I don't have the time to do it, but maybe someone else does. Although hard disks are getting cheap, so is memory. I think a better improvement would be to allow MINIX to use memory above 640K. On a system with lots of memory and fairly small programs, swapping isn't so important. Andy Tanenbaum (minix@cs.vu.nl)
