Is there a reason that you don't want to use BartPE based CD with WinTech?
Process of creating such bootable CD is described in EEPC product documentation.
I should add, there's a script and post on my site on how to use Windows AKI to set up a proper WinPE cd.
The only thing missing will be the appropriate SATA etc drivers for your laptops, but you can get around that by switching the BIOS into "compatibility mode" prior to booting off your CD/USB stick.
I personally have a build with a whole bunch of the common drivers in it, but as usual, redistribution by McAfee is on twitchy legal grounds.
