Design Checklist

•

For UP systems to support both the current Intel

®

 Pentium

®

 II processor and future 

processors, it is highly recommended that storage space for two (or more) BIOS Updates be 
provided. This will allow manufacturing flexibility to install either processor, the BIOS should 
detect the processor and load the correct BIOS Update.

•

For DP systems, it is recommended that storage for two (or more) BIOS Updates be reserved 
for the case where two different steppings of Slot 1 processors are installed. This will allow 
both processors to have BIOS Updates applied.

•

For the Intel

®

 Pentium

®

 II processor, an adequate heat sink and air ventilation must be 

provided to ensure that the processor TPLATE specification documented in the datasheet is 
met. See the Intel

 II Processor Power Distribution Guidelines, and Intel

 II Processor Thermal Design Guidelines for thermal design information.

•

For the Boxed processor, the system must have adequate air ventilation to ensure that the air 
intake temperature to the fan/heatsink is less than the maximum allowable fan preheat 
temperature (TPH) at the system maximum ambient temperature, measured 0.3” above the 
center of the fan. See the Intel

 II Processor Datasheet for the TPH Specification.

•

Verify that all major components, including the 82443GX can be cooled the way they are 
placed. Contact your local Intel Field Sales representative for the following Application Note: 
FW82443BX/FW82443GX PCI/AGP Controller Application Note #2: Thermal Design 
Considerations. This thermal application note contains thermal specifications, thermal 
solutions and the thermal test methodology for the 82443GX component.

•

Could anything block the air flow to or from the processor card (I/O cards, VRM etc.)? 

•

Is there anything between the processor and the air intake that may preheat the air flowing into 
the fan/heatsink? 

•

If a system fan (other than the power supply fan) is used, have all recirculation paths been 
eliminated? 

•

What is the air flow through the PSU/system fan?

•

What is the maximum ambient operation temperature of the system?

 II processor: The physical space requirements of the processor must 

be met. See the Intel

 II Processor Datasheet for details.
