Like the tools in /usr/local. It is going to be a while until I have a kernel which works well enough to boot on a real machine. For instance, my 'kernel' (snigger) has no devices or bus code in it at all :-). I plan to use SimOS for early kernel bootstrapping and think about booting it on a physical machine much later. SimOS is very nice; it simulates the alpha accurately enough to boot Digital Unix and has a tcl interface for instrumenting and debugging. Unfortunately, it would be hard (if not impossible) to host SimOS on an i386. I am running it under Linux/alpha for now. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
