What Navrátil Software System Information is

Navrátil Software System Information (NSSI) is a free Windows utility that reports computer hardware and system details. It is intended for technicians, people considering a computer purchase or upgrade, and users searching for drivers. NSSI can inspect a computer without an operating system, and the maker says it can run from a system diskette or USB flash disk. Its inventory covers the mainboard, CPU and cache, BIOS, video, memory, storage, network, sound, ports, and devices on several bus types, including PCI, AGP, and PCMCIA. It also reports OS and DOS information, loaded drivers, and TSRs. CPU and FPU benchmark tests and tools for checking CPU bugs are included. The product page lists support for 48-bit LBA and disks up to 128 PB. Memory type and memory-slot details depend on the chipset. Version 0.60.47 is listed as a recommended upgrade.
