A few quick shot questions for you brainy fellows:

1. Internal HD installing - I know they use 2.5" SATA HD's & physically how to put it in, but how do I install the PS3 OS on it (if it needs installing)?

2. Partitioning the HD & installing another OS - An option in the system tools, does this mean I can duel boot my PS3 with different OS's??

-------------------

I'm big on tweating and juicing up my PS3, I love the networking side of how it works & have got WMP file sharing on it to my PC.. and the little guy even has its own router and its own IP addy. But now i want to get inside the thing and install all this hardware yummy
