IRQ Question

AEP · Post by **AEP** » Sun Feb 16, 2003 1:09 pm

First off, I will give the specs on my machine:
Intel 845PEBT2 mobo
P4 2.4 533 bus
1 gig Samsung DDR 333
Radeon 7500 display adapter
Pulsar 2
WD 20 gig, IBM 80 gig hard discs
Sony CDRW + Floppy
Cubase SX + SFP 3.1c
Win XP Pro

By most accounts, the computer is running flawlessly. However, when I reboot, I am getting the

IRQ_NOT_LESS_OR_EQUAL

blue screen. This is a fresh install of XP (in standard PC HAL mode). The Pulsar card is in PCI slot 3, which I forced in the bios to use IRQ 5. I then disabled the USB controller that used that IRQ so the card would have it's own interrupt. I have disabled my parallel port, serial ports, and onboard Lan and Audio in the bios as well. This is a stand-alone machine created solely for audio. Every service that isn't absolutely necessary has been disabled through services.msc. The registry has been configured in such a fashion that all operations are kept in memory (although I have not yet switched to a static swap file for testing purposes). This blue screen hasn't affected my functionality at all, in fact so far it runs exceptionally well. I haven't gotten too far into the production because I just built the machine last week. However I would like to get to the bottom of this as soon as possible before it becomes a problem in the future.

Has anyone else experienced this? Should I leave the PCI slot 3 IRQ setting to auto instead of forcing it to use IRQ 5? Any suggestions would be greatly appreciated...

IRQ_NOT_LESS_OR_EQUAL =Incompatible driver

means the board is not happy sharing it's irq with something else.

This is the driver from creamware! The one that installs with 3.1c.

If I look in my device manager and view "resources by type", it only lists the soundcard as using IRQ 5.

It was my Oxygen 8! As soon as I uninstalled it and used the newest driver, no more blue screens. This was a problem with the old driver and XP. I remembered this in the 11th hour from when we first installed the driver on a friend's XP machine.

As usual, the problem turns out to be related to thick-headedness......

Thanks for the help....
