Removing a driver

In the past, I had some success installing drivers for devices that weren't necessarily made for that OS. As a result, I forced the installation of Windows95 SCSI card drivers on a Windows2000 machine. My machine now will not boot when the SCSI card in in the machine, but when it isn't, it boots ok. I have since gotten drivers for W2000 for this card so I tried to install another set of drivers for this card, but that doesn't work either, same results, with card in machine, same blue screen, NOT BLUE SCREEN OF DEATH though. I proceeded, althouth not in SAFE mode, to delete all referenced to this device in the registry, after backing it up, but I am getting problems with inablity to delete the registry entries. I think that if I try to remove them when booted in Safe mode, it may work, but until I get a chance to try that, does anyone have any suggestions?

Did you try removing the entries from the registry when you were in normal mode without the SCSI card in? You may have more luck.

Does this show up in your device manager?

Finally, you may have to disable a service. What type of SCSI card is this?

Let me know.

I am unable to boot the machine with the card in therefore my attempts to remove the registry entries happened with the card out.

Second, I was not even able to boot in SAFE mode with the card in, same problem.

Third, the card does not show up in the device manager, otherwise I would have gone there first, to remove it.

The card is a SYMBIOS Logic card.

I hope this helps

What is the model of Symbios card? Is the card ISA or PCI? Did it come with another device (like a scanner or CD_R)?

When you are in Safe mode (with the card out), check the device manager there. A ghost of the card may show up.

Does the machine boot enough for the event log to be affected? If so, what does it say?

If not, you get a blue screen. The third line down it will have text. It may not make sense what it says, but I would like you to let me know what it says.

The Card is an ISA SYM20403 and came with an HP PhotoSmart Scanner.

In safe mode, I wasn't able to delete the registry entries either. There are entries in three locations,

HKEY_LOCAL_MACHINE
  SYSTEM
    controlset001
      enum
        isapnp
          SLI4161
            FFFFFFFF

The same structure except that the other two are at CONTROLSET002, and CURRENTCONTROLSET

Without the card in, I am able to boot, and the device doesn't show up.

The only Event item that is suspisous is a DCOM error. If this sounds like a potential, I can send you an image of the event view window.

The blue screen I get, is actually not the "blue screen of death", instead, here is what it says

*** STOP: 0x0000001E (0x00000005, 0x804A12FC, 0x00000000, 0x00000018)

KMODE_EXCEPTION_NOT_HANDLED
Address 804A12FC basse at 80400000 Date Stamp 3ad7ab60 ntoskrnl.exe

I hope this is helpful.

First of all, DCOM is short for Distributed Component Object Model. It may just state the obvious. Nonetheless we should view it. just let me know what it says exactly.

There have been some fixes out there that suggest that installing SP2 may help. Do you have SP2 on your machine?

You can try to disable all your other devices and reboot with the SCSI card in. We may be able to get it to run that way so it can be removed.

Let me know what happens. I will keep thinking about this situation.

I do have SP2 installed. I don't how know how to send an image with this system, but the message references some numeric value similar to that in the REGISTRY. I don't have it here with me, but I can get it to you tonight.

When you say to disable all other devices, which ones in particular? Again, keep in mind that with the Card installed, I got the same message in the blue screen even when booting in safe mode.

Please keep digging. I may be forced to reinstall the OS, which I don't necessarily want to do. Do you know of any good REGISTRY defragmentaion out there that will notify me of entries that I am not using?

Thanx
