NOTE: I've read all the FAQ on DPMI (lock,unlock linear region), I know
how to program under DPMI and fool around with interrupts etc.

I've got a sophisticated 'real-time' program (with lots of ISR hooking
etc) and I'd like to lock the ENTIRE program (code,data - everthing) out
of virtual memory disk swaps.  How can I perform this?  Currently I only
lock out the code/data that is critical - but I can't lock out the other
libraries like standard I/O.

I know the programs memory requirements are well under the amount of
available physical memory.

BTW, I'm not keen on modifiy the DJGPP source etc to do this.

Help greatly appreciated,

Matt
