760<div class="paragraph"><p>Install <strong>SYSLINUX</strong> to the <em>DEVICE</em>/<em>PATH</em>, altering the boot sector and
761installing the <em>ldlinux.sys</em> boot loader file.  For the Linux installer
762extlinux, <em>PATH</em> is the desired path for the control files on a mounted,
763supported file system and sets the install-time working directory.  For
764all others, <em>DEVICE</em> must specify a FAT12/FAT16/FAT32 file system.  For
765the Linux installers syslinux and syslinux-mtools, <em>DEVICE</em> should be an
766unmounted file system.  For the DOS/Win32/Win64 installers, <em>DEVICE</em>
767should be a drive like <em>a:</em> (case insensitive).</p></div>
768<div class="paragraph"><p>For versions ~4.00 and later, either -i/--install or -U/--update must be
769specified unless modifying the ADV of an existing install (options
770tagged with <em>ADV</em>) or requesting the help/usage or version info, .</p></div>
771<div class="paragraph"><p>If, during boot, the Shift or Alt keys are held down, or the Caps or
772Scroll locks are set, <strong>Syslinux</strong> will display a <strong>lilo</strong>(8) -style "boot:"
773prompt. The user can then type a kernel file name followed by any kernel
774parameters. The <strong>Syslinux</strong> bootloader does not need to know about the
775kernel or config files in advance.</p></div>
776<div class="paragraph"><p><strong>Syslinux</strong> supports the loading of initial ramdisks (initrd) and the
777bzImage kernel format.</p></div>
778<div class="paragraph"><p>Please note, the ldlinux.sys boot loader file is flagged as immutable
779(where applicable) and is modified after copying in to help ensure
780boot-time integrity.  File systems with a sufficiently large boot loader
781reserved area, like btrfs, will have ldlinux.sys installed there rather
782than as a normal file.  Prior to version 4.00, extlinux would install a
783file extlinux.sys which versions 4.00 and later installers will replace with ldlinux.sys.</p></div>
