I'm merging the vm86 stuff with -current. I have the code integrated with the new upages layout in -current, as well as permitting controlled access to the full range of the I/O port space. I also have the VME (Virtual Mode Extensions) working, for the most part, as well as a few other changes. The downside is, it doesn't work perfectly. Executing some DOS programs will wedge the machine, requiring a break into DDB and some mucking around to recover the machine. Unfortunately, I don't forsee having any real free time to work on this for another 2-3 weeks. -- Jonathan
