| Driver: adl_pci7296 |
| Description: Driver for the Adlink PCI-7296 96 ch. digital io board |
| Devices: [ADLink] PCI-7296 (adl_pci7296) |
| Author: Jon Grierson <jd@renko.co.uk> |
| Updated: Mon, 14 Apr 2008 15:05:56 +0100 |
| Status: testing |
| |
| 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. |
