Disk Volume Header
From LinuxMIPS
On a SGI's ARCS systems all disks (even CD) must have a IRIX volume header vh(7M) and partitions. A typical IRIX bootable volume consists of the following partitions:
| Partition # | Use |
|---|---|
| 0 | Root Filesystem partition |
| 1 | Swap partition |
| 7 | Volume Body partition |
| 8 | Volume Header partition |
| 10 | Whole Disk partition |
The Volume Header partition must start at the first sector on the disk. It contains the disk label in the first sector, and a rudimentary filesystem (readable by the PROM Monitor) in the rest of the partition.
