I would like to write a TSR to provide information on the pentium timer
counter to 16 bit programs.  There is a lot of history here, but basically,
I am using a packet driver to send packets out on an ethernet to measure
network performance.  I don't want to change too much.

So I think I need a 32bit, i.e. protected mode TSR to get the Pentium Timer
value.  I would also like there to be a 16bit, i.e. real mode mechanism to
call the 32bit TSR routines.

Am I right? I know there is more difference between protected and real mode
than simply 16 vs 32 bits but I think this is the important bit for me.

Are there any skeleton codes for what I want to do?

Alternatively, has anyone got the bare bones of interfacing to a real mode
packet driver?

Thanks.
