# Hide user interface elements for personal preference or to increase
# security:
#  banner      - the rEFInd title banner
#  label       - text label in the menu
#  singleuser  - remove the submenu options to boot Mac OS X in single-user
#                or verbose modes; affects ONLY MacOS X
#  hwtest      - the submenu option to run Apple's hardware test
#  arrows      - scroll arrows on the OS selection tag line
#  all         - all of the above
#
#hideui singleuser

# Set the name of a subdirectory in which icons are stored. Icons must
# have the same names they have in the standard directory. The directory
# name is specified relative to the main rEFInd binary's directory. If
# an icon can't be found in the specified directory, an attempt is made
# to load it from the default directory; thus, you can replace just some
# icons in your own directory and rely on the default for others.
# Default is "icons".
#
#icons_dir myicons

# Use a custom title banner instead of the rEFInd icon and name. The file
# path is relative to the directory where refind.efi is located. The color
# in the top left corner of the image is used as the background color
# for the menu screens. Currently uncompressed BMP images with color
# depths of 24, 8, 4 or 1 bits are supported.
#
#banner hostname.bmp

# Custom images for the selection background. There is a big one (144 x 144)
# for the OS icons, and a small one (64 x 64) for the function icons in the
# second row. If only a small image is given, that one is also used for
# the big icons by stretching it in the middle. If only a big one is given,
# the built-in default will be used for the small icons.
#
# Like the banner option above, these options take a filename of an
# uncompressed BMP image file with a color depth of 24, 8, 4, or 1 bits.
#
#selection_big   selection-big.bmp
#selection_small selection-small.bmp

# Use text mode only. When enabled, this option forces rEFInd into text mode.
#
#textonly

# Set the screen's video resolution. Pass this option two values,
# corresponding to the X and Y resolutions. Note that not all resolutions
# are supported. On UEFI systems, passing an incorrect value results in a
# message being shown on the screen to that effect, along with a list of
# supported modes. On EFI 1.x systems (e.g., Macintoshes), setting an
# incorrect mode silently fails. On both types of systems, setting an
# incorrect resolution results in the default resolution being used.
# A resolution of 1024x768 usually works, but higher values often don't.
# Default is "0 0" (use the system default resolution, usually 800x600).
#
#resolution 1024 768

# Launch specified OSes in graphics mode. By default, rEFInd switches
# to text mode and displays basic pre-launch information when launching
# all OSes except OS X. Using graphics mode can produce a more seamless
# transition, but displays no information, which can make matters
# difficult if you must debug a problem. Also, on at least one known
# computer, using graphics mode prevents a crash when using the Linux
# kernel's EFI stub loader. You can specify an empty list to boot all
# OSes in text mode.
# Valid options:
#   osx     - Mac OS X
#   linux   - A Linux kernel with EFI stub loader
#   elilo   - The ELILO boot loader
#   grub    - The GRUB (Legacy or 2) boot loader
#   windows - Microsoft Windows
# Default value: osx
#
#use_graphics_for osx,linux

# Which non-bootloader tools to show on the tools line, and in what
# order to display them:
#  shell           - the EFI shell (requires external program; see rEFInd
#                    documentation for details)
#  gptsync         - the (dangerous) gptsync.efi utility (requires external
#                    program; see rEFInd documentation for details)
#  apple_recovery  - boots the Apple Recovery HD partition, if present
#  mok_tool        - makes available the Machine Owner Key (MOK) maintenance
#                    tool, MokManager.efi, used on Secure Boot systems
#  about           - an "about this program" option
#  exit            - a tag to exit from rEFInd
#  shutdown        - shuts down the computer (a bug causes this to reboot
#                    EFI systems)
#  reboot          - a tag to reboot the computer
# Default is shell,apple_recovery,mok_tool,about,shutdown,reboot
#
#showtools shell, about, reboot

# Directories in which to search for EFI drivers. These drivers can
# provide filesystem support, give access to hard disks on plug-in
# controllers, etc. In most cases none are needed, but if you add
# EFI drivers and you want rEFInd to automatically load them, you
# should specify one or more paths here. rEFInd always scans the
# "drivers" and "drivers_{arch}" subdirectories of its own installation
# directory (where "{arch}" is your architecture code); this option
# specifies ADDITIONAL directories to scan.
# Default is to scan no additional directories for EFI drivers
#
#scan_driver_dirs EFI/tools/drivers,drivers

# Which types of boot loaders to search, and in what order to display them:
#  internal      - internal EFI disk-based boot loaders
#  external      - external EFI disk-based boot loaders
#  optical       - EFI optical discs (CD, DVD, etc.)
#  hdbios        - BIOS disk-based boot loaders
#  biosexternal  - BIOS external boot loaders (USB, eSATA, etc.)
#  cd            - BIOS optical-disc boot loaders
#  manual        - use stanzas later in this configuration file
# Note that the legacy BIOS options require firmware support, which is
# not present on all computers.
# On UEFI PCs, default is internal,external,optical,manual
# On Macs, default is internal,hdbios,external,biosexternal,optical,cd,manual
#
#scanfor internal,external,optical,manual

# Delay for the specified number of seconds before scanning disks.
# This can help some users who find that some of their disks
# (usually external or optical discs) aren't detected initially,
# but are detected after pressing Esc.
# The default is 0.
#
#scan_delay 5

# When scanning volumes for EFI boot loaders, rEFInd always looks for
# Mac OS X's and Microsoft Windows' boot loaders in their normal locations,
# and scans the root directory and every subdirectory of the /EFI directory
# for additional boot loaders, but it doesn't recurse into these directories.
# The also_scan_dirs token adds more directories to the scan list.
# Directories are specified relative to the volume's root directory. This
# option applies to ALL the volumes that rEFInd scans. If a specified
# directory doesn't exist, it's ignored (no error condition results).
# The default is to scan no additional directories.
#
#also_scan_dirs boot,EFI/linux/kernels

# Directories that should NOT be scanned for boot loaders. By default,
# rEFInd doesn't scan its own directory or the EFI/tools directory.
# You can "blacklist" additional directories with this option, which
# takes a list of directory names as options. You might do this to
# keep EFI/boot/bootx64.efi out of the menu if that's a duplicate of
# another boot loader or to exclude a directory that holds drivers
# or non-bootloader utilities provided by a hardware manufacturer. If
# a directory is listed both here and in also_scan_dirs, dont_scan_dirs
# takes precedence. Note that this blacklist applies to ALL the
# filesystems that rEFInd scans, not just the ESP.
#
#dont_scan_dirs EFI/boot,EFI/Dell

# Files that should NOT be included as EFI boot loaders (on the
# first line of the display). If you're using a boot loader that
# relies on support programs or drivers that are installed alongside
# the main binary or if you want to "blacklist" certain loaders by
# name rather than location, use this option. Note that this will
# NOT prevent certain binaries from showing up in the second-row
# set of tools. Most notably, MokManager.efi is in this blacklist,
# but will show up as a tool if present in certain directories. You
# can control the tools row with the showtools token.
# The default is shim.efi,MokManager.efi,TextMode.efi,ebounce.efi,GraphicsConsole.efi
#
#dont_scan_files shim.efi,MokManager.efi

# Scan for Linux kernels that lack a ".efi" filename extension. This is
# useful for better integration with Linux distributions that provide
# kernels with EFI stub loaders but that don't give those kernels filenames
# that end in ".efi", particularly if the kernels are stored on a
# filesystem that the EFI can read. When uncommented, this option causes
# all files in scanned directories with names that begin with "vmlinuz"
# or "bzImage" to be included as loaders, even if they lack ".efi"
# extensions. The drawback to this option is that it can pick up kernels
# that lack EFI stub loader support and other files. Most notably, if you
# want to give a kernel a custom icon by placing an icon with the kernel's
# filename but a ".icns" extension in the same directory as the kernel, this
# option will cause the icon file to show up as a non-functional loader tag.
# Default is to NOT scan for kernels without ".efi" extensions.
#
#scan_all_linux_kernels

# Set the maximum number of tags that can be displayed on the screen at
# any time. If more loaders are discovered than this value, rEFInd shows
# a subset in a scrolling list. If this value is set too high for the
# screen to handle, it's reduced to the value that the screen can manage.
# If this value is set to 0 (the default), it's adjusted to the number
# that the screen can handle.
#
#max_tags 0

# Set the default menu selection.  The available arguments match the
# keyboard accelerators available within rEFInd.  You may select the
# default loader using:
#  - A digit between 1 and 9, in which case the Nth loader in the menu
#    will be the default. 
#  - Any substring that corresponds to a portion of the loader's title
#    (usually the OS's name or boot loader's path).
#
#default_selection 1

# Sample manual configuration stanzas. Each begins with the "menuentry"
# keyword followed by a name that's to appear in the menu (use quotes
# if you want the name to contain a space) and an open curly brace
# ("{"). Each entry ends with a close curly brace ("}"). Common
# keywords within each stanza include:
#
#  volume    - identifies the filesystem from which subsequent files
#              are loaded. You can specify the volume by label or by
#              a number followed by a colon (as in "0:" for the first
#              filesystem or "1:" for the second).
#  loader    - identifies the boot loader file
#  initrd    - Specifies an initial RAM disk file
#  icon      - specifies a custom boot loader icon
#  ostype    - OS type code to determine boot options available by
#              pressing Insert. Valid values are "MacOS", "Linux",
#              "Windows", and "XOM". Case-sensitive.
#  graphics  - set to "on" to enable graphics-mode boot (useful
#              mainly for MacOS) or "off" for text-mode boot.
#              Default is auto-detected from loader filename.
#  options   - sets options to be passed to the boot loader; use
#              quotes if more than one option should be passed or
#              if any options use characters that might be changed
#              by rEFInd parsing procedures (=, /, #, or tab).
#  disabled  - use alone or set to "yes" to disable this entry.
#
# Note that you can use either DOS/Windows/EFI-style backslashes (\)
# or Unix-style forward slashes (/) as directory separators. Either
# way, all file references are on the ESP from which rEFInd was
# launched.
# Use of quotes around parameters causes them to be interpreted as
# one keyword, and for parsing of special characters (spaces, =, /,
# and #) to be disabled. This is useful mainly with the "options"
# keyword. Use of quotes around parameters that specify filenames is
# permissible, but you must then use backslashes instead of slashes,
# except when you must pass a forward slash to the loader, as when
# passing a root= option to a Linux kernel.

# Below are several sample boot stanzas. All are disabled by default.
# Find one similar to what you need, copy it, remove the "disabled" line,
# and adjust the entries to suit your needs.

# A sample entry for a Linux 3.3 kernel with its new EFI boot stub
# support on a filesystem called "KERNELS". This entry includes
# Linux-specific boot options and specification of an initial RAM disk.
# Note uses of Linux-style forward slashes, even in the initrd
# specification. Also note that a leading slash is optional in file
# specifications.

# EFI shells are programs just like boot loaders, and can be
