    'ello, everyone. I've been racking my brain out about this
    problem, and I'm hoping someone on the list can help out. I've
    searched around the archives for similar problems, and found a few,
    but no solutions offered worked for me. So here goes.

    I've got a Philips CDD-3610 CD Burner I'd like to hook up to my
    Linux box, currently running kernel 2.4.4-ac4. Before I do anything,
    here's my module list (just stuff for my sound card):

    > [root@gaia /root]# lsmod
    > Module Size Used by
    > cs4232 3056 0
    > uart401 6096 0 [cs4232]
    > ad1848 16560 0 [cs4232]

    The CDD-3610 uses the EPAT protocol, and everything looks good when
    I modprobe that module:

    > [root@gaia /root]# modprobe epat
    > [root@gaia /root]# lsmod
    > Module Size Used by
    > epat 6048 0 (unused)
    > paride 3712 1 [epat]
    > parport 13760 0 [paride]
    > cs4232 3056 0
    > uart401 6096 0 [cs4232]
    > ad1848 16560 0 [cs4232]

    When I try to load the pg module, however, things go haywire:

    > [root@gaia /root]# insmod pg drive0=0x378,0
    > Using /lib/modules/2.4.4-ac4/kernel/drivers/block/paride/pg.o
    > /lib/modules/2.4.4-ac4/kernel/drivers/block/paride/pg.o: init_module: Operation not permitted
    > Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters

    The output from dmesg looks okay up until that point as well:

    > [root@gaia /root]# dmesg | tail
    > paride: version 1.06 installed (parport)
    > paride: epat registered as protocol 0
    > pg: pg version 1.02, major 97
    > PnPBIOS: Parport found PNPBIOS PNP0401 at io=0378,0778 irq=7 dma=3
    > parport0: PC-style at 0x378, irq 7 [PCSPP(,...)]
    > pg0: Adapter not found
    > pg: No ATAPI device detected

    Just to be sure, I checked to make sure that 0x378 was the correct
    address of my parallel port, and that /dev/pg0 was set up properly,
    and it looks like everything is:

    > [root@gaia /root]# ls -l /dev/pg0
    > crw------- 1 root sys 97, 0 Apr 17 1999 /dev/pg0
    > [root@gaia /root]# cat /proc/ioports | grep parport
    > 0378-037a : parport0

    Can anyone help me out with this? Many thanks
    in advance . . .
