SIV by Ray Hinchliffe. 'System Information Viewer' is a general Windows utility for displaying lots of useful Windows, Network and hardware info - CPU info, PCI info, PCMCIA info, USB info, Machine Info, Hardware Sensors, Networked computers, Operating System Information and more. I use pcidevs.txt for the PCI devices, usbdevs.txt for the USB devices, mondevs.txt for monitor descriptions and pcmdevs.txt for PCMCIA device descriptions. SIV is designed for Windows 7, Vista, XP, 2008, 2003, 2000 and NT4. Windows 95, 98 and Me are also supported.
