    Hi,

       I am writting a module that sits in the kernel, and probes the CD Rom
    drive after X time intervel. The moment it finds some sort of disk - Data,
    Audio, etc, it tries to load the appropriate module. By writting this
    module, the user does not have to mount the CD rom. It will be done
    _automatically_ once the disk is put in.

      There are two problems:

    1) I am not able to find as to how and in which file are the timer
    interrupts handled.

    2) As it happens in windows, I am trying to catch th interrupt generated
    when the CD rom drive shutter is closed. This way, I don't have to probe any
    more. However, I am not able to find any interrupt being generated by the
    device driver on closing the CD Rom drive.

       Any help in this direction would be much appreciated.

       -Siddharth.
