<h1>Starthanteraren</h1>
|
|
|
|
<p>Haiku's Boot Loader Options can help when you experience hardware related problems or want to choose which Haiku installation to start, if you have more than one (maybe on an installation CD or USB stick). It's also handy if you have installed a software component that acts up and prevents you from booting Haiku, see <a href="#troubleshooting">Troubleshooting</a> below.</p>
|
|
<p>För att få fram valen i Boot Loader måste du tycka på, och fortsätta hålla ner tangenten <span class="key">SKIFT</span> innan Haikus startprocess. Om du har en boot manager installerad kan du börja hålla ner <span class="key">SKIFT</span> innan du väljer att starta Haiku. Om Haiku är det enda installerade operativsystemet på datorn kan du börja hålla ner tangenten när du fortfarande ser startmeddelanden från BIOS. </p>
|
|
<div class="box-info">On computers that use UEFI for booting instead of the classic BIOS, you need to use the <span class="key">SPACEBAR</span> instead.</div>

<a id="troubleshooting" name="troubleshooting">Troubleshooting</a></h2>
|
|
<p>If Haiku refuses to boot on your hardware from the get-go, try out setting different options under <span class="menu">Select safe mode options</span>. Consider filing a <a href="../../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 so you can uninstall the offending package:</p>
|
|
<ul>
|
|
<li><p>Activating <span class="menu">Safe mode</span> will prevent most servers, daemons and the UserBootscript from being started.</p></li>
|
|
<li><p>Activating <span class="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 activating <span class="menu">Use fail-safe graphics driver</span> solves your troubles by falling back to VESA graphics, you can make the setting permanent by removing the <tt>#</tt> of the line <i>#fail_safe_video_mode true</i> in the text file <span class="path">/boot/home/config/settings/kernel/drivers/kernel</span>.</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 <span class="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 <span class="key">SPACE</span> or <span class="key">RETURN</span> key. <span class="key">ESC</span> returns you up one level to the parent directory.</p>
|
|
<p>Online, there's the article <a href="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>
|
|
<li><p>Under <span class="menu">Select boot volume</span> you can specify what former "version" of Haiku to boot. Every time you un/install a package, the old state is saved and you can boot into it by choosing it from the list presented in the boot loader options.<br />
|
|
So, if you encounter boot problems after installing some package, boot a Haiku state from before that time and uninstall the offending package.</p></li>
