HOT-685Z is a highly integrated IBM PC/AT compatible system board designed
to meet the industry's most demanding desktop applications.
Based on the Intel 82443ZX AGPset chipset which support up to 500MHz PPGA
Celeron processor with MMX technology.
HOT-685Z is equipped with an Accelerated Graphics Port (A.G.P.), a high-
performance interconnect for graphic-intensive application, such as 3D applica-
tions. The A.G.P. is independent of the PCI bus and is designed to exclusively
use with graphical-display devices. The HOT-685Z supports 3.3V A.G.P. de-
vices with data transfer rates up to 133 MHz, allowing data throughput of 500
MB/sec.
The Intel's 82443ZX AGPset chipset provides an integrated Bus Mastering IDE
controller with two high performance IDE interfaces which allows up to four IDE
devices connection and up to 33 MB/sec of data transfer rates.
Onboard FM801 is an advanced PCI audio controller, it is compatible with
Microsoft Windows, DirectX and Adlib Music Synthesizer, Sound Blaster Pro
and supports thousands of DOS games.
The on-board I/O controller provides standard PC I/O functions:
floppy drive interface, two FIFO serial ports, an InDA device port and a SPP/
EPP/ECP capable parallel port.
HOT-685Z is built with four PCI local bus slots providing a high bandwidth data
path for data-movement intensive functions such as graphics, and with one ISA
slot.
HOT-685Z provides the foundation for cost effective, high performance and
highly expandable platforms, which delivers the latest in the Intel PPGA Celeron
processor and new advanced chipset technology.
