Put another way, I can boot CD's, but not the hard drive. Was running os9.2.2, and had to Force Quit a game, Marathon 2, and this caused the Finder screen to blank, with no icons, the control strip, or menubar, and a funny-looking spot on the screen where the mouse cursor lay. Nothing happened after a few seconds, so I did a ctrl-command-powerSwitch. Heard the chime, then a ker-chunk noise from the hard drive, the screen flashed light-blue, black, turned grey and the folder icon with flashing Mac icon alternating with a flashing question mark was seen. Tried holding down the X key at boot up (it's supposed to start-up in osX if one was originally in os9), but nothing changed. Put the Jaguar CD in, only to find I need to erase 500mb or so of stuff just to reinstall just the os... 'cept I can't, you see, as that requires booting. HELP!!!
