I'm looking for an example piece of code t3at will put the 386 into
virtual 8086 mode and bring up dos. A book I have seems to have such a program,
but I'm unable to read it cause I'm blind. It's taking me forever to get into
this book and get all the info I need. The direction I'm working in is this.
I'd like to put the 386 in virtual 386 mode and bring up dos but, before I do,
I'd like to program the debug registers to suspend dos and go back into 386 mode
and service some sort of interrupt routine if a given range of memory is
accessed. Can I do this? My plan is to translate direct screen writes into
com-port data.
As always, any help would be greatly appreciated.
