1.Hardware Engineering Specification

1.1 Introduction

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.

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 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.
