mode

Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs. The mode gets its name from the fact that addresses in real mode always correspond to real locations in memory. Real mode is characterized by a 20-bit segmented memory address space (giving 1 MB of addressable memory) and unlimited direct software access to all addressable memory, I/O addresses and peripheral hardware. Real mode provides no support for memory protection, multitasking, or code privilege levels.
Before the introduction of protected mode with the release of the 80286, real mode was the only available mode for x86 CPUs; and for backward compatibility, all x86 CPUs start in real mode when reset, though it is possible to emulate real mode on other systems when starting in other modes.

    Does anyone know why the Cyberster doesn't allow the use of ACC Cruise Control when using the Custom Drive mode? Is this common on all MGs?

    Mode switch not working

    Noticed the last few drives that I can’t select Sport. Am able to select Eco but once in Eco I can’t change back to normal. Is there a way to reset the car or something or should I take it to the dealer to look at? (24 plate 5 SE)

    Aggressive Turtle / Low Power mode after last dealership visit

    Does anyone else have any bother with Turtle / Low Power mode? Since a dealership visit for a service and various updates my MG4 seems to be going into turtle / low power mode earlier than ever before.

    How Driving Mode Affects The mpg.

    Do any of our wise forum members know how the charging system works? Let me explain...most of my driving is around town, does this mean the auxiliary battery gets very little charge? In other words, like the old 12V batteries needed a good run now and then to fully charge, is it the same with...

    Ultra Eco Mode

    Highest mi/kWh achieved so far ?. Amazing what a descent of Sutton Bank rewards you with! For some reason it seems I forgot to record the figures after the ascent ?

    Light or dark screen confusion

    Hi, I just ordered an MG4 Trophy extended. My first ever new car. I'm trying to work out if there is a dark mode for the infotainment system screen. I have asked my dealer (car... nothing else) whether the screen has a dark mode I can activate, as I don't like the light grey theme, and prefer...

    Can't disable tow mode

    I have searched and have not found anybody else mention this. I have a towbar fitted to my MG4 and when I connect my back rack with the 13 pin electrics the car automatically switches to tow mode. That is great, except it disables all drive aids including cruise control, which is madness?? The...

    Car not charging to Health Mode, defaults to 100%

    I set the car (MG4 64kwh) to charge overnight to 80% from the incar settings. I have also checked the app is set to 80%. However the car charges to 100%. This has happened on 4 of the last 5 charges. I have also noticed the app periodically resets itself to 100% and changes to default setting...

    Battery health mode

    I was wondering if this common to all MG4 models, or just my trophy. When I select “battery health mode “ in my vehicle, it always charges to 100% And the option no longer seems available under EV management in the app anymore? I also select 80% in the Octopus energy app and that also get...
