You will want to distinguish between using real and protected mode 
interrupt handlers (a deep subject, one I will not pretend to be 
knowledgeable at until I write my own handler that runs under djgpp). 
Look at the descriptions for the library functions 
_dpmi_get/set_real/protected_mode_vectors().  I think it is a good 
idea as well that you read the DPMI specification (0.9/1.0) and learn 
that well...perhaps like the back of your hand; find it at 
www.delorie.com.  You know that life is tough for those who make the 
decision to write their own interrupt handlers.

> 2)    How to I make my own library (.a file) from scratch?..

If using RHide, just name the target with an 'a.' extension.  If 
using make, there is a standard way of specifying the use of the 'ar' 
command, which is what makes a library out of your objects.  Read the 
documentation on the use of the 'ar' utility.
