I noticed that in imgact_aout.c the text segment gets mapped starting at linear address 4096. Is it possible to map the first page of linear memory? What I would like to be able to do is set up a process in which linear addresses starting at 0 are mapped. When I modified imgact_aout.c to map the first linear page of memory as an experiment, and then ran a specially cooked executable to exercise that code, the machine immediately hung. Is there something special on the first linear page of a user process? Thanks, Greg Johnson johnson@nrtc.northrop.com
