Once you have everything on ur desktop, install iprep, go to where its installed to and drag and drop the ixml file into its resources folder and it will ask you to replace, choose yes. Now iprep is ready. Load up your 1.6 FW, choose your sata port, for mine I had to swith it to IDE based, drop down the menu and you should see your port. choose your device, Obviosly the stick, Tick box to format and make bootable, the other box for batch files shud already be checked. Now prep the stck and your good to go.
Good luck !

The ixml def file is underneath iprep mate
