Overview
Compatibility in a system can be impacted by many factors including computer BIOS, Windows settings, and signal path within the computer and cable. This technical note provides the detailed BIOS and Windows settings for modular systems using the tested computers that are compatible with Keysight Technologies, Inc. PXI/AXIe chassis. This document is an extension to the Tested PC and PXI/AXIe Chassis Configurations for users who need special BIOS and Windows settings to optimize their systems for compatibility. Refer to tables below for specific detailed BIOS and Windows settings for each tested computer.
