hi,

I've been writing a application which uses a packet driver to talk to the
network card, ive been able to pass instructions to the packet driver
through the registers using int86x command but the problem starts when i
send the packet driver a pointer (es:di / code segment:offset) to one of my
programmes functions, when it calls it back teh whole thing just crashes,
without error message. Is this because it is a real mode service trying to
call my protected programme? Is there anyway to call the interrupt and pass
the pointer from my programme so it does not do this?

Thanks,
andy.
