- * Driver: cb_pcimdas
- * Description: Measurement Computing PCI Migration series boards
- * Devices: [ComputerBoards] PCIM-DAS1602/16 (cb_pcimdas), PCIe-DAS1602/16
- * Author: Richard Bytheway
- * Updated: Mon, 13 Oct 2014 11:57:39 +0000
- * Status: experimental
- *
- * Written to support the PCIM-DAS1602/16 and PCIe-DAS1602/16.
- *
- * Configuration Options:
- * none
- *
- * Manual configuration of PCI(e) cards is not supported; they are configured
- * automatically.
- *
- * Developed from cb_pcidas and skel by Richard Bytheway (mocelet@sucs.org).
- * Only supports DIO, AO and simple AI in it's present form.
- * No interrupts, multi channel or FIFO AI,
- * although the card looks like it could support this.
