\-append_partition, then mbr_force_bootable="on" causes a bootflag like it
would do with a bootable MBR.

\fBgpt_iso_bootable=\fRon causes bit 2 of the GPT partition flags to be
set for the ISO 9660 partition if such a GPT partition emerges. This bit is
specified as "Legacy BIOS bootable" but its true significance is unclear.
Some GPT\-aware BIOS might want to see it in some partition. Mode "off"
revokes this setting.
.br
\fBgpt_iso_not_ro=\fRon causes bit 60 of the GPT partition flags to be not
set for the ISO 9660 partition if such a GPT partition emerges. This bit is
specified as "Read\-only" and thus appropriate. But it is unusual in GPT disk
partitions. Mode "off" revokes this setting and causes the read\-only bit to be
set.

\fBmips_path=\fRiso_rr_path declares a data file in the image to be a
MIPS Big Endian boot file and causes production of a MIPS Big Endian Volume
Header. This is mutually exclusive with production of other boot blocks
