Corrupted rc.config file

i used yast2 to change a couple settings (turned off apm and isapnp) on my suse 7.1 pro box and now it won't boot. i get the error: /etc/init.d/boot: .: /etc/rc.config: cannot execute binary file and the boot process stops after mounting the /proc and /dev/pts filesystems. the machine is not hung (i can type to my hearts content, but it accomplishes nothing) but cannot complete the boot process. does anyone know a way around this so i can restore my old rc.config file? thanks --trey
