Hello,

Ok, I'm in the process of upgrading to Current as I speak, and after
I get this system running again, I will bring my changes into
current here and Post the diffs for testing.

Status:
kernel mod to put system into VM86 mode
syscall to do this
problems allocing mem to make this useful
looking at Mach DOS,Linux and NetBSD for useful information or creative hacks
allows either 0 or 3 level (at this point only 0 works at all(no iomap))
thinking about a syscall for doing BIOS calls only with a general one later

email me for more details or if you want to help:)

Gary
