Force IRQ for XP

Visibleman · 10-02-2004, 19:57

hi all,
i recently got a new machine which im trying to go over to, and i installed one of my soundcards (Digidesign Digi 001). The installation goes fine, but windows XP seems to always put it on a virtual (shared?) IRQ - is this correct?, since there are only 15 physical IRQ's and XP has shoved it on 19. However, having the card on a shared IRQ is causing a lack of data to soundcard and external break out box and thus im hearing a 'stuttering effect' - i could increase the buffer, but this only resolves it abit, plus it beats the objective having a 600 quid music production soundcard

Basically, is there away of forcing XP to change the IRQ?

Under the hardware properties, the 'Use Automatically Settings' is disabled and therefore i cant deselect it and force the IRQ i want. Ive tried doing it under the bios (of the Asus A7n8x-deluxe mobo) but i can only 'revserve' a IRQ slot, but cannot force it to a certain piece of hardware

Apparently there is an option to 'reset the configuration data' under the pci/isa menu in the bios. However, this isnt present and ive flashed the bios to the newest bios update but still no joy

I have also disabled everything in the bios that im not using, like modem bridge, serial ports, usb for keyboard etc but it still has done anything.
Also, ive tried switching the soundcard to different pci slots (since im not using any, apart from the agp slot) but XP keeps putting it on virtual IRQ's

However, i havnt tried the card in 3 of the slots (there are 5 pci slots in all) - 1 is right next to the graphics card and it wouldnt fit, but also all three of pic slots i havnt tried are 'shared' (according to the manual). The two i have tried state that they are 'used' pci slots - havnt got a clue what 'shared' and 'used' pci slots.

Anyways hope some can help me, because im at my wits end and if i cant get the soundcard to work, then its back to my xp1700+

cheers all,
Dom

p.s - machine specs are:
xp3000
A7N8x - Deluxe mobo
512mb DDR300
Geforce FX5200
Crappy XP Prof. (have to use it, because SNDcard doesnt work on anything else apart from 98)

Have you tried running the built in troubleshooter from the cards properties in the device manager?
