- * This is a rewrite of the das08 and das08jr drivers.
+ * This driver is used by the das08_isa, das08_cs, and das08_pci
+ * drivers to provide the common support for the DAS-08 hardware.
*
- * Options (for ISA cards):
- * [0] - base io address
- *
- * Manual configuration of PCI cards is not supported; they are
- * configured automatically.
- *
- * The das08 driver doesn't support asynchronous commands, since
- * the cheap das08 hardware doesn't really support them. The
- * comedi_rt_timer driver can be used to emulate commands for this
- * driver.
