    Default HD 4850 UAA Bus driver IRQ change???!!!!

    ok i can run all games just fine but i get a Exclamation sign in device manager...at "Microsoft UAA Bus driver for high Definition" which belongs to ATI HD 4850.

    Another "Microsoft UAA Bus driver for high Definition" belongs to my realtek HD integrated sound device. < this has no yellow sign on it

    I have to disable Both USB controller and PCI-e LAN card(motherboard builtin) to make the exclamation sign go away.

    SO ITS NOT ABOUT INCOMPATIBLE DRIVER RATHER ITS ABOUT IRQ SHARING.


    if i keep either usb controller or PCI-e lan card on in bios the exclamation sign comes back and only goes away if both usb controllerand PCI-Elan card is turned off.

    The yellow signed device has a message in the properties like this "This device cannot find enough free resources that it can use. (Code 12)

    If you want to use this device, you will need to disable one of the other devices on this system.
    "

    im using intel 915 PL chipset and No pci card installed.....

    DO guyz think im out of IRQ or is there any workaround??

    IRQ conflicts can always randomly occur due to the motherboard not allocating resources properly... i suggest you update ur motherboard bios (it solved the problem for me) and/or reinstall ur operating system

    well i have the driver nd trust me its not the driver "Microsoft UAA Bus Driver for High Definition Audio"

    just figured out that ACPI allocates IRQ in XP and thus it wont allow manuall interference.

    Few days back installed windows 7 build 7000 nd has the same yellow mark.

    Btw i flashed my bios the day i saw this yellow mark....didnt work either. TRIED bios version 0901 for Asus P5GPL.

    edit-------------------

    there is another bios >>>ASUS P5GPL BIOS 1009 Beta but its dated at 2007/01/10 @ http://drivers.softpedia.com/get/BIO...009-Beta.shtml

    where the 0901 is dated at same 2007/01/10 at asus website confused.

    well...its a weird situation i must say

    flash to the other bios you mentioned, and from the situation it definitely is a situation where resources are not being properly allocated...did u try tinkering with the irq settings in the bios? flash to the latest one and try it out
