1.Hardware Engineering Specification
1.1 Introduction
This system is based on PCI architecture which have standard hardware peripheral interface. The
power management complies with Advanced Configuration and Power Interface (ACPI) 1.0. 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 Power indicator, LAN, HDD/CDROM, NUM LOCK,CAP LOCK, SCROLL
LOCK, SUSPEND MODE and Battery charging status. It also equipped with Zoom Video capture port,
FIR, 2 USB ports.
The 7321 model motherboard would support the AMD K7 processor with CPGA packaged,socket
A,which will supports the different levels of AMD K7 CPU with CPGA package,Including Athlon
650/700/750/800/900/1000 MHz,and Duron 600/650/700/750/800/900 MHz.
The memory subsystem supports 64MB SDRAM on board and one 144 pin SO-DIMM socket for
upgrading up to maximum 320MB of DRAM using PC-100 or PC-133 SDRAM SO-DIMM module.

The TwisterK integrates VIA’s VT8362 KN133 system controller,S3’s Savage4 2D/3D graphics
accelerator and S3’s flat panel interfaces into a single 552 BGA package. The TwisterK SMA system
controller provides superior performance between the CPU,DRAM and PCI bus with, pipelined,burst
and concurrent operation.
Savage4 graphic accelerator integrated in TwisterK brings mainstream graphics performance with
leading-edge 2D,3D and DVD video acceleration .Also with a new super-pipelined 128-bit engine for
utilizing a single cycle architecture that provides high performance along with superior image
quality.Several new features enhance the 3D architecture,including single-pass multitexturing, full scene
anti-aliasing,anisotropic filtering,and an 8-bit stencil buffer.It also offers the industry’s only simultaneous
without performance loss.
