24 Description: Driver for the Adlink PCI-7432 64 ch. isolated digital io board
25 Devices: [ADLink] PCI-7432 (adl_pci7432)
26 Author: Michel Lachaine <mike@mikelachaine.ca>
28 Updated: Mon, 14 Apr 2008 15:08:14 +0100
30 Configuration Options:
31 [0] - PCI bus of device (optional)
32 [1] - PCI slot of device (optional)
33 If bus/slot is not specified, the first supported
34 PCI device found will be used.
