Hook it up to target manager, connect and boot. When it boots a message will show up in the console output. For an example here's mine rsx: b01 500/650 vpe:ff shd:3f [G1A828000:1:2:18:a:a:3:9:1][39:2:0:0:1:2:1][0:0:0]
Any other ways? Preferably one that requires minimal setup, I have a local contact interested in selling me one, but I need to find the rsx version
No other easy way because this is the easiest way. You hook up a lan cable from the DEVLAN to a switch/router and connect to it with TM running on a PC. That's your best bet unless you want to take a gamble
