Do we runt he Netbook Installer on the Installation Flash drive or on the Hard drive of the Computer after we install??

I've ran the NetBookInstaller only AFTER I had installed Snow Leopard, and on the Hard Drive in which I installed.
On the Flash drive, you only need to restore your Snow Leopard disk and then patch it using NetBookMaker, nothing else.

Oh, sorry for not warning you, but this "unsupported device" thing always shows up, the other tutorials only say to ignore it and still run.

This method should work with any external HD drive or 8GB+ Flash drive.

trying it now

is there any kexts i need to install to get it to work??

That's what I'm exactly figuring out.
I'm a little busy here with some work, that's why I'm not trying at the moment, but I can show you some stuff people used when installing Leopard on NB200:

This is the Essential Package by wingzero with a lot of stuff we needed to keep Leopard running good.

You may also want to read the post I did a few weeks ago talking about the packages, Leopard tutorial and some other stuff.

If you have any success, please tell and share with us.

i tried to install doing what you said and i either get a kernal panic or just a white screen

Are you sure that you're following it correctly? Because it worked perfectly on my Toshiba NB200... I had Windows XP on it before installing, so it wasn't an update, it was a fresh install.

Your netbook does conclude the installation process? Or it crashes/freezes before or during?

i have the flash drive fully patched now and it doesnt even recognize it in the boot menu. so i am not sure what i am doing wrong.

wait i had it as GUID not MBR so ima try this again and let you know

didnt't work doesnt notice it when i start it up
