IRQ ALLOCATIONS, AUTO OR MANUAL?

[GFBeranek]

On my NT system I disabled the USB ports, the parralle port and just about everything I could in order to free up IRQs. In the CMOS setup (AMI, super P6DGE) I can manually asign IRQS to the PCI ports by turnning off AUTO in the PCI setup. Currently some of my hardward is sharing IRQs. Most of the time without problem. Watson does poke up once in a while and tells me there is. Rarely though considering the amount of time I spend video editing on the machine. I know I have some free IRQs, but I'm not sure which ones they are
In Win NT Diagnostics/resourses/ device/ there is nothing shown using IRQs 2,3,4,5,7,8,13. My five PCI cards are using IRQs 9,10,11. I would like to break up the IRQ sharing if I could. Is this a smart or dumb thing to do?

RESOURSES

01 msi8042 isa Mouse?
06 floppy isa floppy
09 pcdvKml pci Canopus DV Rex M1 video capture card/codec slot 5
10 pcdRTUK pci sister card to the Rex M1 slot 4
10 sbpcint4 pci sound card slot 1
11 2930u2 pci scsi controller card slot 3
11 Xplode pci Canopus graphics accelerater card agp
12 msi8042 isa Keyboard?
14 atapi isa CD Rom ?
15 atapi isa Primary drive c/d partition

Now what can I do with the above? The system is for video editing only. No printers, usb, network, modem or anything else. Also, can I gain anything by disabling un-needed services. I'm trying to make this a purely dedicated system, rock solid and stable. Or is there such a thing?

I wouldn't mess with the interupts if they are working properly, the hardware vendors know which interupts they can use for their devices without problems. USB is not available for Win NT, (at least not NT 4). NT was designed to be a multi-tasking system, so unless you do not have memory dumps, and the system restarts, everything is fine.

Interupt 3 is most of the time used by the serial port.

You can safely move your SoudBlaster to IRQ 5, it is SB default IRQ.

The rest I should say is trail and error depending on your hardware.

Sharing aint bad, it all depends on your system.

Hope this helps
