You can install an OEM unattended at least somewhat. I can't figure out how to automatically get out of scandisk without hitting ok or the **** plug & play monitor at the end. BUT the eula can be passed by.

adding:
HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion","ProductId",,12345-OEM-1234567-12345
HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion","ProductKey",,ABCDE-FGHIJ-KLMNO-PQRST-UVWXY
HKLM,"Software\Microsoft\Windows\CurrentVersion","RegisteredOwner",,User
HKLM,"Software\Microsoft\Windows\CurrentVersion","RegisteredOrganization",,none
somewhere under the [install] section in your batch.inf bypasses that.
I don't feel like explaining it detailed like tho'. But this should help.
http://www.msfn.org/board/index.php?showtopic=21230I've also figured out how to add some settings automatically to msdos.sys. And am supposed to be able to do the same for autoexec.bat, config.sys, and win.ini I think.
