To specify a uniqueness ID during setup, the user must run the winnt or winnt32 command with the following parameter:
/UDF:ID[,database_filename]
where:
ID
is the uniqueness ID to use while installing Windows NT Workstation on this computer.
database_filename
is the filename, including the full path, of the UDF.
If both the uniqueness ID and the filename of the UDF are specified, the UDF is copied to the local drive during text-mode Setup, and is used during GUI Setup without user intervention. The UDF can have any legal filename.
If only the uniqueness ID is specified on the winnt or winnt32 command line, Setup requires a floppy disk with a UDF file named $Unique$.udf. This disk must be prepared by the administrator and made available to the user in advance. The user is prompted for this disk during GUI mode setup.
In either case, if the supplied UDF is corrupt or if Setup cannot locate the specified uniqueness ID in it, the user is prompted either to insert a floppy with the fixed UDF, or Cancel. If the user chooses Cancel, the values in the answer file will be used. These values might not be appropriate for the computer.
