I must apologize for my confusion of the model number which was Chinon's
CDA-535 (not CDS) for MacIntosh.  The Snoy's CDU-561 was also slod as for
Mac.  So, I may be encountering a conflict between CDROMs for Mac and for
PC.   Is it right?

PS.  Chinon's CDS-431 is for PC, which is now functioning by your advice.
