What are the major differences between BIOS and DOS routines and what are the situations in which you will prefer BIOS services over DOS?”

the 2 are completely different.
DOS tells a computerwhat to do, where BIOS tells a computer what it is and how to run the hardware connected to it -- DOS simply allows the computer to do things AFTER it knows what it is....
2 things are completely different - Hence the Basic Input/Output....and DOS being an Operating System...

The Bios and Dos are two different things but you have to have both, A binary language that tells the computer who you are to talk to all the computer components in the same language, (English for an example) it operates the CPU the interprets the commands from the key board and sends the information using it's language to the hard drive and other components you have to have both Dos Disk operating system, and bios maching operating system to get a computer to work. the Disk works by turning 0's and 1's on the drive to stored readable information

It's even worse than that. BIOS ("Basic Input/Output System") is the set of instructions that just tells the motherboard how to turn on and how to operate the fundamental devices on the system, like a keyboard. Once the computer's powered up and running, the BIOS is done.
DOS ("Disk Operating System") is used to run everything after the computer's basic functions are powered up. So, unless you're writing motherboard instructions, it's most likely that you would be dealing with DOS services over BIOS services.
