config PARTITION_ADVANCED

bool "Advanced partition selection"

help
|
Say Y here if you would like to use hard disks under Linux which
|
were partitioned under an operating system running on a different
|
architecture than your Linux system.
|
|
Note that the answer to this question won't directly affect the
|
kernel: saying N will just cause the configurator to skip all
|
the questions about foreign partitioning schemes.
|
|
If unsure, say N.

The Acorn Disc Filing System is the standard file system of the

RiscOS operating system which runs on Acorn's ARM-based Risc PC

systems and the Acorn Archimedes range of machines. If you say

Say Y here if you would like to be able to read the hard disk

partition table format used by IBM or Motorola PowerPC machines

running AIX. AIX actually uses a Logical Volume Manager, where
|
"logical volumes" can be spread across one or multiple disks,

but this driver works only for the simple case of partitions which

are contiguous.

Otherwise, say N.

config BSD_DISKLABEL

bool "BSD disklabel (FreeBSD partition tables) support"

depends on PARTITION_ADVANCED && MSDOS_PARTITION
|
help
|
FreeBSD uses its own hard disk partition scheme on your PC. It
|
requires only one entry in the primary partition table of your disk
|
and manages it similarly to DOS extended partitions, putting in its
|
first sector a new partition table in BSD disklabel format. Saying Y
|
here allows you to read these disklabels and further mount FreeBSD
|
partitions from within Linux if you have also said Y to "UFS
|
file system support", above. If you don't know what all this is
|
about, say N.

Like most systems, Solaris x86 uses its own hard disk partition

table format, incompatible with all others. Saying Y here allows you

partitions from within Linux if you have also said Y to "UFS

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

config LDM_PARTITION
|
bool "Windows Logical Disk Manager (Dynamic Disk) support"
|
depends on PARTITION_ADVANCED
|
---help---
|
Say Y here if you would like to use hard disks under Linux which
|
were partitioned using Windows 2000's/XP's or Vista's Logical Disk
|
Manager. They are also known as "Dynamic Disks".
|
|
Note this driver only supports Dynamic Disks with a protective MBR
|
label, i.e. DOS partition table. It does not support GPT labelled
|
Dynamic Disks yet as can be created with Vista.
|
|
Windows 2000 introduced the concept of Dynamic Disks to get around
|
the limitations of the PC's partitioning scheme. The Logical Disk
|
Manager allows the user to repartition a disk and create spanned,
|
mirrored, striped or RAID volumes, all without the need for
|
rebooting.
|
|
Normal partitions are now called Basic Disks under Windows 2000, XP,
|
and Vista.
