<p>El cargador de arranque de Haiku puede ayudarle cuando experimente problemas de hardware o quiera elegir qué instalación de Haiku quiere iniciar, si dispone de más de una (seguramente en un CD de instalación o unidad USB).<br/>
También viene muy bien para cuando ha instalado algún componente de software que actúa previniendo el arranque del sistema. para desinstalarlo. La opción <i>Disable user add-ons</i> (Deshabilitar los add-ons de usuario) que se menciona mas abajo, iniciará Haiku sin cargar nunguno de los componentes instalados por el usuario, por ejemplo, un controlador.</p>
<p>Para visualizar las opciones del cargador de arranque, hay que mantener presionada la techa <spanclass="key">SHIFT</span> (de mayúsculas) antes del comienzo del proceso de arranque de Haiku. En de haber un administrador de arranque instalado, empiece a presionar la tecla antes de seleccionar Haiku desde el mismo. Si Haiku es el único sistema operativo instalado, empiece a presionar la tecla mientras se viualizan los mensajes de arranque del BIOS.</p>

<tr><td><b>Select safe mode options</b></td><td></td><td>There are several options to try in case of hardware related trouble or if the system becomes unstable or unbootable because of a misbehaving add-on. When moving the selection bar to an option, a short explanation appears at the bottom of the screen.</td></tr>
Puts the system into safe mode. This can be enabled independently from the other options.</p>
<p><spanclass="menu">Disable user add-ons</span><br/>
Prevents all user installed add-ons from being loaded. Only the add-ons in the system directory will be used. See <ahref="#troubleshooting">Troubleshooting</a> below.</p>
<p><spanclass="menu">Disable IDE DMA</span><br/>
Disables IDE DMA, increasing IDE compatibility at the expense of performance.</p>
Allows to select system files that shall be ignored. Useful e.g. to disable drivers temporarily. See <ahref="#troubleshooting">Troubleshooting</a> below.</p></td></tr>
<tr><td><b>Select debug options</b></td><td></td><td>Here you'll find several options that help with debugging or getting details for a <ahref="../welcome/en/bugreports.html">bug report</a>. Again, a short explanation for each option is displayed at the bottom.</td></tr>
<tr><tdclass="onelinetop"><b>Seleccionar modo de vídeo a prueba de fallos</b></td><td></td><td>Si activó la opción <i>Utilizar modo de vídeo a prueba de fallos</i>, puede configurarse la resolución y la profundidad de color.</td></tr>
<p>If Haiku refuses to boot on your hardware from the get-go, try out setting different options under <spanclass="menu">Select safe mode options</span>. Consider filing a <ahref="../welcome/en/bugreports.html">bug report</a> in any case.</p>
<p>On the other hand, if Haiku only suddenly acts up after you have installed some software, especially hardware drivers, you have several options to get Haiku bootable again to make things right by uninstalling the offending package again:</p>
<ul>
<li><p>Activating <spanclass="menu">Safe mode</span> will prevent most servers, daemons and the UserBootScript from being started.</p></li>
<li><p>Activating <spanclass="menu">Disable user add-ons</span> will prevent using any add-ons (drivers, translators, etc.) you have installed in the user hierarchy under your Home folder.</p></li>
<li><p>If the offending driver, add-on etc. is installed in the system hierarchy, things get a bit more complicated, because that area is read-only. Here, the <spanclass="menu">Blacklist entries</span> comes into play. With it, you can navigate through the whole system hierarchy and disable the component that's messing things up for you by checking an entry with the <spanclass="key">SPACE</span> or <spanclass="key">RETURN</span> key. <spanclass="key">ESC</span> returns you up one level to the parent directory.</p>
<p>Online, there's the article <ahref="http://www.haiku-os.org/blog/barrett/2013-12-15_how_permanently_blacklist_package_file">How to Permanently Blacklist a Package File</a> showing how to make that setting stick.</p></li>
<p>Tras activar una o más opciones, puede regresar de nuevo al menú principal y continuará iniciando, lo cual se presentará con esta pantalla de arranque:</p>
