- No. You misunderstand me. What I am saying is that the BIOS is just as
- much a part of DOS (in the abstraction called an "Operating System") just
- as much as the Network Layer is part of the Transport Layer (in the OSI
- model of a networking environment) because the Transport Layer can't
- *exist* without the Network Layer (at least and be runnable).
-
- Sure the actual underlying implementation is different (e.g., the particaulr
- hardware doesn't have a PC BIOS... but the ABSTRACTION is still there).
