Interactive Unix attempts to hide its "unixness" under a primitive menu system, much resembling the idea of "linuxconf". Unlike Linux though, the developers have gone to great lengths making it virtually impossible to go beyond the menu system and do things manually. And all source code is encrypted so you can't fix it either.
Reconfigure, build and install kernels: kconfig
Reconfigure other stuff: sysadm
Shut down immediately: shutdown -y -g0
Locate files: find / -name -print
Routes to other networks: /etc/gateways
Manual network configuration: /etc/netd.cf
Change to runlevel 2 (multiuser) is handled by /etc/rc2
It calls the following: (in this particular order)
/etc/rc2.d/K* stop
/etc/rc2.d/S* start
/etc/idrc.d/*
/etc/rc.d/*
Recommended network adapter:
Western Digital WD8003EP soft configured using SMC EZSTART
Device: wd0 Port: 300 IRQ: 3 Base: D8000-DBFFF
Good luck!
