Here I would agree 100%. I used LSI BIOS "GUI" interface and didn't like
it at all. It is more like "norton commander" or "midnight commander" if
anybody still remembers those DOS tools. Anyway, in that LSI BIOS "GUI" I
ended up disregarding mouse, and navigating and choosing actions just by
keyboard ("tab" and "enter" keys, sometimes "esc" key IIRC). I kind of
even didn't think that one could consider that GUI...
