  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.
