3.4 SGI / MIPS Firmware

The SGI / MIPS firmware allows booting from special boot files, which are managed by the partition table. In Parted, these boot files are treated as logical partitions inside an extended partition.

For example:

Disk label type: mips
Minor    Start       End     Type      Filesystem  Name        Flags
9          0.000      2.732  extended
17         0.002      0.002  logical               sgilabel
18         0.003      1.162  logical               symmon
19         1.404      1.670  logical               sash
1          2.732   8555.212  primary   xfs                     root
2       8555.213   8682.270  primary                           swap

Partition 9 is the extended partition (volume header in SGI/MIPS terminology) where the boot files may lie. Partitions 17, 18 and 19 are the boot files. There names can be manipulated with parted's name command. Partitions 1 and 2 are normal partitions. They can't have names.

Note that Linux doesn't see the boot files as partitions (maybe it should?). So /dev/hda17 doesn't exist in Linux. You should use dvhtool(8) to manipulate boot files.
