   9           were partitioned under an operating system running on a different
  10           architecture than your Linux system.
  11
  12           Note that the answer to this question won't directly affect the
  13           kernel: saying N will just cause the configurator to skip all
  14           the questions about foreign partitioning schemes.

 128         help
 129           FreeBSD uses its own hard disk partition scheme on your PC. It
 130           requires only one entry in the primary partition table of your disk
 131           and manages it similarly to DOS extended partitions, putting in its
 132           first sector a new partition table in BSD disklabel format. Saying Y
 133           here allows you to read these disklabels and further mount FreeBSD
 134           partitions from within Linux if you have also said Y to "UFS

 149         help
 150           Like most systems, Solaris x86 uses its own hard disk partition
 151           table format, incompatible with all others. Saying Y here allows you
 152           to read these partition tables and further mount Solaris x86

 157         bool "Unixware slices support"
 158         depends on PARTITION_ADVANCED && MSDOS_PARTITION
 159         ---help---
 160           Like some systems, UnixWare uses its own slice table inside a
 161           partition (VTOC - Virtual Table of Contents). Its format is
 162           incompatible with all other OSes. Saying Y here allows you to read
 163           VTOC and further mount UnixWare partitions read-only from within
 164           Linux if you have also said Y to "UFS file system support" or
 165           "System V and Coherent file system support", above.
 166
 167           This is mainly used to carry data from a UnixWare box to your
 168           Linux box via a removable medium like magneto-optical, ZIP or
 169           removable IDE drives. Note, however, that a good portable way to
 170           transport files and directories between unixes (and even other
 171           operating systems) is given by the tar program ("man tar" or
 172           preferably "info tar").
 173
 174           If you don't know what all this is about, say N.

 177         bool "Windows Logical Disk Manager (Dynamic Disk) support"

 179         ---help---
 180           Say Y here if you would like to use hard disks under Linux which
 181           were partitioned using Windows 2000's/XP's or Vista's Logical Disk
 182           Manager.  They are also known as "Dynamic Disks".
 183
 184           Note this driver only supports Dynamic Disks with a protective MBR
 185           label, i.e. DOS partition table.  It does not support GPT labelled
 186           Dynamic Disks yet as can be created with Vista.
 187
 188           Windows 2000 introduced the concept of Dynamic Disks to get around
 189           the limitations of the PC's partitioning scheme.  The Logical Disk
 190           Manager allows the user to repartition a disk and create spanned,
 191           mirrored, striped or RAID volumes, all without the need for
 192           rebooting.
 193
 194           Normal partitions are now called Basic Disks under Windows 2000, XP,
 195           and Vista.

 205           Say Y here if you would like LDM to log verbosely.  This could be
 206           helpful if the driver doesn't work as expected and you'd like to
