<td>Tells rEFInd what methods to use to locate boot loaders. The <tt>internal</tt>, <tt>external</tt>, and <tt>optical</tt> parameters tell rEFInd to scan for EFI boot loaders on internal, external, and optical (CD, DVD, and Blu-ray) devices, respectively. The <tt>hdbios</tt>, <tt>biosexternal</tt>, and <tt>cd</tt> parameters are similar, but scan for BIOS boot loaders. (Note that the BIOS options are likely to be useless on UEFI PCs.) The <tt>manual</tt> parameter tells rEFInd to scan the configuration file for manual settings. You can specify multiple parameters to have the program scan for multiple boot loader types. When you do so, the order determines the order in which the boot loaders appear in the menu. The default is <tt>internal, external, optical</tt>.</td>
