▸ Live DOS Session

Booting X86.WORLD DOS...

Click the screen or the button above to capture keyboard input.  ·  Runs entirely in your browser — nothing is installed on your machine.  ·  Type freely: it's a real DOS shell.

▸ What Just Happened?

You're looking at a real cut-down FreeDOS machine running inside your browser via v86, a full x86 CPU emulator compiled in WebAssembly. The emulated machine has an RTL8029-compatible network card, connected via WebSocket to a relay server on x86.world infrastructure in Seattle, USA.

That relay bridges the emulated Ethernet frames into a real virtual network — complete with DHCP, DNS, and more. The in-browser DOS machine gets a real network IP address and can reach the internet just like any other machine on a LAN. mTCP NetDrive then connects to the x86.world disk archive over UDP and mounts a vintage disk image as a live drive letter.

No plugins. No downloads. No configuration. Just a browser tab, a virtual x86 CPU, and 40 years of computing history right at your fingertips before you even look to try on real vintage hardware.

▸ Things To Try

1
Press a key to connect

After FreeDOS boots you'll see the x86.world welcome screen. Click the emulator to focus it, then press any key to begin connecting to the network.

2
Explore the archive

Once connected you'll land at a DOS prompt on the mounted drive. Type DIR to see what's there. Navigate with CD foldername or load the original menu with PCPLUS.BAT.

3
Run programs

Find an .EXE or .COM and type its name. Programs run directly from the network drive — no local copying needed.

4
Mount a different disk

Disconnect: A:\NETDRIVE DISCONNECT C:
Reconnect to any image from dl.x86.world: NETDRIVE CONNECT 192.168.86.1 image-name.img C:

5
Use classic DOS commands

Everything works: TYPE, COPY, MORE, FIND, EDIT. A complete, real DOS environment.

6
Want the real thing?

This runs at browser speeds. On real hardware — a 486, a Pentium, even an 8088 — NetDrive flies, and programs run at the right speeds. Visit brutman.com/MTCP to set up your own machine.

TIP: Writes work but don't persist — the archive resets on disconnect. Every visitor gets their own private writable copy of the disk. Run programs, create files, do whatever you like. The original is always safe.
