Try CopperOS

The embedded v86 session loads copperos.iso automatically, so the Copperhead desktop can begin booting as soon as the emulator frame is ready.

Open full emulator Download ISO

Live emulator Loading hosted v86 with copperos.iso.
What loads

CopperOS v1.0 Copperhead boots directly from the ISO.

The frame points at the hosted v86 emulator with the CopperOS ISO already attached as boot media. If a browser or network blocks embedding, the full emulator button opens the same ready-to-boot session in a new tab.

Release profile

Classic startup into a desktop

Copperhead starts with a NASM boot sector, enters a freestanding 32-bit C kernel, draws staged boot screens, and then moves through setup into the desktop.
