the gpt-bios disklabel creates an additional partition with the
bios_grub flag set, which allows the bios to access the stages of grub
that don't fit in the mbr (see below). if your computer has uefi/efi
instead of bios then i believe you'd use straight-up gpt. (nb. lacking
such a computer, i have not tested this.)

the reasoning from /usr/share/fai/setup-storage/Sizes.pm:
# on gpt-bios we'll need an additional partition to store what doesn't fit
# in the MBR; this partition must be at the beginning, but it should be
# created at the very end such as not to invalidate indices of other
