- Integrate Bochs/QEMU VBE physical LFB mapping directly to hardware video memory (0xFD000000) - Update kernel boot sequence to directly boot into GUI Desktop by default - Fall back to Emergency Kernel TTY Mode upon GUI exit (Esc key / Exit menu item) - Support 'nogui', 'text', 'emergency', and 'single' boot arguments to boot directly into text mode - Remove frame limits so GUI runs persistently
