+Description: Driver for the Adlink PCI-8164 4 Axes Motion Control board
+Devices: [ADLink] PCI-8164 (adl_pci8164)
+Author: Michel Lachaine <mike@mikelachaine.ca>
+Status: experimental
+Updated: Mon, 14 Apr 2008 15:10:32 +0100
+
+Configuration Options:
+ [0] - PCI bus of device (optional)
+ [1] - PCI slot of device (optional)
+ If bus/slot is not specified, the first supported
+ PCI device found will be used.
