I have a 1394 IEEE host controller installed on my computer with Win2000 and the IRQ is 11, along with several other items like sound card, 3D Labs permedia3 Create and VIA USB Universal Host Controller.  I can't get my video camera to be recognized by my computer to input video.  I read some information about making sure my 1394 card is on its own IRQ.  I can't change it.  I have moved it to all the PCI slots and it keeps the 11 IRQ.  I can't change it from the PROPERTIES dialog box of the 1394 either.  I click on it on the RESOURCES tab but it won't change.

How can I change this IRQ?

I need this ASAP so I am giving this 250 points!

I just read an articlae on Microsoft's web site that stated I couldn't change the IRQ.  It is at http://support.microsoft.com/support/kb/articles/Q252/4/20.ASP

Given that, my card can't find my digital video camera.  I know it works, it did before.  Any suggestions as to how I can get it to work?  It is a Sony DCR-TRV11.  Sony's web site is no help.

Try to do this from SAFE mode.
Also, consider trying to manually assign IRQ's in the BIOS, or to turn of PNP OS in the BIOS.

Another option is to move the Other cards resources, leaving the  1394 IEEE host controller on IRQ 11.

I hope this helps !

I tried the 'Safe Mode', no change.  I tried the 'Bios', no change.

I took the IEEE 1394 card home and tried it with my computer using Win98.  Still no good.  I finally figured out my card was bad and bought a new one.  

Low and behold, it worked!  Wasted about 10 hours on this!

Now my problem, who do I give the points to?  SysExpert gave me some technical help, but it didn't work.  Stevenlewis may be a long lost distant cousin!

I guess I will put aside family loyalty and give it to SysExpert for his honest try for helping me!

Thanks for your help!

I'm sorry, I should have given you an 'A' because you did let me know the correct answer to my question, you can't change the IRQ's.

Wish I could change it!  Sorry.

Thanks anyway.
