    I just finished flashing my BIOS and it went fine. I then went to the System Information tool and selected the IRQ tab. IRQ11 was being shared by 3 devices before I flashed, now it is being shared by 6. Here is the list of my IRQs.

    IRQ 0 System timer OK
    IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard OK
    IRQ 3 Communications Port (COM2) OK
    IRQ 4 Communications Port (COM1) OK
    IRQ 6 Standard floppy disk controller OK
    IRQ 8 System CMOS/real time clock OK
    IRQ 11 Microsoft ACPI-Compliant System OK
    IRQ 11 NVIDIA GeForce4 Ti 4600 OK
    IRQ 11 VIA Rev 5 or later USB Universal Host Controller OK
    IRQ 11 VIA Rev 5 or later USB Universal Host Controller OK
    IRQ 11 VIA AC'97 Audio Controller (WDM) OK
    IRQ 11 Creative SB Live! Value (WDM) OK
    IRQ 11 Lucent Win Modem OK
    IRQ 13 Numeric data processor OK
    IRQ 14 Primary IDE Channel OK
    IRQ 15 Secondary IDE Channel OK

    Before flashing it was just my Geforce4 and the 2 USB ports sharing IRQ11. Is there a way to change this?

    Hi Zulli85, Welcome to TSG !!
    Not to worry, win 2000 and XP do a very good job at sharing IRQ's! Mine in win2000 are set up the same. No probs yet.

    I'm glad you're so confident, hehe :p ;) :D j/k

    If it does bother you at all, and you do notice a decline in performance, then you can change IRQ's in the BIOS itself.

    After flashing the BIOS, it sets itself up with all the default settings.

    I don't know if you intended it, but notice how your onboard audio chip is enabled and sharing IRQ11 with your sound card.

    If you don't use it, you can disable the VIA AC'97 onboard controller in:
    BIOS Setup -> Inegrated Peripherals
    (change AC'97 to "disabled")

    You should be able to assign IRQ's for the PCI slots in:
    PNP/PCI Configuration
    Default settings are AUTO

    As it stands at the moment, all your PnP/PCI cards are using IRQ11.

    Another method is to move the pci cards to different (previously unused) slots.
    Currently, you're using two of the slots (sb live & win modem), so you should have 2 or 3 spare.
    Naturally, first check in "BIOS -> PnP/PCI Config" that all slots aren't using IRQ11.

    "Plug and Play Aware O/S" should be set to "yes"
    (some bios are known to set this to "no" by default)

    imho, it's not good for video and audio devices to share the same IRQ, not to mention the modem as well . . . but hey, that's Windows ACPI for ya . . .
