that's true, all you do need to do is insert a floppy with the winnt.sif file on it for any windows XP or 2000 OS however, to install all the other common software that takes all the time is what takes forever anyway, so why not include that as well? basically, I put the follow lines in my cmdlines.txt file in the $OEM$ folder: [COMMANDS] "a:\useraccounts.cmd" then I put my user accounts.cmd, autologin.reg, winnt.sif, and my batch files on the floppy just don't forget to change the line in the winnt.sif file to the name/location of your batch file to install windows I've attached a zip file that contains all the files on my floppy so you can use them for an example Nice thing about this is, you can edit and modify installations such as rem out a line of a particular installation doesn't require all of your software that you are capable of installing
