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.
