Hi, I've got a small PC that currently has two disks: The first one is 1 TB with a standard MBR, used to boot FreeBSD, and the second one is 3 TB with GPT, used as data disk for FreeBSD (the BIOS doesn't have to care about this one at all because it's not used for booting). Now I would like to replace the first disk with a 3 TB one, too. However, will I be able to boot from it? The PC is not exactly a new one (ASRock A330GC with Atom 330 processor, a few years old) and has a standard BIOS (dated 07/16/2009). I understand that I will have to use GPT in order to be able to use the full capacity of 3 TB, and that I will have to install a pmbr to enable the BIOS to detect the disk as bootable. Is this correct? Will that work? (Assuming that the boot partition will have to be within the first 2 TB of the drive, of course.) If everything else fails, I'd consider using an additional drive for booting, probably an SSD. But I'd like to avoid this if possible. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
