Once you boot from your chosen media, you should see something like this:
> OpenBSD/amd64 BOOT 3.18 boot>
If you need to interrupt the boot process for any reason, you can do so at this point. We’ll discuss how to interrupt the boot process in Chapter 5, and reasons for doing so throughout the book.
If you wait five seconds, OpenBSD should boot. The kernel will then introduce itself and begin identifying your hardware.
