For instance, resolution 1024 768 sets the resolution to 1024x768. On UEFI systems, resolution 1 sets video mode 1, the resolution of which varies from system to system. If you set a resolution that doesn't work on a UEFI-based system, rEFInd displays a message along with a list of valid modes. On an system built around EFI 1.x (such as a Mac), setting an incorrect resolution fails silently; you'll get the system's default resolution. You'll also get the system's default resolution if you set both resolution values to 0 or if you pass anything but two numbers.

This may be useful to keep duplicate boot loaders out of the menu (say, if EFI/Boot/bootx64.efi is a duplicate of another boot loader); or to keep drivers or utilities out of the boot menu, if you've stored them in a subdirectory of EFI. This option takes precedence over also_scan_dirs; if a directory appears in both lists, it will not be scanned. + Adds the specified directory or directories to a directory "blacklist"—these directories are not scanned for boot loaders. You may optionally precede a directory path with a volume name and a colon to limit the blacklist to that volume. For instance, EFI/BOOT prevents scanning the EFI/BOOT directory on all volumes, whereas ESP:EFI/BOOT blocks scans of EFI/BOOT on the volume called ESP but not on other volumes. You can use a filesystem number, as in fs0, in place of a volume name. This token may be useful to keep duplicate boot loaders out of the menu (say, if EFI/BOOT/bootx64.efi is a duplicate of another boot loader); or to keep drivers or utilities out of the boot menu, if you've stored them in a subdirectory of EFI. This option takes precedence over also_scan_dirs; if a directory appears in both lists, it will not be scanned. dont_scan_files or don't_scan_files - Filename(s) + filename(s) Adds the specified filename or filenames to a filename "blacklist"—these files are not included as boot loader options even if they're found on the disk. This is useful to exclude support programs (such as shim.efi and MokManager.efi) and drivers from your OS list. The default value is shim.efi, MokManager.efi, TextMode.efi, ebounce.efi, GraphicsConsole.efi. scan_all_linux_kernels - None or 0 + none or 0 When set, causes rEFInd to add Linux kernels (files with names that begin with vmlinuz or bzImage) to the list of EFI boot loaders, even if they lack .efi filename extensions. The hope is that this will simplify use of rEFInd on distributions that provide kernels with EFI stub loader support but that don't give those kernels names that end in .efi. Of course, the kernels must still be stored on a filesystem that rEFInd can read, and in a directory that it scans. (Drivers and the also_scan_dirs options can help with those issues.) Note that this option can cause unwanted files to be improperly detected and given loader tags, such as older kernels without EFI stub loader support. Versions of rEFInd prior to 0.5.0 left this option commented out in the refind.conf-sample file, but as of version 0.5.0, this option is enabled in the default configuration file. The program default remains to not scan for such kernels, though, so you can delete or uncomment this option to keep them from appearing in your boot menu. Passing any option but 0 causes scans for all kernels to occur; passing a 0 causes these kernels to not be scanned. (This could be useful if you want to override a setting of scan_all_linux_kernels in an included secondary configuration file.) default_selection - A substring of a boot loader's title; or a numeric position + a substring of a boot loader's title; or a numeric position Sets the default boot OS based on the loader's title, which appears in the main menu beneath the icons when you select the loader. You can enter any substring of the title as the default_selection, so long as it's two or more characters in length. It's best to use a unique substring, since rEFInd stops searching when it finds the first match. Because rEFInd sorts entries within a directory in descending order by file modification time, if you specify a directory (or volume name, for loaders in a partition's root directory) as the default_selection, the most recent loader in that directory will be the default. One-character entries are matched against the first character of the title, except for digits, which refer to the numeric order of the boot loader entries. @@ -328,7 +328,7 @@ default_selection elilo disabled - None + none Disable an entry.
