Driver: das08_cs
Description: DAS-08 PCMCIA boards
Author: Warren Jasper, ds, Frank Hess
Devices: [ComputerBoards] PCM-DAS08 (pcm-das08)
Status: works
This is the PCMCIA-specific support split off from the
das08 driver.
Options (for pcm-das08):
NONE
Command support does not exist, but could be added for this board.
