I have this strange problem. The mainboard of my older computer is intel 440 BX (I know it's very old Very Happy ). It has 4 PCI slots. Two of the slots are used by sound card and TV tuner card. When I put third PCI device - LAN card no matter in which of the two remaining slots my computer doesn't start at all. Any suggestions? Thank you

The mainboard also has an AGP slot used by the video card, but I don't know if it's related with the problem somehow.

You have an IRQ Conflict. Which Windows operating system
are you using?

How are the IRQ's assigned in your BIOS?

The Interrupt Request is assigned to PCI cards by the BIOS. This IRQ value must then be communicated to the operating system. In order for a device to share.

I'm using Windows 98 SE operating system. The IRQ's are assigned automatically in the BIOS, and when the computer is booting there's a list of the PCI devices from which I can see the IRQ's values. They are the same as the one in Windows. When I set the assignment of the IRQ's to manual for every IRQ there are two options: PCI/PnP ISA and Legacy ISA. The interesting thing is that the display controller uses the same IRQ as the Multimedia controller but there are no conflicts reported between them. I guess that is because the devices use different slots - AGP and PCI. In BIOS there is an option to enable or disable assignment of IRQ to USB controller. It's enabled, maybe that matters. I still don't know how to solve my problem. By the way I'd like to learn more about the IRQ, and I'd be very glad if you can direct me to any sources of general information about the IRQ, Thank you

What LAN adapter are you trying to put in? Some older ones had fixed (or manually changeable) resources, if this is the case they could be conflicting with something else.
