Zap your PRAM by holding down the command-option-p-r keys at startup. Keep them down until youve heard the startup chime for the third time. If that fails, boot off your system CD and install a fresh system folder to boot from.

Or, try booting without system extensions: hold down the shift button while booting until the message appears "system extensions deactivated", or whatever it is in English (sorry, I only have German systems). This is worth trying before you redo everything or zap your settings.

Also post the machine specs including the hard drive type, capacity and model.  How much physical RAM do you have?  How many hard drives on what interface (SCSI, IDE)?  If you know your system revision it can help us.  

You stated that you disabled VM...did you install new software just before this.  If so, richiejune's suspicion of extension conflict is probably on the ball.

Other possibilities, your PRAM battery is dead.  This can cause more problems than people think.  

If it's a B&W g3, you may have a revision 1 board with the bad IDE controller.  If a beige g3, perhaps a bad ROM module.

In any case, data is required.

Insert OS 9 cd in your tray
Restart and hold down "C" at startup chime, keep holding c
This will boot you to the cd.
In the utilities folder of the cd you will see DFA, repair your disk using DFA.

If it doesnt work, do a reinstall of 9, just reinstallation, you will not lose or affect anything.

reboot. hold shift until you see "Extensions Disabled"..I think..then go into your memory control panel, turn virtual memory on/off, whichever it isn't. if you're turning it on, you may need to set it to a decent chunk, I usually just set mine to 500, just so I wouldn't run out (I have a 40 gig HD though).

reboot, don't hold shift. if this doesn't work, reset your PRAM with weed's method. you may have to try this a few times.

you have to hit the keys and hold until you hear the chime, and you have to do it before it starts too much loading.

ok....weed is right....you dont need many system specs to fix this problem its pretty simple...boot off your  system CD....return virtual memory to its former position and restart....simple....easy.... or resetting the PRAM would have almost the same effect..
