HOT-687
computer mainboard.
HOT-687 is a highly integrated IBM PC/ATX compatible system board designed to meet the industry's
most demanding desktop applications.
Based on the Intel 82440BX AGPset chipset which support up to 500MHz PPGA Celeron processor
with MMX technology.
HOT-687 is equipped with an Accelerated Graphics Port (A.G.P.), a high-performance interconnect
for graphic-intensive application, such as 3D applications. The A.G.P. is independent of the PCI bus
and is designed to exclusively use with graphical-display devices. The HOT-687 supports 3.3 V
A.G.P. devices with data transfer rates up to 133 MHz, allowing data throughput of 500 MB/sec.
The Intel's 82440BX 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 IrDA device port and a SPP/EPP/ECP capable
parallel port.
HOT-687 is built with three PCI local bus slots providing a high bandwidth data path for data-
movement intensive functions such as graphics, and with one ISA slot.
HOT-687 provides the foundation for cost effective, high performance and highly expandable plat-
forms, which delivers the latest in the Intel PPGA Celeron processor and new advanced chipset
technology.
