Problem installing Tablet PC Edition

Hi everyone, I have a problem that dont find solve and Im :twisted: for that problem that is simple! Ok, here we go, first of all, I have a Gateway with ability of Tablet PC, the computer begin to run with problems and I decide to make a slipstreaming CD with my drivers (I need the SATA drivers for install XP when I boot) and also I add the Service Pack 2, all this using nLite (the CD source are a VLK installation). After all, I formatted the partition 1 and re-installed with the CD that I make and everything is fine. But, next I decide to have Tablet PC edition again, and see that the CD that I make have the components for Tablet PC. Now I want to install this components, and I read that this components is the "Tablet PC Edition". But with the Key that I use install just XP PRO. I read a lot of change setupp.ini, change unattended.txt and I use the OEM key in the bottom of the laptop and dont work. What I need to do? I read that if I put the OEMBIOS files in the CD and put the OEM of the laptop this work, but for me not! Also I read all about OEMScan, but I dont understand, I use this software in my laptop and this tell me that MATCHED with Gateway and Copy the files to system32/dllcache/ but what I need to do?

I really want to install the Tablet PC components that is in the CD, also I have the components in a Backup Harddisk, but I dont have the I386 original folder.

I just have the Recovery partition in D:\ but it dont have the OEMBIOS, setupp.ini and winnt.sif. What I need to do?
