The script will stop and ask you to hit enter to continue to load SCSI drivers, it then asked me if I wanted it to probe for SCSI drivers: [n], I took the default [n]o and hit enter.  Next, it asked what partition contains your NT installation, I took the default again, in this case [/dev/hda2] and hit enter.  Then it asked:  what is the full path to the registry directory, again select the default [windows\system32\config].  Next came the question, which hives (files) do you want to edit (leave default for password setting, separate multiple names with spaces), the default was [sam system security], I chose to type software and hit enter.

I then chose option 9 - registry editor.

A ? will get you a list of commands that are available, I used ls which appears to be equivalent to a DOS dir command... cd to change directories... cat to print the value of a key... and ed to change the value of a key.  

For instance (this is from memory, not notes... sorry) at the prompt [1020], type cd Microsoft and hit enter, then cd Windows NT and hit enter, then cd CurrentVersion and hit enter, finally cd Winlogon and hit enter (case is important).  

Maybe you could just type one cd Microsoft/Windows NT/CurrentVersion/Winlogon and hit enter... I don't know.  But it seems to be the registry equivalent of
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
 
At that point I typed cat Userinit and lo and behold, up came
C:\WINDOWS\System32\wsaupdater.exe... I don't know what company replaced userinit.exe with this entry, but I don't think I like them.  At any rate I typed ed Userinit and at the prompt [C:\Windows\System32\wsaupdater.exe] I typed C:\Windows\System32\userinit.exe and hit enter.

Then q to quit (you will be asked if there is something to save), q to keep quitting and y when it asks if you're sure you want to write the changes (careful, careful... good luck).  The program then dumped me out to a # prompt and said I could rerun the script if I typed a space followed by sh /script/main.rc

I removed the cdrom from the drive and rebooted to Windows XP, no problems.
