IRQ's and dropped frames

Have set up two monitors and reckon they are the Bee's Nee's, so much more room to put things.
BUT Win 2k of course insists on putting everything on IRQ 11 and now I get dropped frames with capture. I can set up a special hardware profile for capturing to disable the second monitor and other things I suppose, but it's a bit of a pain re-booting all the time.
Has anyone played around with re-asigning IRQ's in 2k?
Thanks, Brian.

This is the way of the future, so despite some hardware manufacturer's claims, your whole system *should* be able to function just fine on a single IRQ. After all, DV's 3.5M/s is so slow there's no reasonable excuse for it *not* to work.

Of course, to install the 'Standard PC' HAL you'll likely have to format and reinstall the OS and that by itself may get things working.

I agree, it should work, but with seven things on IRQ 11 the dropped frames started to happen. They were incidently, MS acpi system, G Force 2 video, the second G Force2, VIA USB HOST, VIA on board audio, CMD PCI UDMA controller and the TI Firewire card. My solution since the last post was to partition another 4 gig section and load a new W2k as a "Standard PC" and only put programs on it associated with editing.
What a difference!!! the audio is now as clean as a whistle, the video preview much smoother and never a dropped frame even with capture preview enabled and playing Solitaire during a ten min test.
The IRQ list now only has the firewire and USB on the same IRQ and still has both monitors on another one but one would hardly want to use the scanner when capturing and the monitors don't seem to mind.
Using the little disk speed checker from the DV Raptor site my transfer rate to a 40 gig 5400 Seagate on the CMD PCI card is 27 Meg.and the others only slightly lowwer.
I will keep the modem disabled and not install anti-virus or other b'ground stuff on this drive and do my normal work on the other boot. Have to tidy it up a bit but expect to wind up with two 4 gig partitions on a Seagate ATA33 8 gig as the system drives.
Incidently I am using a PIII 1Gig with 780Meg of ram.
Any comments? Brian.
