and PXI Express chassis. If PCI bus
num-bers are occupied, the system may not boot
correctly, or
devices will not be detected.
Theoretically, PC systems implementing PCI Express can
support up to 256 bus numbers. However, the maximum
PCI bus numbers of many PC systems are frequently lim-
ited by the system BIOS based on the system design or
architecture. Conversely, the PXI Express chassis con-
sumes many PCI bus numbers. Each PXI Express periph-
eral slot reserves a PCI bus number, and PCI Express
switches on a PXI Express chassis also occupy several PCI
bus numbers. Some peripheral modules may also consume
PCI bus numbers. PCI bus number requirements for
JYTEK
PXI Express chassis are as shown.

Third party utilities like System Information Viewer (http://rh-

bers in the system BIOS (Run SIV>>PCI Bus>>ACPI
