27 Driver: ni_65xx
28 Description: National Instruments 65xx static dio boards
29 Author: Jon Grierson <jd@renko.co.uk>, Frank Mori Hess <fmhess@users.sourceforge.net>
30 Status: testing
31 Devices: [National Instruments] PCI-6509 (ni_65xx), PXI-6509, PCI-6510, PCI-6511,
32 PXI-6511, PCI-6512, PXI-6512, PCI-6513, PXI-6513, PCI-6514, PXI-6514, PCI-6515,
33 PXI-6515, PCI-6516, PCI-6517, PCI-6518, PCI-6519, PCI-6520, PCI-6521, PXI-6521,
34 PCI-6528, PXI-6528
35 Updated: Wed Oct 18 08:59:11 EDT 2006
36
37 Based on the PCI-6527 driver by ds.
38 The interrupt subdevice (subdevice 3) is probably broken for all boards
39 except maybe the 6514.
