Been playing around with this all day. I went out and bought an external DVD drive since the one in my XP laptop doesnt work any longer and I don't want to mess with the lady's Vista machine any longer. I tried using a Sony 16GB and an old TigerDirect 256MB drive for the install, but the mini wouldn't boot from the USB drives and load XP. So, I took the Sony drive back that I bought and purchase a 2GB Sandisk Cruzer Micro and a 16GB Sandisk Cruzer. So far, I've tried the method listed on mechdrew's page, but the mini would still not boot the USB drives, so now I'm waiting for TransMac to finish so I can give that a go. If this doesn't work, I guess I'll give the DVD drive method a go.
