My laptop is FOSA CL10 and it have two 02Micro
OZ6933 pcmcia controllers. I have installed RH7.3
on my machine. I must disable the pcmcia service
in /etc/sysconfig/pcmcia, otherwise my machine
freezes completly when OS boot and detect the
PCMCIA controllers. The boot messages shown as
following: "Starting pcmcia: PCI: NO IRQ know for
interrupt pin A of device 02:04.0.0 please try using
pci=biosirq" and "PCI: NO IRQ know for interrupt
pin B of device 02:04.0.0 please try using
pci=biosirq". I have tried to add "pci=biosirq"
in /etc/sysconfig/pcmcia file but it doesn't work.
Please some body help me to resolve the problem.
Thanks a lot.

    Check your BIOS settings; if you have one for "PnP OS
    support", try changing that.

    Hi, Dave --

    There is no "PnP OS support" option in my BIOS.
    Do you have other comments?
    thanks.

    The "NO IRQ" problem is a persistent kernel bug/limitation
    and I don't know of a good workaround. You may have better
    luck if you can delete the kernel PCMCIA modules and install
    the standalone pcmcia-cs modules. But those may not work
    on this laptop either. Running an ACPI kernel may help but I
    don't know which kernel versions have the appropriate level of
    ACPI support.

    I believe that either using a current 2.5 kernel or the latest
    ACPI patches for 2.4 kernels would be likely to help. You
    can get patches for 2.4 kernels from
    http://acpi.sourceforge.net. You may need to then boot with
    a "pci=acpi" option though I can't find much documentation
    on that.
