777be the directory containing the initial configuration file.  If no
778configuration file is found, <strong>SYSLINUX</strong> should default to the
779install-time working directory, however this is a known issue with some
780versions including 4.06.</p></div>
781<div class="paragraph"><p>At start, the initial working directory for <strong>PXELINUX</strong> will be the
782parent directory of pxelinux.0 unless overridden with DHCP option 210.
783If no configuration file is found, <strong>PXELINUX</strong> will start a timer to
784reboot the system in an attempt to restart the boot process and resolve
785a possible transient issue.</p></div>

788<h3 id="_alternate_filenames">ALTERNATE FILENAMES</h3>
789<div class="paragraph"><p>For kernel-like file names given on the command line, <strong>Syslinux</strong> will
790attempt to append file name extensions to the specified file name when
791the file is not found in the following order: .0[<strong>PXELINUX</strong> only],
792.bin[<strong>ISOLINUX</strong> only], .bs[<strong>SYSLINUX</strong> only], .bss[<strong>SYSLINUX</strong> only],
793.c32, .cbt[Up to 4.06], .com[Up to 4.06] and .img[<strong>ISOLINUX</strong> 1.65-4.04 only].</p></div>

796<h3 id="_path_rules">PATH RULES</h3>
797<div class="paragraph"><p>The current working directory is <strong>always</strong> searched first, before PATH,
798when attempting to open a filename. The current working directory is
799not affected when specifying a file with an absolute path. For
800example, given the following file system layout,</p></div>

807        /foo/
808                libls.c32</code></pre>
809</div></div>
810<div class="paragraph"><p>assuming that the current working directory is /boot/foo, and assuming
811that libls.c32 is a dependency of ls.c32, executing /boot/bin/ls.c32
812will cause /boot/foo/libls.c32 to be loaded, not /boot/bin/libls.c32,
813even if /boot/bin is specified in the PATH directive of a config file.</p></div>
814<div class="paragraph"><p>The reason that things work this way is that typically a user will
815install all library files in the Syslinux installation directory, as
816specified with the --directory installer option. This method allows
817the user to omit the PATH directive from their config file and still
818have things work correctly.</p></div>
