Sharing IRQs

I've read many times, that a CW card should not share it's IRQ with other devices.
Well, I looked at MS System Information and what's the result?
IRQ 0 System timer
IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
IRQ 3 Microsoft ACPI-Compliant System
IRQ 3 RADEON 7000 / RADEON VE
IRQ 3 VIA Rev 5 or later USB Universal Host Controller
IRQ 3 VIA Rev 5 or later USB Universal Host Controller
IRQ 3 Realtek RTL8139 Family PCI Fast Ethernet NIC
IRQ 3 Creamware Scope
IRQ 3 HPT370 UDMA/ATA100 RAID Controller
IRQ 6 Standard floppy disk controller
IRQ 8 System CMOS/real time clock
IRQ 13 Numeric data processor
IRQ 14 Primary IDE Channel
IRQ 15 Secondary IDE Channel

I see IRQ3 is pretty crowded. But what can I do for it? Radeon is AGP, and Scope is in the only PCI slot that it fits (well, badly) due to MoBo design...

hi spoimala,
i don't know your mobo, but at least in mine (tusl2-c) i can set fixed irq's for pci slots. where are irq's 9 or 5 ? they usually are used for audio....
what mobo and system do you have?
are you confortable with bios settings?
if you use xp with acpi mode i can't help, ask atOmic, he knows, but if you use xp with standard pc mode or 98se or millennium, you can do some things....

let me know...ciao.

My mobo is some ABIT -crap.. KT7-RAID or something.
I have XP in ACPI mode.

if it is working dont worry about it.

abit has an extremely confusing way of assigning the IRQs to the slots.

notice that IRQ 5 and 7 are not even being used by anything. if you could force scope to IRQ5 or 7 then it would be nice.

Oh yes, I didn't mention, it IS NOT working.
Awful crackle and pops all the time.. even with just playing an MP3!
ASIO freezes from time to time, and I even have Blue Screens Of Death!
Oh, and some constant noise and hiss is outputted... and this noise varies according to mouse movement. And disappers totally when I left click and scroll something.
