DOS Drivers (EIDE/ATAPI Drives)
This driver supports Sony ATAPI CD-ROM, CD-RW, and DVD-ROM drives as a reader
device under MS DOS only. This driver is useful for use on a BOOT disk to
install/re-install an operating system, where bootable CD's can not be used.
NOTE Windows operating systems have built in drivers to support your Sony
CD-ROM, CD-RW, DVD-ROM drive as a CD-ROM reader. No additional drivers are
normally required once Windows is installed and running. However, you will
need additional software to make use of CD Writing and DVD Video playback
if your drive supports these functions.
