(And yet another increase on the electricity bill. :\/)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CPU is a Ryzen 9 3950X, and the motherboard is an X570 Aorus Master. Just one problem&#8211; after I built the server, put my Unraid drives in it, and made sure it booted up, I removed the GPU, moved it into the corner, and discovered that it wouldn&#8217;t POST after I moved it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What gives? Well, apparently, these motherboards absolutely insist that they <em>must<\/em> have a working GPU, with a working display, attached before it will proceed with powering on. Which is insane, but, well, there&#8217;s a workaround.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Here&#8217;s what you have to do:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Have a GPU and monitor attached. Enter the BIOS.<\/li>\n\n\n\n<li>Under &#8220;Settings -> IO&#8221;, Set &#8220;Initial Display Output&#8221; to &#8220;PCIe 3 Slot&#8221;<\/li>\n\n\n\n<li>Under &#8220;Settings -> Boot&#8221;, Set:\n<ul class=\"wp-block-list\">\n<li>Fast Boot -> Enabled<\/li>\n\n\n\n<li>VGA Support -> Auto<\/li>\n\n\n\n<li>CSM Support -> Disabled<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Save settings, shut down, and remove the GPU. <strong>For the next boot only<\/strong>, the &#8220;VGA&#8221; light on the motherboard, indicating a problem that blocks boot, will still light up, but boot will proceed as normal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you reboot again, you&#8217;ll have to re-attach a GPU, re-enter the BIOS, shut down again, and re-remove it before it&#8217;ll POST headless. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Why? I have no idea. But this is, frankly, a plus for me, as it further discourages me from touching the device that I need to be reliable, always-on, and <em>not tinkered with<\/em>, or at least tinkered with as little as possible. Such a high barrier to rebooting means that I&#8217;m unlikely to do it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anyway. Hope this helps someone.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sort of, anyhow.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-307","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/nocoffei.com\/index.php?rest_route=\/wp\/v2\/posts\/307","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nocoffei.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nocoffei.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nocoffei.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nocoffei.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=307"}],"version-history":[{"count":0,"href":"https:\/\/nocoffei.com\/index.php?rest_route=\/wp\/v2\/posts\/307\/revisions"}],"wp:attachment":[{"href":"https:\/\/nocoffei.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=307"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nocoffei.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=307"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nocoffei.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=307"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
