@socketpair I'd suggest to clone the repository and try running it yourself. Currently there's some missing code [here](https://github.com/copy/v86/blob/master/src/cpu.js#L3456). After that it tries to use the APIC and fails. You can...

Status update: I've implemented all APIC features that are required by Windows XP and fixed a few small bugs. It's more-or-less usable now. I'll need to do some more testing...

I have now pushed the remaining pieces to run Windows XP in v86. You can clone the repository, set `ENABLE_ACPI = true` [here](https://github.com/copy/v86/blob/master/src/config.js#L30) and try it out locally. I recommend...
