From ca28255db8f18dbcd2db077fb18a6075792ad41c Mon Sep 17 00:00:00 2001 From: Nicholas Chin Date: Sun, 17 Dec 2023 18:02:29 -0700 Subject: README.md: Add instructions for relaxing memory permissions As this utility requires access to /dev/mem, the default protections of Linux and OpenBSD must be relaxed to allow this. Make a note of this in the instructions. --- util/dell-flash-unlock/README.md | 2 ++ 1 file changed, 2 insertions(+) (limited to 'util') diff --git a/util/dell-flash-unlock/README.md b/util/dell-flash-unlock/README.md index 7d9b4b85..fd000efc 100644 --- a/util/dell-flash-unlock/README.md +++ b/util/dell-flash-unlock/README.md @@ -8,6 +8,8 @@ E6400, which mainly seem to be the Latitude and Precision lines starting from around 2008 (E6400 era). ## TL;DR +On Linux, ensure you are booting with the `iomem=relaxed` kernel parameter. +On OpenBSD, ensure you are booting with securelevel set to -1.
