+.SH NAME
+/proc/pci \- PCI devices
+.SH DESCRIPTION
+.TP
+.I /proc/pci
+This is a listing of all PCI devices found during kernel initialization
+and their configuration.
+.IP
+This file has been deprecated in favor of a new
+.I /proc
+interface for PCI
+.RI ( /proc/bus/pci ).
+It became optional in Linux 2.2 (available with
+.B CONFIG_PCI_OLD_PROC
+set at kernel compilation).
+It became once more nonoptionally enabled in Linux 2.4.
+Next, it was deprecated in Linux 2.6 (still available with
+.B CONFIG_PCI_LEGACY_PROC
+set), and finally removed altogether since Linux 2.6.17.
