## Accessibility

The BIOS is not text-only: there is some menu composed of a list of blocks like in a graphical interface. Some parts are playing with mixes of white/blue color, but main parts are black-on-white and interface is mainly clean, so it might work well with OCR software. It does provide mouse support.

Note: Blind users should request the help of a sighted person to change BIOS settings.

Selecting the boot medium and changing settings may be accessed by pressing `F9` during POST.
