K7VTA3 V8.0 IRQ issue

    I'm running my K7VTA3 v8.0 with a Sempron 3000+ and Win2000 Pro. While
    investigating a problem with games freezing up (eventually require a total
    system rebuild), I noticed that IRQ 7 was shared by my TI 4200U video card,
    onboard LAN, USB Host (x2) and SoundBlaster Live 5.1 card. However, IRQs 5
    and 11 are not being used. This seems like a recipe for disaster. I logged
    in as the Administrator and went into Device Manager to select different
    configurations for these devices but the selections for each one were greyed
    out. This seemed strange as I remember over the years with Win98 being able
    to mess with the configs to get rid of device conflicts. I wanted to move
    some of these devices to IRQ 5 and 11. In the BIOS, these two IRQs were not
    reserved but were set up as the others for PCI cards. I tried resetting the
    ECSD as well as setting the BIOS to "Plug and Play OS installed." Everytime
    I rebooted and even after a total system rebuild, IRQs 5 and 11 were not
    used. The onboard audio is disabled in the bios as is the serial and
    parallel ports. I even tried reserving IRQs 5 and 11 but this obviously
    didn't help. I did not try to reserve IRQ 7 to force the system to
    reallocate the devices...I guess I didn't want to have another crash.

    Well, I'm wondering if anyone else has run into this problem and found a
    solution to utilize these other IRQs to prevent so many devices hanging off
    the same IRQ. Seems very odd to me. I've been able to make SB cards use
    IRQ 5 back in the day but not with this board. I'm not sure if its the
    mainboard and/or its settings, the OS, the devices themselves, or my lack
    of knowledge.

    Any help would be greatly appreciated.

    Oops, I almost forgot. I moved the SB Live card to 3 different PCI slots in
    case the IRQs were tied to specific slots. This didn't make a difference.
    The SB Live went straight to IRQ 7 each time. Currently the SB Live is in
    the third slot from the bottom and working fine.

    Thanks again for any help.
