Enhancing Performance in DOS and Windows
The following two procedures can enhance CD-ROM drive performance.
The CDSETUP program disables the cache CD-ROM data function.
Multisession CDs are not compatible with the SMARTDRV caching method.
If you do not plan to use PhotoCD or multisession CDs, you can enable caching by removing
the /U parameter from the SMARTDRV line in the AUTOEXEC.BAT or CONFIG.SYS file.
This might improve the performance of some CD-ROM applications.
You must have SMARTDRV 5.0 or later to cache CD-ROM data.
