Two questions came up while thinking about the replacing:
QUESTION 1:
Is it right that I can just take out the Lite from the pin header and add the Pro without doing any further soldering (using the wires which were already soldered for the lite).
QUESTION 2:
Can I just run EVOX from a CD-RW, then upload BIOS to xbox (connecting to PC using FTP), flashing BIOS using evox dashboard?
