  I had read a post, a reply to someone asking about trapping I/O port accesses
under 386 p.mode, and the reply said that it could be done using a virtual
device driver.....  

  My question, then, is this:  how does one write a virtual device driver?  how
is it different from a 'regular' device driver?  and, can it be done with Turbo
Assembler?  

  also, I'd like to know how to switch into protected mode (i.e. an interrupt
call, changing the value of a "special" cpu register, etc.).....  386 protected
mode, not 286.....  all the different ways, if at all possible.....  


  please email me.....  I know it's supposedly bad etiquette, but I have a lot
of homework, which precludes me from checking this newsgroup frequently..... :)
