It is possible to write code without any OS, put it on hard drive, optical drive or USB drive, at specific address and run it. It's also possible to run such code from the network (network boot option).

Also it is possible to run code like an extension BIOS, well, in fact CPU juts jumps to user code and neither BIOS nor OS works but user code does.

Here are examples of some RussiaRussian security PCI boards, which run its own program before any OS can take a control. The boards, shortly, serve for indentfication and authentication users and run graphical interfaces, can operate with file systems, etc.
