Suggested solutions

6When Windows 9x loads, open WINDOWS EXPLORER and see if you can find the DVD-ROM drive. In the example described here the DVD- ROM drive should appear as drive letter D:. (Because there is only one hard disk (C:) and we are assuming that it is not partitioned); If your hard disk has been partitioned or if you have multiple hard disks, the DVD- ROM drive will generally be the highest assigned drive letter.

You may wish to insert a regular CD-ROM disk into the DVD-ROM drive and ensure that you can read it by browsing with WINDOWS EXPLORER. (An ATI installation CD may be used for this step) If the CD- ROM auto launches then you know that the DVD-ROM drive is installed properly and working.

If you continue to experience difficulties:

If you continue to experience difficulties using the DVD-ROM drive, particularly when playing DVD movies, there are a few things, listed below, to consider. Even if you don't understand the concepts described below, you should do your best to investigate and document any information you can before calling for technical support.

•Systems that have the port driver Mkeatapi.mpd v.2.01 installed for the hard disk controller may experience problems. If your system has this driver installed and you are experiencing difficulties, upgrade this driver.

•Real mode CD-ROM drivers may interfere with proper DVD-ROM operation. Look in the CONFIG.SYS file for CD-ROM drivers that may be loaded. Real mode drivers for the CD-ROM are only required if you wish to access the CD-ROM from DOS. Your emergency boot diskette should be configured with real mode CD-ROM drivers. But these drivers should not usually be required for normal operation in Windows 9X.

•DVD-ROM drives that were originally connected to a special hardware DVD decoder board may only work with that board and with special drivers.

•Older DVD-ROM drives may experience performance issues and/or may require a firmware revision (consult the DVD manufacturer) for correct operation. A second generation or newer DVD-ROM drive is recommended for the best results.

•If you have installed more than one DVD movie solution it is possible that they will interfere with each other. It is quite possible for multiple DVD solutions to co-exist and even run simultaneously, however; if you are having problems it is best to focus on only one application at a time and also give that application the cleanest environment possible.
