Debug Recommendations

This chapter provides tool information, logic suggestions, technical support options and a summary of the problems which have been found to be associated with system debug. Although not comprehensive in scope, the recommendations are included to preclude unnecessary expenditures of time and effort during the early stages of debug. While the methodologies suggested are those which Intel believes are most likely to be successful, they are not a substitute for correct design practices nor are they a substitute for other Intel references.

4.1Slot 1 Test Tools

The Slot 1 Test Kit, consists of the following test tools:

•The Slot 1 Electrical/Mechanical/Thermal (EMT) Test Tool, which provides mechanical, thermal and voltage transient testing capabilities

•The Slot 1 Continuity Test Tool (CTT), which provides continuity testing capabilities for the Slot 1 connector.

4.2Debug/Simulation Tools

4.2.1Logic Analyzer Interface (LAI)

Logic analyzer interface modules provide a way to connect your logic analyzer to signals on the processor system bus. They are available from two logic analyzer vendors:

•Hewlett-Packard Co. for their HP-16500B* series logic analyzers. Contact your local Field Sales representative to set up a three way non-disclosure agreement to begin discussions with Hewlett-Packard on their product. This product is purchased directly from Hewlett-Packard.

•Tektronix for their DAS/NT*, DAS/XP*, and TDS 700 series logic analyzers. Contact your local Field Sales representative for availability of the LAI565T interface module for the Intel® Pentium® II processor from Intel. The LAI562T interface module is designed for the Intel® Pentium® II processor. The DAS* software is available directly from Tektronix.

Contact your local Intel Field Sales representative to complete the proper non-disclosure agreement required to receive the LAI.

4.2.2In-Target Probe (ITP)

The ITP565 provides a software debug capability allowing the setting/clearing of hardware/ software breakpoints, assembly/disassembly of code, display/modification of the processor register set, display/modification of system memory, display/modification of I/O space and includes a macro language for custom debug procedure creation, etc. Contact your local Field Sales representative for availability of this tool from Intel.

440GX specifications

The Intel 440GX chipset was launched in 1997 as part of Intel's series of chipsets known as the 440 family, and it served as a critical component for various Pentium II and Pentium III-based motherboard architectures. Specifically designed for the second generation of Intel’s processors, the 440GX delivered enhanced performance and supported a range of important technologies that defined PC architectures of its time.

One of the main features of the Intel 440GX was its support for a 100 MHz front-side bus (FSB), which significantly improved data transfer rates between the CPU and the memory subsystem. This advancement allowed the 440GX to accommodate both the original Pentium II processors as well as the later Pentium III chips, providing compatibility and flexibility for system builders and consumers alike.

The 440GX chipset included an integrated AGP (Accelerated Graphics Port) controller, which supported AGP 2x speeds. This enabled high-performance graphics cards to be utilized effectively, delivering many enhanced graphics capabilities for gaming and multimedia applications. The AGP interface was crucial at the time as it offered a dedicated pathway for graphics data, increasing bandwidth compared to traditional PCI slots.

In terms of memory support, the 440GX could address up to 512 MB of SDRAM, allowing systems built with this chipset to run comfortably with sufficient memory for the era’s demanding applications. The memory controller was capable of supporting both single and double-sided DIMMs, which provided versatility in memory configuration for system builders.

Another notable feature of the Intel 440GX was its support for multi-processor configurations through its Dual Processors support feature. This allowed enterprise and workstation computers to leverage the performance advantages of multiple CPUs, making the chipset suitable for business and professional environments where multitasking and high-performance computing were essential.

On the connectivity front, the chipset supported up to six PCI slots, enhancing peripheral device integration and expansion capabilities. It also included integrated IDE controllers, facilitating connections for hard drives and CD-ROM devices.

Overall, the Intel 440GX chipset represented a balanced combination of performance, flexibility, and technology advancements for its time. Its introduction helped establish a foundation for subsequent advancements in PC technology and set the stage for more powerful computing systems in the years to come.
