DRIVER_IRQL_NOT_LESS_OR_EQUAL

[Dave]

I intermittently get BSOD's on Windows 2000 Professional
with the following error:

*** STOP: 0x000000D1
(0x00000000,0x00000002,0x00000000,0x00000000)
DRIVER_IRQL_NOT_LESS_OR_EQUAL

this has happened while running any number of different
applications. Can anyone tell me how to systematically
track this down?

Stop D1 can be caused by any driver issue. Many times the only way to find
the driver is to read dump in a debugger. You can also try turning on
Driver Verifier to see if it flags the driver. If so you will get a
different stop error and it will list the problem driver.

Verifier /flags 9 /all

How do you turn on "Driver Verifier"?

I'm not an expert here but thought that I'd add my experience.

I recently had the same problem and spent many days trying to find the
source. It was suggested to me that an interrupt conflict was causing the
problem. It was further suggested to check to see if any PCI boards were
sharing an interrupt. If so, it was suggested that I move one of the PCI
boards to another slot so that it would not share the IRQ. (my modem & sound
card were sharing IRQ 17)

I was resistant to the suggestion because Win2000 and the PCI bus are
designed to share IRQs. Nonetheless, out of desperation, I moved one of the
boards to eliminate the sharing - and - Voila! It worked!!!

I don't understand it but it worked.

Good Luck.
