If a reproducible STOP screen error appears when you run Windows NT Setup, you can usually debug the error either locally or remotely. Since Setup does not run in debug mode by default, you must first change the Setup configuration to allow debugging, and then run Setup again. How you then proceed depends upon whether the STOP screen occurs during the text portion or the Graphical User Interface (GUI) portion of Setup.
The STOP Screen Occurs While Booting the System from
the Setup Floppy Disk or During the Text Portion of SetupIf the STOP screen occurs while booting the system from the Setup floppy disk or during the text portion of Setup, and Setup was able to load enough of the operating system to invoke the debugger, you may be able to set up a debug session. To configure Setup for debugging when booting from the Setup floppy disks:
The STOP Screen Occurs During the Text
Portion of a WINNT /B or WINNT32 /B InstallationIf the STOP screen occurs during the text portion of a WINNT /B or WINNT32 /B installation, and your boot drive uses a File Allocation Table (FAT) partition, edit the Txtsetup.sif file on the root of drive C and change the OsLoadOptions = "/nodebug" entry to read:
OsLoadOptions = "/debug"
NOTE: You can also add other debug parameters to the string inside the quotes. For example:
OsLoadOptions = "/debug /debugport=com2 /baudrate=19200"
The STOP screen Occurs During the GUI Portion
of Setup and Your Boot Drive Uses a FAT PartitionIf the STOP screen occurs during the GUI portion of Setup and your boot drive uses a FAT partition, edit the Boot.ini file on drive C, and add the /debug switch to the correct line in the [operating systems] section of the Boot.ini file. To do this, boot from an MS-DOS floppy disk after the text portion of Setup completes, change the Boot.ini file, and then reboot from the hard disk.
The Boot.ini file entry you need to edit should look similar to the following:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows NT Server Version 3.5"
The /debug switch should be added after the text in quotation marks.
The STOP Screen Occurs During the GUI Portion
of Setup and Your Boot Drive Uses an NTFS PartitionIf your boot drive uses a Windows NT file system (NTFS) partition and you need to debug the GUI portion of Setup:
For additional information about the Boot.ini and its contents, query on the following words here in the Microsoft Knowledge Base:
