 144pin SO-DIMM socket for upgrading up to 320MB.
The SiS630S integrates the north bridge chip, super south bridge and the real 128-bit 3D graphics accelerator all into one
single chip. It provides, 3D Positional Audio, Advance H/W DVD playback and 2D/3D graphics engine.
The TI 1225 cardbus controller supports PCMCIA and CARDBUS. The National Semiconductor PC97338 Super I/O
controller integrates the standard PC I/O functions: floppy interface, two FIFO serial ports, one EPP/ECP capable parallel
port, and support for an IrDA 1.1, 1.0 and sharp ASK compatible infrared interface. To provide for the increasing number
of multimedia applications, a CODEC CS4299 is integrated onto the motherboard that support 16-bit stereo, Sound Blaster
Pro, Windows Sound System compatibility, and full-duplex capabilities to meet the demands of interactive multimedia
applications.	3
