 ## 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.
 Run `make` to compile the utility, and then run `sudo ./dell_flash_unlock` and
 follow the directions it outputs.

 It is likely that any other Latitude/Precision laptops from the same era as
 devices specifically mentioned in the above list will work as Dell seems to use
 the same ECs in one generation.
 
+## Tested
+These systems have been tested, but were reported as not working with
+dell-flash-unlock. This could be due to user error, a bug in this utility, or
+the feature not being implemented in Dell's firmware. If you have such a system,
