It is monolithic, mostly compile-time configured, and supports only CGA/VGA, keyboard, and PC speaker. A sibling project, GentleOS/32, targets i386 hardware with 4 MB RAM and VGA output. Both projects aim to provide a simple platform for tinkering with retro hardware and running graphical apps on bare metal. ## Full article daily.dev links to this article rather than hosting it.
