This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy. If not installed and used properly, in strict accor-
dance with the manufacturer’s instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures :
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/television technician for help and for additional suggestions.
The user may find the following booklet prepared by the Federal Communications Commission helpful “How to Identify
and Resolve Radio-TV Interference Problems.” This booklet is available from the U.S. Government Printing Office.

HOT-637isa highly integratedIBMPC/AT compatiblesystemboard
designed to meet the industry's most demanding desktop applications.
Basedonthe Intel 82440LXAGPsetchipset, theIntelPentiumTMIIprocessor with
MMXtechnologyfeatured, and256KBor 512KB Level2 high-performance pipelined
burstsecondary168-pin DIMM socketandsupports up to512MBof EDO RAMand
SDRAM.
HOT-637isequipped withan AcceleratedGraphicsPort(A.G.P.), ahigh-performance
interconnectforgraphic-intensiveapplication,such as3D applications.TheA.G.P. is
independentofthe PCI busandis designedtoexclusively use withgraphical-display
devices.TheHOT-637 supports3.3V A.G.P.deviceswith datatransferrates upto133

The Pentium™ II & Celeron™ Processor
ThePentiumII and Celeron processoristhe next memberofthe P6 processorfamily. It
combinesthearchitecturaladvancesinthePentium Proprocessor withthe instructionset
extensionsofMMX technology. It isfullycompatible withthehuge base ofIntelarchitec-
ture-basedPCsoftware. Additional, the PentiumII processor deliversnewlevels ofperfor-
manceforadvance mediaand communicationssoftwareincluding powerful,realistic
graphicsandimaging capabilities, videoconference,and theabilityto run full-screen,full-
motionvideo. Thecombination oftheseadvanced technologiesmakes thePentiumII
