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