	It's 1X speed (what else would the reference speed mean? ;-).

	Incidentally, you should be wary of 1X, 2X, 4X, (6X?) IDE
	CD-ROMs because these are older and less likely to
	conform to the ATAPI standard - hence more likely to have
	compatability issues ... OTOH, if you use the _correct_
	driver, you will _often_ have no trouble from these older
	drives ...

	Uhhh - last time I checked, ATAPI drives are always *disabled*
	in the BIOS "CMOS settings" ... however, I have not played
	around much with ATAPI-aware BIOSes so, perhaps there are
	now some ATAPI-specific BIOS settings that I am not aware
	of. Nevertheless, a "disabled" setting for your ATAPI drives is
	*always* appropriate and your safest option ...

	Also, if you have a single drive on an IDE cable, you should
	always set this as master. Sure, sometimes a "slave" setting
	may work, but usually it doesn't work or causes trouble.
	Similarly, if there are two drives, one must be set as master,
	the other as slave.
