Hi,
to answer a question what do you do if the booting does not work ?
i.e., if you want to modify the scripts in /etc/init.d without boouting the
tape
The soulution is a hacker solution which proved to work on 4D/70,80,and 120.
It shows that once you have access to the console and a software tape on hand,
you get into *any* 4D without providing any password.
1) go to >> prompt (old PROM versions)
2) start the installer
3) manual installation
4) administrative
5) spawn a shell and look into /root/
There, you will find /root/etc/init.d, and you might want to copy original
SGI scripts from /etc/init.d
Nasty thing: You say
cp /etc/passwd /root/etc/passwd
and reboot the machine.
root doesn't have a password no longer !!!
