Install XP from flash drive

I know there's a good way to do this, but the guides I found on google don't work, and I couldn't find this in search. Can someone link me to a good guide or tell me how to do this? I want to install XP SP3 onto an Asus netbook.

 

To bad the mods arrange everything so its impossible to find, links in my sig.

 

I suppose that's why. I can never find anything with search. I hope this works! I'll rep you when I'm finished.
