E2B will first display a text-mode screen and show a blue startup banner for 5 seconds when you legacy-boot (not UEFI-boot).
After that it will process the settings in the \_ISO\MyE2B.cfg file and set the required video mode.
If the user has not specified a different graphics mode using the GMODE parameter in the \_ISO\MyE2B.cfg file, then E2B will use 800×600 24/32-bit colour mode by default.
Some graphics adaptors or monitors may have difficulties displaying this mode (perhaps via HDMI or DisplayPort or VGA) and so you may see a garbled or blank screen instead of the 800×600 E2B Main Menu. You can try using the default E2B menu hotkeys below:
- CTRL+F7 – switch to text mode (graphics mode 3) – E2B v2.16+ required
- ALT+F7 – switch to 1024×768 graphics mode (grey background) – E2B v2.16+ required
- CTRL+F8 – restart grub4dos and reload E2B (similar to rebooting but faster)
Note that with some notebooks, you may also have to hold down the Fn key at the same time. There is usually a BIOS configuration option to disable this ‘feature’.
You can configure the MyE2B.cfg configuration file to always load in text mode or 1024×768 mode – see here for more details of ‘themes’.
