Tool that provides services to DLLs to access the PC system hardware. Includes a collection of DLLs performing low-level hardware access to identify and control PC components via I/O, linear address space and CPU registers. Scans the PC hardware directly, bypassing the O/S and provide real-time H/W info. Current libraries include ACPI with AML Source decoder, PCI configuration space browser and PCI tests, SMBIOS browser and structure type validation, Multiprocessor table decoder, BIOS legacy tables decoder, APIC/PIC information, CMOS bank decoder, CPU MSR registers editor, Physical memory and file Disassembler, Windows process viewer, I/O editor with script processing, Physical Memory editor with script processing. Watches to probe Ports, Physical memory, MSR registers, ACPI I/O objects, CMOS registers, PCI registers. Timing Checks for Ports and Memory. CPU tests for MMX, FPU, General instructions and memory access. PCI tests for SERR#, PERR#, floating bus failures and error logging.
