Currently, we only provide BIOS support, but support for UEFI is planned, too. If you'd like to help us with this, check out the [Github issue](https://github.com/phil-opp/blog_os/issues/349).
### BIOS Boot
Almost all x86 systems have support for BIOS booting, even newer UEFI-based machines (they include an emulated BIOS). This is great, because you can use the same boot logic across all machines from the last centuries.
