yah, i have a tommy to, and i know its not gonna read slayers.
what i did is, i used what softmodders use to build their harddrives.
since you already have slayers, you can use the C and E retial from that, and stick the evoxdash.xbe in the C folder.
once you get xboxhdm all set up, you can build the harddrive with retial and the evoxdash.xbe in C.
having evoxdash.xbe in there will allow you ftp acsess, and youll be able to set your xbox up as you want it.
read up on xboxhdm for dummies in the non-modchip forums. you dont need the eeprom.bin since you dont have a softmod.
