From 61041d49b94236400e836b8ea518d3a064b95c4e Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 2 Mar 2024 23:00:09 +0000 Subject: [PATCH 2/2] dell/optiplex_9020: Disable IOMMU by default Needed to make graphics cards work. Turning it on is recommended if only using iGPU, otherwise leave it off by default. The IOMMU is extremely buggy when a graphics card is used. Leaving it off by default will ensure that the default ROM images in Libreboot will work on any setup.
