PCI resources are assigned by a PC's BIOS - they cannot be manually changed
in Windows Device Manager. Although PCI devices can share IRQs with each
other, this may sometimes cause problems so if you want to try to change the
IRQs or stop PCI devices sharing, you can try the following;

1. In the BIOS under "Integrated Peripherals", disable any devices not in
use. These could include COM1 (this will free up IRQ4), COM2 (this will free
up IRQ3), LPT1 (this will free up IRQ7), USB.

2. In the BIOS under "PCI/PNP Configuration", change the option "Resources
controlled by" from "Auto" to "Manual". You will now see a list of the IRQs
and beside each, will state whether that IRQ can be used by "ISA/Legacy" or
"PCI/ISA PnP". Set as many IRQs as possible to "PCI/ISA PnP" instead of
"ISA/Legacy".

3. Start Windows and check in Device Manager if the devices in question are
still sharing. If they are, now try the cards in different PCI slots.
Usually, the first PCI slot will share an IRQ with the AGP slot and the last
PCI slot will share an IRQ with USB.

If none of this works, perhaps try updating the PC's BIOS and try changing
"PnP OS Installed" between "Yes" and "No".

In some cases, the BIOS will allow you to assign a particular IRQ to a
particular PCI slot but this is usually not the case.
The BIOS options named above are unfortunately not always the same for every
type of BIOS but there are usually similar options.

If after this it is still not possible to change IRQs, there is nothing else
to be done as it is the BIOS which is allocating the resources.
