24 Description: Driver for the Adlink PCI-7296 96 ch. digital io board
25 Devices: [ADLink] PCI-7296 (adl_pci7296)
26 Author: Jon Grierson <jd@renko.co.uk>
27 Updated: Mon, 14 Apr 2008 15:05:56 +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.
