We haven't thought so much about boot yet; we are using old BSD boot
routines so far. What is thought is that there would be the same thing
in sectors 0-15 on whatever vax or disk you are using, as it is under
Ultrix. BSD uses different files for each disk type and that is not 
good at all. If you want to mix with the boot routines it would be good;
we are currently using 2*11/750 here for developing.
Bertram Barth is also looking at boot, but i think he is rather busy right
now. If you want to work with boot routines just tell me and I will
note you for that.
