Numeric processing extension coprocessor and emulator
Usage

Overview
The npx driver enables the use of the system's Numeric Processing Extension coprocessor, if one is present. Numeric processing extensions are present in systems with 486DX CPUs and in systems with 387 or 487SX coprocessors. The npx driver is required for proper system functioning regardless of whether or not an NPX is present.
