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.
