sysinst and gpt

[Christian Lerrahn <lists%penpal4u.net@localhost>]

Hi,
I've been trying to install NetBSD 5.1.1 to a 3TB hard drive but
sysinit always throws an error about the MBR not matching up and the
drive will always be considered a 2TB drive. Obviously, sysinit fails
to recognise the GPT partitioning and is unable to install to such a
drive.

I'm not fussed about booting because I'll probably have grub on the
drive, anyway. According to what I found on the web, NetBSD is generally
able to handle gpt partitioned drives, so how do I install to such a
drive.

I can boot from a CD but also have access to the system via a FreeBSD
or a Linux system.

TIA,
Christian
