I was looking for 6 hour on net for this driver. It is sorry that Sony does not have it on his main page. Found on Sony-Europe, at last.
Think that it is the first step driver for DOS to install CDU4821 CD-ROM.
Didnt try it, but will this evening.
The following files are found inside the driver download file.
