Sharing/Conflicts in Sytem Information

[JPett]

I went to check my system information the other day and i saw a conflict/sharing in IRQ 5. The conflict is as follows:

I/O Port 0x00000000-0x00000CF7 PCI bus
I/O Port 0x00000000-0x00000CF7 Direct memory access controller

IRQ 5 Realtek RTL8139 Family PCI Fast Ethernet NIC
IRQ 5 VIA Rev 5 or later USB Universal Host Controller
IRQ 5 VIA Rev 5 or later USB Universal Host Controller
IRQ 5 VIA Rev 5 or later USB Universal Host Controller
IRQ 5 VIA AC'97 Enhanced Audio Controller (WDM)

Memory Address 0xA0000-0xBFFFF PCI bus
Memory Address 0xA0000-0xBFFFF NVIDIA GeForce FX 5200

What can I do to make this conflict go away?

If you're not experiencing any problems with the devices listed, there isn't really a conflict.

"In Windows, peripheral component interconnect (PCI) devices can share IRQs. In accordance with the Plug and Play capability that is defined by the PCI specification, adapters are configured by the computer BIOS and are then examined by the operating system and changed if necessary. Typically, PCI devices have IRQs shared among them, especially on Advanced Configuration and Power Interface (ACPI) computers that have Windows ACPI support enabled.

In Windows XP, Device Manager may list some or all the devices on your ACPI motherboard as using the same IRQ (IRQ 9). (To view the list of resources, click either Resources by type or Resources by connection on the View menu). No option is available to change the IRQ setting. Windows takes advantage of the ACPI features of the motherboard, including advanced PCI sharing. The PCI bus uses IRQ 9 for IRQ steering. With this feature, you can add more devices without IRQ conflicts."

That and more in the MS KB article, A general description of IRQ sharing in Windows XP.

Well I was getting problems with USB ports.

The easiest thing to try first is simply to move the ethernet card to a different PCI slot. Uninstall it through Device Manager, shut the computer down, physically move the card to another slot, restart, reinstall the drivers.

I've use that trick successfully on several systems with IRQ conflicts...and I do like to try the simplest thing first.
