27 Driver: das08_cs
28 Description: DAS-08 PCMCIA boards
29 Author: Warren Jasper, ds, Frank Hess
30 Devices: [ComputerBoards] PCM-DAS08 (pcm-das08)
31 Status: works
32
33 This is the PCMCIA-specific support split off from the
34 das08 driver.
35
36 Options (for pcm-das08):
37 NONE
38
39 Command support does not exist, but could be added for this board.
