Hi men,

FreeBSD 7.1 supports booting from GPT partitions.
I want to know more about it.

Without GPT, MBR reads the Disk Partition Table(DPT), and read the
first sector of the
boot partition.
If map the bootable GPT-partition in to DPT in MBR, then the boot code
in MBR reads
this partition, just like it's a normal partition. What else need to
do to support booting
from GPT partition?

Thanks,
Wu
