Booting an arbitrary partition

Booting an arbitrary partition

You can boot different operating systems or partitions using the bootos(HW) command. You can either specify a partition by number (obtained by entering bootos ?) or by type:

ccpm
concurrent CP/M filesystem

dos
matches any DOS filesystem 

dos_12
DOS 12-bit FAT (file access table)

dos_16
DOS 16-bit FAT

dos_32
DOS 32-bit FAT

dos_ext
DOS extended partition

nt, os2, os2_hpfs
Windows NT, OS/2, or OS/2 HPFS filesystem; bootos cannot distinguish between these

unix
UNIX system filesystem

xenix
XENIX filesystem

For example, the following command loads an OS/2 partition:

   Boot
   : bootos os2
See bootos(HW) for more information.
