How do I change IRQ?

[theo.aku]

Hi I've just got myself a new sound card but it's fitted in on an IRQ channel with 2 other PCI devices and I think that this must be the reason that since installing it my PC is hanging on a black screen during start up for about 3 minutes, just after the windows splash screen.

Could someone please let me know how to change the IRQ settings (if this is indeed what I need to do) through the BIOS as I can't do it in windows (something to do with ACPI I beleive).

Thanks very much for your time.....

My settings look like this at the moment:

IRQ:
0 : System timer
1 : Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
4 : COM1
4 : Communications Port (COM1)
6 : Standard floppy disk controller
8 : System CMOS/real time clock
9 : Microsoft ACPI-Compliant System
10 : MPU-401 Compatible MIDI Device
12 : Microsoft PS/2 Port Mouse (IntelliPoint)
13 : Numeric data processor
14 : Primary IDE Channel
15 : Secondary IDE Channel
16 : MEDION RADEON 9600 TX
17 : CMI8738/C3DX PCI Audio Device <--- new sound card (a Trust SC-5250)
17 : Creatix V.9X DSP Data Fax Modem
17 : OHCI Compliant IEEE 1394 Host Controller
19 : MEDION (7134) WDM Video Capture
19 : SiS 900-Based PCI Fast Ethernet Adapter
20 : SiS 7001 PCI to USB Open Host Controller
21 : SiS 7001 PCI to USB Open Host Controller
22 : SiS 7001 PCI to USB Open Host Controller
23 : SiS PCI to USB Enhanced Host Controller

Usually, with the current Windows OSes, the easiest way to change the IRQ is to change the PCI slot.

Thanks, but unfortunately the setup I've got won't allow it. The Trust card effectively uses two slots and so there is no scope for moving it around.

There must be a way round this. I have empty IRQ slots sitting there so why isn't there a simple way of changing the IRQ. Perhaps someone knows a way of doing this in DOS?

"Windows XP cannot rebalance resources in the same way that Microsoft Windows 98 does. After PCI resources are set, they generally cannot be changed. If you change to an incorrect IRQ setting or I/O range for the bus that a device is on, Windows XP cannot compensate by rebalancing the resource that was assigned to that bus."
