How do I manually set IRQs in Windows 2000?
Posted on 2004-04-27
I have been experiencing crashes to desktop, hardware lockups, and insta-reboots while playing graphically intensive games. While getting support from the game vendor, it was pointed out that my USB is sharing IRQs with a number of other devices, and I should put USB, Video, and Sound all on their own IRQ.
If I go into device manager and attempt to modify the resources, it is greyed out, and I am unable to. I had read that in order to do so, I need to take windows out of ACPI mode. I changed from ACPI mode to 'Standard PC' but it still didn't work. I reformatted and selected "Standard PC" during the installation process of Windows 2000, and reinstalled my system in non-ACPI mode. Still, I am unable to change any IRQs.
Am I doing something wrong?
Here is the information on my settings:
Windows 2000 Professional SP4
A7V333 Motherboard with latest Bios.
VIA KT333 Chipset
Onboard C-Media Sound
Onboard VIA USB
AGP RADEON 9600 SERIES
1 PC/AT Enhanced PS/2 Keyboard (101/102-Key)
3 VIA USB Universal Host Controller
4 Network Everywhere Fast Ethernet Adapter(NC100 v2)
6 Standard floppy disk controller
8 System CMOS/real time clock
10 CMI8738/C3DX PCI Audio Device
10 VIA USB Enhanced Host Controller
11 RADEON 9600 SERIES
11 VIA USB Universal Host Controller
12 Microsoft PS/2 Mouse
13 Numeric data processor
14 Primary IDE Channel
15 Secondary IDE Channel
All PCI Slot IRQs are set to Auto.
No ISA IRQ Reservations.
USB Legacy: Auto
Onboard Serial 1: Disabled
Onboard Serial 2: Disabled
Onboard Parallel Port: Disabled
USB Function: Enabled
Plug & Play OS = No
Reset Configuration Data = No
Interrupt Mode: APIC
If I change Plug & Play OS to = Yes, it boots but one of my USB controllers, my network card, and sound card are all not working (I get a Code 10 error). Unable to fix it.
BIOS does not have Onboard Sound IRQ, Onboard USB IRQ, nor AGP IRQ settings.
I have already thought of disabling onboard USB and purchasing a PCI USB Card, but if possible I'd like to get everything on a separate IRQ with what I have already.
