It is not always that simple math. As I wrote in my previous reply, my 
pool was unbootable in one machine but boots fine in the other. Both 
were Intel based amd64 with BIOS, not EFI. I think there are some buggy 
BIOSes where it cannot boot even on smaller pools than 2TB. (or maybe 
some improved BIOSes supporting larger boundaries than 2TB? I don't know 
in what exact position bootloader / kernel was on my 4TB pool)

Kind regards
