The /usr/mdec/sgivol program prepares an SGI Volume Header to be used to boot NetBSD. The SGI PROM is able to load executables within the header, which in turn are used to load the kernel from another file system.
The following options are available: -f Force the operation. Do not ask the user before proceeding. -h Set the size of the newly initialized volume header in blocks. One block is 512 bytes. The default volume header size is 3135 blocks (1.53MB). -q Suppress output.
The numerical partition types for the volume header include: 0: Volume Header 1: Replicated Tracks 2: Replicated Sectors 3: Raw 4: BSD4.2 file system 5: SysV file system 6: Entire Volume (all disk blocks) 7: EFS 8: Logical Volume 9: Raw Logical Volume 10: XFS 11: XFS Log 12: XLV Volume 13: XVM Volume
