In Reply to: USB K7TPro and IRQ sharing posted by Cyril Thibout on 05/27/02 at 3:49 PM:
Unfortunately MSI didn't document the pci irq. It looks like that AGP and USB using the same irq and there is no way to change this.
Check your bios version, if you got an older version (<3.2), update it. There was a problem with ACPI and WinXP.
: Before even configuring windows XP (put in 'standard PC' mode with whatever IRQ policy) I notice that both USB controllers SHARE in the BIOS the same IRQ as the AGP GeforceDDR
: It means that even before entering windows I already have an IRQ conflict I don't knwo how to solve.
: I put the IRQ attribution to 'auto'.
: The USB (other devices) works but I would prefer using another free IRQ (I freed COM1 and parallel port just for that but these IRQ are still unused). The bios prefers sharing the AGP IRQ rather than using a free IRQ!!
: Is there a way to force in the BIOS the USB IRQ ?
: Whatever IRQ I choose for the AGP card it will be the same for the USB controllers!
: Thanks a lot
