23 | PCMCIA support code for this driver is adapted from the dummy_cs.c |
24 | driver of the Linux PCMCIA Card Services package. | |

35 | Description: DAS-08 PCMCIA boards | |
36 | Author: Warren Jasper, ds, Frank Hess | |
37 | Devices: [ComputerBoards] PCM-DAS08 (pcm-das08) | |
38 | Status: works | |
39 | ||
40 | This is the PCMCIA-specific support split off from the | |
41 | das08 driver. | |
42 | ||
43 | Options (for pcm-das08): | |
d539047c | 44 | NONE |

45 | |
46 | Command support does not exist, but could be added for this board. | |
