23 Driver: contec_pci_dio
24 Description: Contec PIO1616L digital I/O board
25 Devices: [Contec] PIO1616L (contec_pci_dio)
26 Author: Stefano Rivoir <s.rivoir@gts.it>
27 Updated: Wed, 27 Jun 2007 13:00:06 +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.
