i modded a 1.6b with an x3 chip. of course, i got the blank screen when i tried to flash it (flashbios 3.00). i put the chip in my 1.4 box, flashed it with the 1959 1.6 bios, and not when i try to power up the chip, the external led turns red and i get an error 07 (i dont have an hdd or dvd drive plugged in, if this is the problem).
