Dell Inspiron 8500: missing CD/DVD drive when docked!

    I just reinstalled WinXP Pro on my Inspiron 8500. I installed it with
    the laptop undocked and all is well. I even installed the Dell
    Notebook System Software. When I dock the laptop, my CD/DVD drive
    (Matshita UJDA740) ceases to appear in My Computer, Device Manager,
    Explorer, etc. The Secondary IDE Channel also starts to show an IRQ
    conflict with COM1. Manually changing COM1's IRQ and/or disabling it
    don't have any effect. Dell says that the dock (PR01X) is defective.
    However, my dock works on the laptops at work, and a known good dock
    from work, doesn't work with my laptop. In reading the forums at
    support.dell.com, I see several others with this issue, but no
    resolution. I'm going to try to delete the upper and lower filters in
    the registry this afternoon when I get home. Does anyone have any
    other suggestions? Thanks in advance.

    This is just a WORK around.
    Change the Driver for the COM port to be a Standard Printer. This
    will free up any IRQs, and then the Secondary IDE Controller will
    work. I know this is a Dell problem, and this is NOT a solution, it's
    just a workaround if you don't use your COM port very often.
