# SPDX-License-Identifier: GPL-2.0 # # Partition configuration # 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. config ACORN_PARTITION bool "Acorn partition support" if PARTITION_ADVANCED default y if ARCH_ACORN help Support hard disks partitioned under Acorn operating systems. config ACORN_PARTITION_CUMANA bool "Cumana partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION help Say Y here if you would like to use hard disks under Linux which were partitioned using the Cumana interface on Acorn machines. config ACORN_PARTITION_EESOX bool "EESOX partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION config ACORN_PARTITION_ICS bool "ICS partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION help Say Y here if you would like to use hard disks under Linux which were partitioned using the ICS interface on Acorn machines. config ACORN_PARTITION_ADFS bool "Native filecore partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION help 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 `Y' here, Linux will support disk partitions created under ADFS. config ACORN_PARTITION_POWERTEC bool "PowerTec partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION help Support reading partition tables created on Acorn machines using the PowerTec SCSI drive. config ACORN_PARTITION_RISCIX bool "RISCiX partition support" if PARTITION_ADVANCED default y if ARCH_ACORN depends on ACORN_PARTITION help Once upon a time, there was a native Unix port for the Acorn series of machines called RISCiX. If you say 'Y' here, Linux will be able to read disks partitioned under RISCiX. config AIX_PARTITION bool "AIX basic partition table support" if PARTITION_ADVANCED help 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 OSF_PARTITION bool "Alpha OSF partition support" if PARTITION_ADVANCED default y if ALPHA help Say Y here if you would like to use hard disks under Linux which were partitioned on an Alpha machine. config AMIGA_PARTITION bool "Amiga partition table support" if PARTITION_ADVANCED default y if (AMIGA || AFFS_FS=y) help Say Y here if you would like to use hard disks under Linux which were partitioned under AmigaOS. config ATARI_PARTITION bool "Atari partition table support" if PARTITION_ADVANCED default y if ATARI help Say Y here if you would like to use hard disks under Linux which were partitioned under the Atari OS. config IBM_PARTITION bool "IBM disk label and partition support" depends on PARTITION_ADVANCED && S390 help Say Y here if you would like to be able to read the hard disk partition table format used by IBM DASD disks operating under CMS. Otherwise, say N. config MAC_PARTITION bool "Macintosh partition map support" if PARTITION_ADVANCED default y if (MAC || PPC_PMAC) help Say Y here if you would like to use hard disks under Linux which were partitioned on a Macintosh. config MSDOS_PARTITION bool "PC BIOS (MSDOS partition tables) support" if PARTITION_ADVANCED default y help Say Y here. 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. config MINIX_SUBPARTITION bool "Minix subpartition support" depends on PARTITION_ADVANCED && MSDOS_PARTITION help Minix 2.0.0/2.0.2 subpartition table support for Linux. Say Y here if you want to mount and use Minix 2.0.0/2.0.2 subpartitions. config SOLARIS_X86_PARTITION bool "Solaris (x86) partition table support" depends on PARTITION_ADVANCED && MSDOS_PARTITION help Like most systems, Solaris x86 uses its own hard disk partition table format, incompatible with all others. Saying Y here allows you to read these partition tables and further mount Solaris x86 partitions from within Linux if you have also said Y to "UFS file system support", above. 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. For a fuller description read <file:Documentation/admin-guide/ldm.rst>. If unsure, say N. config LDM_DEBUG bool "Windows LDM extra logging" depends on LDM_PARTITION help Say Y here if you would like LDM to log verbosely. This could be helpful if the driver doesn't work as expected and you'd like to report a bug. If unsure, say N. config SGI_PARTITION bool "SGI partition support" if PARTITION_ADVANCED default y if DEFAULT_SGI_PARTITION help Say Y here if you would like to be able to read the hard disk partition table format used by SGI machines. config ULTRIX_PARTITION bool "Ultrix partition table support" if PARTITION_ADVANCED default y if MACH_DECSTATION help Say Y here if you would like to be able to read the hard disk partition table format used by DEC (now Compaq) Ultrix machines. Otherwise, say N. config SUN_PARTITION bool "Sun partition tables support" if PARTITION_ADVANCED default y if (SPARC || SUN3 || SUN3X) help Like most systems, SunOS uses its own hard disk partition table format, incompatible with all others. Saying Y here allows you to read these partition tables and further mount SunOS partitions from within Linux if you have also said Y to "UFS file system support", above. This is mainly used to carry data from a SPARC under SunOS to your Linux box via a removable medium like magneto-optical or ZIP 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 KARMA_PARTITION bool "Karma Partition support" depends on PARTITION_ADVANCED help Say Y here if you would like to mount the Rio Karma MP3 player, as it uses a proprietary partition table. config EFI_PARTITION bool "EFI GUID Partition support" if PARTITION_ADVANCED default y select CRC32 help Say Y here if you would like to use hard disks under Linux which were partitioned using EFI GPT. config SYSV68_PARTITION bool "SYSV68 partition table support" if PARTITION_ADVANCED default y if VME help Say Y here if you would like to be able to read the hard disk partition table format used by Motorola Delta machines (using sysv68). Otherwise, say N. config CMDLINE_PARTITION bool "Command line partition support" if PARTITION_ADVANCED help Say Y here if you want to read the partition table from bootargs. The format for the command line is just like mtdparts.
