- TITLE :STOP Message Appears After You Add Second SCSI Adapter
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:Buglist3.10
-
- --------------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- --------------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- After you add a second SCSI controller and install the Windows NT driver
- for that controller, a STOP message appears when you restart the computer.
-
- CAUSE
- =====
-
- Windows NT uses the ARC path specified in your BOOT.INI file to find the
- drive and partition containing the system files. If the path to the system
- drive changes without the BOOT.INI being updated, the STOP message appears
- when you restart the computer because Windows NT is unable to find its
- system files.
-
- In this situation, the path to the system drive has changed because it is
- dependent on the order that the SCSI drivers load so if you install a
- second SCSI driver that loads before the one currently on the system and if
- the Windows NT system files are on a SCSI hard drive connected to the
- original controller, the STOP message appears when you restart the
- computer.
-
- RESOLUTION
- ==========
-
- The immediate solution to avoid receiving this STOP message is to restart
- your computer to the Last Known Good configuration. After doing this, a
- permanent solution is to install the new SCSI driver, edit the BOOT.INI and
- change the ARC path BEFORE restarting the computer so it will be correct
- when you restart.
-
- There are usually two lines in the BOOT.INI that need to be changed,
- although there may be more if you have more than one installation of
- Windows NT. The first line that needs to be changed is in the [boot loader]
- section and looks something like the following:
-
- default=scsi(0)disk(0)rdisk(0)partition(1)\windows
-
- and the second line that needs to be changed is in the [operating systems]
- section and looks something like:
-
- scsi(0)disk(0)rdisk(0)partition(1)\windows="Windows NT Version 3.1"
- /SCSIORDINAL:0
-
- The one thing that all the lines that need to be changed have in common is
- scsi(0). This indicates which SCSI adapter is connected to the system
- drive. If you have already tried to install a second adapter and received
- this error, you need to change all references to scsi(0) to read scsi(1).
- After doing this, you can restart your computer. For more information on
- the contents of the BOOT.INI file and ARC paths, see page 160 of the
- Windows NT Advanced Server "Concepts and Planning Guide" or query on the
- following words in the Microsoft Knowledge Base:
-
- boot and arc
-
- After you make these changes and restart your computer, use Disk
- Administrator to save the new drive configuration to the Emergency Repair
- Disk.
-
- STATUS
- ======
-
- Microsoft has confirmed this to be a problem in Windows NT and Windows NT
- Advanced Server version 3.1. We are researching this problem and will post
- new information here in the Microsoft Knowledge Base as it becomes
- available.
