Re: [rtl] HARD real-time DOS/Win98

Pardon my asking this (it's slightly offtopic): But what exactly is
Win4Lin?  Is it a commercial Wine-like emulation program?  Or is it more
akin to vmware?  How does it compare to both wine (which does API/Binary
emulation) and vmware (which is expensive but nearly perfectly creates a
virtual intel box under linux).  I am intrigued by your experience with
win4lin and rtlinux, that's why I ask.  (So this inquiry is still
semi-on-topic).
