But the hardware and the ROM was the same in the US, weren't they?

That's what I mean - what is the "default" (not set by Workbench). If there is no code for setting the mode to either PAL or NTSC and both ROM and hardware were shared between PAL and NTSC countries then how did it decide which mode to use for the Guru?
