I'll try to shorten the story, the system cdrom stopped working after 26 mos of service. Using Win98 opsys, old cdrom was OEM "AOpen" mod# CD-93E/AKW. Purchased a Sony mod# CDU5211 (it is OEM) nothing extra except for the plastic bag the drive was packaged in. (no drivers or info). I hooked it up, powered the Computer back up and needless to say the new CDU does not work, windokws told me that it needed a driver titled "SZLCD32.MPD", it was not in the system nor on the win98 CD (Iwas able to use the HPcdrw for reading at that time). I browsed around the net and finall located the specified driver, downloaded it, put it on a floppy and feed to win98 when it requested it. win98 is still not happy as it tell's me on the Device Manager page - CD-ROM Controllers - "Sony Proprietary CD-ROM Controller- Device status "This device is either not present, not working properly or does not have all the drivers installed (Code 10) - - Try updating the drivers for this device", which I tried again, but of course nothing else ids available for it - Something to the effect that the best driver is already loaded. "The location of the driver C:\Windows\InI\Adapter.Ini.. ???? I really need some help on what to do next, - ?? My PC skill level is somewhere between between a Novice and simi-experienced.. PS along the way I lost the HP CDRW but I'm not sweating that as I have a CD to get it back into the system - if ONLY I had a working system CDROM. Thanks to anyone who can help me on this. Mac
