From 4b0536ce7cd55eedc52d13497bea59d91e8924d8 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 2 Mar 2024 23:00:09 +0000 Subject: [PATCH 12/37] 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.
