Re: Cdrom Problems

["Jens B. Jorgensen" <jjorgens@bdsinc.com>]

I'm guessing when you set up support for the device you didn't pass
parameters for it. Unfortunately for this device this is necessary since
the driver can't/won't autoprobe for the device. Here's the snippet from
the CDROM-Howto:

  4.3.3.  Cdu31a Driver



         Principal author: Corey Minyard (minyard@-rch.cirr.com)
    Multi-session support: yes
   Multiple drive support: no
  Loadable module support: yes
     Reading audio frames: yes
             Auto-probing: no
              Device file: /dev/cdu31a, major 15
       Configuration file: cdu31a.h
     Kernel config option: Sony CDU31A/CDU33A CDROM support?
              README file: cdu31a




  This driver accepts a kernel command line of the form:



       cdu31a=<io-address>,<interrupt>,PAS
  The first number is the I/O base address of the card (e.g. 0x340). The

  second is the interrupt number to use (0 means to use polled i/o). The

  optional third parameter should be "PAS" if the drive is connected to
  a Pro-Audio Spectrum 16 sound card, otherwise left blank.

  If the driver is loaded as a module, it uses a slightly different
  format. When loading the driver using the modprobe or insmod command,
  the parameters take the form:

       cdu31a_port=<io-address> cdu31a_irq=<interrupt>

  The base io-address is required while the interrupt number is
  optional.
  The device file can be created using:

       # mknod /dev/cdu31a b 15 0

  See the file cdu31a for more information on this driver.

  Also see the Web page put together by Jeffrey Oxenreider
  (zureal@infinet.com) that covers a lot of common problems with these
  drives. It can be found at
