# Default block device setup for PPC
# ----------------------------------
#
# Details (extracted from [1])
#
# Power Firmware (OFW) scans chosen (nvram value boot-device) device,
# for either PReP* partition or vfat.
#
# PReP is raw and small (8M max) partition which caries only stage1
# binary.
# msdos partition table:
# - PReP partition have 0x41 type (must be active)
# - PReP partition must have boot flag set
