IRQ Problems

[FourWheelDrift]

Hi

After a house move I have set my PC up, I couldn't remember which USB port I had plugged a steering wheel into so chose one of the 2 on the back of my PC. This seems to have thrown a major IRQ error up as my DVD drive no longer works. (It's powered up but recognises no disc), I have checked the System Information and under Problem devices it says "IRQ holder for PCI steering PCI\IRQHOLDER\60 Error 22". I seem to have an IRQ Holder for PCI Steering on IRQ ports 9, 10 and 11. My DVD player is set for IRQ 10. I have tried to reassign IRQ's from the Device manager but Windows will not allow IRQ's to be changed. I have no idea how to delete an IRQ listing (I want to get rid of the PCI Steering from IRQ 10) to see if this will get my DVD working again.

Or is there something else that needs to be done. Stupidly enough the first thing I did was to remove the PCI Steering software (uninstalling the drivers) thinking that with no PCI steering device installed it might sort itself out......nope.

Anyone have a idea on this one???

thanks

You've got either a SCSI DVD player or a RAID IDE controller? That's about the only way a DVD drive can get on interrupt 10. And to correct what you are saying, the DVD is not on interrupt 10, the IDE or SCSI controller that the DVDRom is connected to is on interrupt 10. If you are using a RAID IDE controller, I would try moving the DVDRom onto the secondary port so that it is using interrupt 15.

It's not the wrong usb port that's messing things up, I can almost guarantee that both ports are using the same interrupt. Sounds just like a driver problem. If I were in your situation I would start up Windows in safe mode, and in the device manager I would go through and remove every driver under the system devices heading. Reboot and Windows should redetect them automatically. If you're running Win98 there should be no problem recognizing the devices again, and I assume you are because you're able to use the usb port.

And also, interrupt changes are made in the cmos setup, not within Windows.

Hi Dakota81

I had a go at what you suggested, no luck though. My DVD drive is not recognised in Windows even though the device manager says it is working properly. Do you think it could be something as simple as the DVD drive no longer working (broken in some way?) in other words a new drive needed?

Thanks

Make a bootable disk and load the dos driver for the drive and MSCDEX. If the drive works then, there is a software or driver problem with Windows. If the drive does not work with the boot disk then it's a hardware problem. This is a good way to just get in an separate out what the problem is.
