@ mtnsrfr180: since you have the "starwars/tetris pack" it almost has to be a v1.4-1.5 xbox (use the version check in the tutorial section to confirm this) these boxes use a 256k bios so thats what you have to output it as in xbtool.
now for my question: i've been trying to get the hotswap working for a whole day now. first, i couldnt get the windows hdd drive to detect the drive at all. finally, (with some help) i realized i had to do the swap faster. now, hdd driver finds the xbox harddrive. BUT, whenever i try to "insert file" the program gives me an error (which I expected from the tutorial) and it crashes! (i tried pressing retry, ignore, and abort -- all caused the driver to crash.) i have windows xp with .net installed. can anyone help me please?
