	I am having trouble with my hard disk. About once a week it
	disappears. I get the "?" MAC at startup. I then have to boot
	with a floppy disk, go to the control Panel (with COMMAND-OPTION-
	SHIFT) to reset the PRAM. And finally (get this) shut down, UNPLUG
	my MAC and press the Power On button. This seems to discharge the
	CMOS?! Then I can reboot and my hard disk is there. 

		I have an original MAC II with a CMS Pro 60-i.
		PLEASE HELP!!!!

	Thank Ya - Thank Ya!
