SYS Files

[alan b]

There are many .sys files like keyboard.sys
and diskio.sys and so on in the Windows Directory. I understand that these
sys files are tied to operating system already compiled at Microsoft before
shipping.
But I would like to see how it is created in a simple c program. Is it
possible to write in C and rename it to .sys extension from .c? are there
links to these code samples?

..SYS files (drivers) are, most nearly, DLLs. typically, they're written in
C (but some are written in C++). To develop a driver, you need to use the
DDK - Driver Developer's Kit, which is available from Microsoft for a
nominal charge.

Developing drivers for Windows is complex and subtle - there's almost no
such thing as a simple driver.
