MXI-Express BIOS Compatibility Software works around common BIOS limitations; however, not all possible limitations can be managed. Among the configurations that MXI-Express BIOS Compatibility Software cannot compensate for, some can be detected in advance (prior to installation of software), including:
The installer for MXI-Express BIOS Compatibility Software checks for these issues and alerts detection through pop-up messages. In the case of multiple root bus devices, installation is prevented.
Note: MXI-Express BIOS Compatibility Software versions 1.4 and newer do support multi-root bus systems, though the MXIeBusDetect utility may suggest otherwise when run on certain systems. An alternative to detect these issues in advance is to use a stand-alone application, the MXI Express Compatibility Root Bus Detection Utility, which is attached to this article. It will provide information about the system's PCI/PCI Express root bus devices and the implications of any detected issues. You should only use the version of the MXIeBusDetect executable that corresponds to your version of Windows. 32-bit versions of Windows should use the MXIeBusDetect_32bit.exe utility, and 64-bit versions of Windows should use the MXIeBusDetect_64bit.exe utility.
