Shut down the IIci and remove the battery to erase the PRAM. Give if a half hour or so for the PRAM to die out. Out the battery back in.
Turn on the Mac IIci while holding command-option-P and R to reset the PRAM. It will BONG again and again until after you let go of the buttons. I let it bong 3 times but one (2- the boot up and 1 more for PRAM reset) is only needed. After you get go of the keys, hold down the left Shift Key to boot with the Extensions off.
That should get your Mac IIci running again. When it is, go into the system folder and delete that damn Inventory extension and empty the trash. Search the system for preferences and control panels that goes with it, along with the hard drive with any app or data, and trash them all.
If it still does not boot, you are going to need to boot from a floppy, as that Inventory program corrupted your system file. It may not be a virus, but there were some programs that screwed up the system in a bad way. Norton for System 6 was like this for any System 7 Macs - it corrupted the system badly. But Norton for System 7 was fine for System 6. Go figure.
