1.1 HARDWARE ENGINEERING SPECIFICATION
1.1.1 General Description
This document describes the engineering specification for 7521 portable notebook computer system.
1.1.2 System Overview
The 7521 model motherboard will accept Intel Pentium III and Celeron processor with FC-PGA packaged. Which will
supports the different levels of Pentium III CPU with FC-PGA package. Those are Pentium III 600/650/700/750/800 MHz,
and Celeron 600/633/667/700/733 MHz .
This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which have standard
hardware peripheral interface and support Intel Pentium III with FC-PGA package. 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 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 functions.
The memory subsystem supports 64MB on board SDRAM, one 144pin DIMM socket for upgrading up to 192 MB of
DRAM using SDRAM DIMM module.
The SiS 630 integrates the north bridge chip, super south bridge and the real 128-bit 3D graphics accelerator all into one
single chip. It provides 10/100M Fast Ethernet, 3D Positional Audio, Advance H/W DVD playback and 2D/3D graphics
engine.
