Scanner freezes Windows XP

windows boots ok w/o the scanner connected? do you have correct termination and unique scsi id on scanner. do you have latest driver for scsi ctrl. can you get 'behind' the xp logo screen using tab or esc to see what error if any is occuring. anything in the system event log? will it boot in Safe mode

Yes, boots fine with scanner powered off. Using a terminator on the scanner itself and using auto termination for the card. SCSI ids are 6 and 7. System seems to be hanging on drivers/mup.sys.

Do you have any other SCSI devices installed or an On Board SCSI Controller?

As you can boot with the scanner turned off what happens with the computer running and you turn on the scanner?

If there are no other SCSI devices present and no Onboard SCSI Controller my first impression would be a hardware incompatibility with Windows XP as I can't find that model listed on the Panasonic site I'm only guessing here but it sounds very much like a Device Conflict on a SCSI channel and from your description it sounds as if it's the scanners address.

If you have an On Board SCSI Controller you'll need to run this scanner off that even if it means using an adapter for the lead. Just a side note here every SATA controller appears to Windows as a SCSI Mass Storage Device so it's possible that you have a hardware conflict with something already installed in this computer.

Generally with everything else being equal the SCSI Controller is 0 or 1 and if you have a terminator involved you shouldn't be able to use the device 7 as a setting and have it work. If you try changing your scanners SCSI address it may fix your problem but if there are other SCSI units involved there may be a conflict arising that is stopping the system from working.

If this is the case and you need to retain the existing SCSI devices you'll need to upgrade your SCSI to PCI Card to one of the SCSI Ultra Wide types that allows more than 7 devices to be connected.

Two possible things to check out...
1) Can you boot in safe mode?
2) Try attaching the scanner after booting

After performing either of the above two, then install the proper drivers for the scanner.

The problem is being caused by your system trying to access the scanner with incorrect or imporper drivers, and MUP must wait for those drivers to initialize before it can proceed and permit the machine to boot.

If neither of the above works, it is possible that you have a hardware problem with the SCSI card or the interface on the scanner.

If I turn the scanner on after booting, then the RTIV software says no scanner found. I will try changing the SCSI ids. I don't think the SCSI card is bad because it shows the device correctly before Windows begins to load.

adaptec sez this known problem with some motherboards are recommend updating the bios and drivers for your motherboard.
they also suggest using the correct version of aspidos driver (if u use one) and that you check to see if the 2940 is in a bus mastering slot. i would also check at panasonic website to be sure that is a compatible adapter and that you don't need to be running in non-wide mode or something...

Panasonic website doesn't have much info. I realize it doesn't list it as compatible with WinXP, but I was able to set up on Win2003 server which is also listed as not compatible. What is a bus mastering slot and how do I identify it? I have double checked the ASPI driver and it is correct. I will try a bios update next.

i meant compatible with the scanner, but you are right, that is irrelevant...the bios updates sounds promising. a bus mastering slot is a particular slot on the motherboard that is, well, the bus master. dunno actually. assume it gets some kind of precidence on the pci bus...
the symptom of it being detected but hanging windows at boot is one that they talk about at the adaptec kb. a resource conflict maybe due to inappropriate handling of the slot during pnp (i think) by your motherboard bios. which slot is the bm depends on your motherboard. in the day, i used to use as a rule of thumb the one closest to the power supply but who knows? just try all the slots starting with the ones on the 'ends'...if your bios doesn't say anything about turning bm on under PCI slots then don't worry about that...you might try hih

Thank you thank you. It is working now. Funny how we forget the simple things like changing slots.
