first it doesn't have to reinstall system;
second, it does need to boot into single user mode through cdrom or net.
most experts recommend the way below; some others say copying /dev and /devices from cdrom to /a at single mode. but the "cp" command doesn't copy character devices rightly when I tried.
anyway, the way below is simple and effective .

	Boot from a CD using "boot cdrom -s"
	Mount your root partition under /a
	Rename /a/etc/path_to_inst as /a/etc/path_to_inst_saved
	Do driver reconfigurations on the machine's real root:
		drvconfig -n -r /a
	Touch /a/reconfigure
	Sync and umount /a
	Abort the running kernel using Stop-A
	Reboot using "boot -svra"
		Single user
		Verbose (always nice to see everything
		Ask Me
	At the AskMe prompts, take the defaults.  If the system hangs on bootup
	you will at least know what file is giving you trouble and you can try
	to set up a new version of the offending configs using the CDROM.

If you are successful at rebooting the machine into single-user mode, I suggest 
that you "reboot -- -svr" back into single-user to make sure there are no 
problems.  Then, you should be OK to boot into normal mode.
