which slots share IRQ's

I have a Micro-Star K7T Pro2-a (MS-6330) mother board
Can anyone tell me wich PCI slots share IRQ's. I believe the AGP slot shares with PCI no.1 and also the USB ports. Not shure about the rest but would like to know, thanks.

check your motherboard manual.

check or post in the newsgroups

you won't find the info on msi's site or in the manual

that kinda stuff you have to dig real deep for

email a tech at MSI, or ask in the official newsgroup for their mobos

Do a System Info and select Hardware Resources by IRQ's and you will see which ones are being shared.

I found this on a news group:
BIOS V1.6 has USB and AGP on separate IRQ's.
However all the other BIOS versions lock
(or dump) AGP and USB into one IRQ.
>PIN 1 = AGP
>PIN 2 = PCI Slot 1 (shared with PCI Slot 4)
>PIN 3 = PCI Slot 2 (shared with on board sound)
>PIN 4 = PCI Slot 3 (shared with USB)
>PIN 2 = PCI Slot 4 (shared with PCI Slot 1)
>PIN 3 = PCI Slot 5 (shared with on board sound)
>PIN 4 = PCI Slot 6 (shared with USB)

In short:
AGP, slot 3 & slot 6 share (in versions other than 1.6)
Slot 1 & Slot 4
Slot 2 & Slot 5

I went into sys info and most devices are on IRQ 7, thats what got me started on this. My os is win 2k.

At present i have as follows:
pin 1 AGP voodoo 5500
pin 2 PCI 1 empty
pin 3 PCI 2 empty
pin 4 PCI 3 D-link NIC
pin 2 PCI 4 Sound blaster live value
pin 3 PCI 5 ADS usb ver 2.0
pin 4 PCI 6 empty (usb 1.1 MB header)

Bios shows int pin 1 Display controller, pin 2 multimedia device, pin 3 serial bus controller, pin 4 network controler, which agrees with the above. Pin 1 also listed 3 serial devices which i believe are on board usb. My bios is V3.4. I beleave the AGP is tied to the usb but i don't think it is tied to slots 3 and 6. There are 4 pin assingments in the bios, there would only be 3 if it was.

My plan is to put my cards in so they don't share a pin assignment and manualy set the IRQ's to the pin in the bios.
Wish me luck, i may need it.

Thank's for the reference. I had read that thread, it sort of started me on this endever. I do plan to wait untill i have to do a clean install. May be a while, knock on wood. Win 2k seems to be very stable, at least on my system.
