Using the PCI hot-plug interface
You can use the open-source PCI hot-plug graphical interface application
(pcihpview) to perform hot-plug operations and to view the status of each of the PCI
slots.
You can obtain a copy of the pcihpview application at
http://www.ibiblio.org/pub/linux/X11/xutils. The instructions for building the pcihpview
GUI are included in the compressed image.
Complete the following steps to perform a hot-plug operation using the interface:
1. Make sure that the PCI hot-plug device drivers and pcihpfs file system are
loaded (see “Loading the PCI hot-plug device driver” on page 21); then, type the
