+Driver: adl_pci7230
+Description: Driver for the Adlink PCI-7230 32 ch. isolated digital io board
+Devices: [ADLink] PCI-7230 (adl_pci7230)
+Author: David Fernandez <dfcastelao@gmail.com>
+Status: experimental
+Updated: Mon, 14 Apr 2008 15:08:14 +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.
