A. There are some problems with BIOS settings when NT is being installed on a machine designed for Windows 95/98
There have been a number of cases where frustrated users had trouble installing network cards and such for NT on machines designed for windows 95/98 (like HP Pavillion, etc). Usually, there is a simple BIOS setting that lets you specify whether the OS is PNP compliant. Setting this to "No" or "Other" usually takes care of most problems.
