Using C the entire way?

Post by Gros »

Is it possible to create an OS only using C? (and inline assembler of course). For instance, the bootloader. It?s hard to find a C compiler that generates 16-bits code(that?s needed in the loader), but if I find one, would it(technically) be possible to write a boot loader in C?

Yes. Relatively large numbers of OS's are written in C (with inline assembler). For the boot loader, there are C compilers capable of generating 16 bit real mode code (some are free/GPL). For example:
