GentleOS/32

A hobby operating system for vintage 32-bit PCs.

Its goal is to provide a simple platform for tinkering with retro hardware and running graphical interactive apps on bare metal.

At minimum, it only requires an i386 CPU, 4MB of RAM, and a VGA display capable of 640x480x16 mode.

By design it’s entirely monolithic, mostly configured at compile time, and only supports standard PC devices: VGA/SVGA, keyboard, PS/2 mouse, serial mouse, PC speaker. The only future plans are bugfixes, optimizations, and adding more apps.

GentleOS/32 has a pure 16-bit spin-off called GentleOS/16, which targets devices as old as 80186.

For details on building and running, see USAGE.md.
