Yes. If the drives are > 2TB you lose. BIOS is not for you... Unless you make special partitions that are in the first 2TB of the drive and only boot off of those. Also, if the drives are 4k, you likely lose, though it's hit or miss. Those are the hard limits of the BIOS ABI.
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 Miroslav Lachman
