Thank you for your feedback, I would be very interested in your translated version. Ok, I may be on completely the wrong track with this one. I have downloaded a dos boot disk with network from Bart's Network Boot Disks My plan was to boot to dos, connect to the distibution point by mapping a drive (eventually to be automated) and then run setup (from dos). This would allow me to install onto a new harddrive. I go to the mapped drive, run my batch file (which works from windows - 'computername' assigns to the computer the name I give it)... setupxp computername The error I get is.... invalid switch - /S This program cannot be run in DOS mode. If I choose the alternative autoname version I just get... This program cannot be run in DOS mode. To be clear, this is the automatic batch file created by the setupmgr program.... @rem SetupMgrTag @echo off rem rem This is a SAMPLE batch script generated by Setup Manager. rem If this script is moved from the location where it was generated, it may have to be modified. rem set AnswerFile=z:\unattend.txt set SetupFiles=z:\i386 z:\i386\winnt32 /s:%SetupFiles% /unattend:%AnswerFile% /copysource:lang Is there a command line version of the setup program that I should be running instead?
