When I do the triple wipe with diag, NVRAM, SafeStorage, and SSD it will let me set the machine ID and Asset number. But then it's locked unless you triple wipe again...
But..should be noted when I setup the GB server, the machine and asset ID of the server was already locked to 1. So both the server and clients machine ID and asset ID were both set to 1, yet it still worked for me. Not sure why but it did. The "client ID" on the game machine was set on 2 though. Perhaps because there's no IPC/UC or WAP involved, so the bonus server only cared about the client ID?
Now if I do a bonus server, it always is 1, and my other machine gets set at 2. Just because the PSR said so. lol
