Minimally setup Messiah 2 to test
I am having a problem installin Messiah 2 v1.3 chip. I soldered all the wires and couldn't boot any backups. At this point I would like to find out if it's the chip is defective or not.
I have another ps2 to test the chip. How can I minimally setup Messiah 2 to test it? I remember seeing it somewhere that I need to only connect 3.4V, GND, RESET and SCEX wires to test PSX1 backups. Is this true? Do also I need to connect BIOS wires (M-V, W and R) for PSX1 backups only?
Thanks very much in advance.
