The bios I got on my laptop has effectively 0 keyboard navigability, no shortcut to search, scroll wheel does not work, sensibility is off, somehow only works properly with the touchpad and fails to work with a generic cheap usb mouse that as as far as I can tell is fully complaint to the usb spec as I have had 0 issues with it in any OS without the need for any custom drivers, tab navigation is effectively non functional, arrow key navigation is not there at all, there a “advanced mode” that I discovered with Dell’s custom software that allows changing bios settings from a live OS with the use of custom WMI_ACPI extensions not documented anywhere that I can find from which I can enable a hidden advanced mode that simplies showa more options in the bios but doesnt overhaul the navigation, it shows very advanced options that surely shouldnt just be shown by default such as battery charge limmit, battery start charging threshhold, and many other misceleanous settings that have no reason to be labelled as “advanced”
