XG2758 POST boot codes?
checked the docs and official PDF but didn't find anything in particular. Customer has an older XG2758 device that he tried switching back on but doesn't seem to work/boot and only shows BIOS post code F8 on MB. Any doc what F8 stands for on that particular build?
(0x) F8 on the internal display (port 80) is the expected last thing displayed when it boots correctly.
Check the second virtual comport for diagnostic info, that should always display something. The port 80 output is also shown there together with thermal values and CPU error values.
