    Issues with EW-7622UMn and BIOS

    I recently bought this Edimax EW-7622UMn wireless stick because I needed one and it said it supported Linux.
    There was an included linux driver that actually compiled rather well. At first I had problems with a missing wlan0 in iwconfig, but I solved that now. My new problem consists of this output after "sudo ifconfig wlan0 up":

    SIOCSIFFLAGS: Resource temporarily unavailable

    This is what google spit out:

    ----

    The Netgear LNX100TX has a known issue with the tulip driver on a PNP
    bios -- it gets an invalid IRQ assignment. Confirm this by checking
    /proc/interrupts.

    The solution is to set the IRQ via BIOS, either directly (if possible)
    for the PCI slot, or by disabling PNP altogether.

    I ran across this very problem tonight. Card's now happily configured
    with IRQ 10.

    ----

    A few other people said pretty much the same thing, namely to disable Plug and Play(PnP) in the BIOS.
    I just can't find it!!!
    Please tell me how to find the disable button or how to solve this problem without the BIOS.

    Thank you.

    Misc. information:
    I have a Ultra Durable 3 classic something motherboard (not sure) and here is my /proc/interrupts:
