PC system | questions

1) What are the specific limitation of a computer system that provides no operation system ? what must be done to load and execute programs?

2) What are the limitations of providing a BIOS in ROM ?

3) A new idea in operating system is to provide as small a kernel as possible and to make all other modules optional. What are the minimum services that must be provided in such a miniature kernel ?

4) Illustrate, step by step, the way in which a circular register buffer works by showing its operation for a simple program that you invent that is made up of subroutines and functions with local variables and passed arguments. Place your arguments and variables into the illustrations to clarify your discussion

help ... ani ideas ?

1. You can't do diddly, aside from configure the BIOS.
2. Can't upgrade the BIOS to fix bugs or stuff. (Settings however I believe are stored in CMOS memory?? :confused: )
3. FS access, probably some standard mathematical logic, support for executing files (I'm really, really guessing here)., support for installing the modules.
4. What?

How is the idea of a small kernel with loadable modules in any way new? Linux has been doing it for years.

As is the HURD design, in places.

Also, Windows has a similar design in its kernel (small base, load extra drivers as .sys, .vxd, .dll, etc.).

Hardly a new idea.
