What's the Sparrow Driver?

If I look at my Event Viewer it says that the driver was configured with an incorrect interrupt for SCSI port 2.  Is this because I don't have my Epson scanner turned on or is there another problem that I'm not aware of?

Sparrow driver is the driver for your SCSI-Adapter.
Does the problem only occurs with the scanner turned off?
What else is installed in your computer?
What scsi-card do you have?

I don't have the scanner connected to the machine and to be honest I haven't hooked it up.  I've got too much other stuff connected right now to even get near the computer with the scanner.  It's an Adaptec 1500 series card but I'm not sure of the exact model.

I think these type of adapter has no auto-termination. So you must connect the scanner or a external Terminator. The scanner has to be turned on to terminate. You can switch off termination of the scanner and connect the external terminator to the 2nd SCSI-port of the scanner (if there is any).

I've got a Pro Audio Studio sound card and an Iomega adapter card for a Ditto 3200 tape drive also installed.  The computer itself is a Dell XPS-P100C with 80 MB RAM, NEC 4x CD-ROM, Teac FD505 dual floppy drive, #9 GXE64 video card and two hard drives; Maxtor 3.5 GB and Seagate 1.0 GB, both are IDE.

So the scanner is your only SCSI device?
The AH15xx adapter is only for the scanner?
Does the problem occur when the scanner is online?
For this Adapter I think you must manually assign a IRQ. Make sure that no one else is using this IRQ. If you have PnP or a PCI Motherboard you can set IRQ used by ISA (or similar) in the BIOS-Setup.
Which IRQ are you using for scsi, dito and Soundcard?
in NT use  %SystemRoot%\system32\winmsd.exe  to determine which IRQ's are in use.

The SPARROW driver looks only to IRQ 11 unless the registry is manually altered.

To over ride the hard coded IRQ 11 in SPARROW.SYS:

1. Back up your registry

2. Unless you have a lot of spare time and all your NT 4 tools, back it up again.

3. Get Q102991 from the Knowledge Base; even though it refers to NT 3.1, the principle seems to be the same.

4. Using REGEDIT add "Parameters" as a subkey under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Sparrow

5. Add "Device0" as a subkey under "Parameters," just established.  If the SCSI card is not the only SCSI card in the system, you may have to change the "0" to "1" or whatever.

6. Add as a string value under "Device0" "DriverParameter"

7. Set the value of DriverParameter to "IRQ=12" (no quotes needed; REGEDIT will add them automatically).  My card's IRQ was 12; yours may differ and you must set the IRQ to the actual IRQ.

8. Reboot & check the event log and NT diagnostics to make sure that the new IRQ is in place.  You shouldn't see any more Error 13 entries in the log, and the "Resources" tab in NT diagnostics should show the correct IRQ for the card.

Best wishes to all.
