"Interrupt Request 09 not Available" Conflict in Windows 2000
In the Windows 2000 Device Manager properties for the P-Series driver, you might see a conflict (see below) indicating the IRQ that the P-Series driver is using is not available.
This appears to be a problem in the way that the P-Series driver reports it usage of the assigned IRQ to Windows 2000.
This is a known issue and does not effect the operation of the P-Series drivers and hardware.
