For every computer enthusiast, the reading and writing speed of the optical drive is of great concern to us, especially when we are installing the software. Replace the better performance of the optical drive is our forever pursuit of the goal, but limited to the pocket, then increase the cache for optical drive is an effective way to improve the reading and writing speed of the existing optical drive, because the Windows 98 recommended to use four times times or more high-speed optical drive access, and the current popular optical drive does not In order to adapt to the current popular 16 times times the speed of optical drive, we can modify the registry to improve the size of the optical drive cache and prefetch performance to speed up the speed of the optical drive, the optical drive performance to the limit.

1. Open Registry Editor (start → run →regedit);

2. Find the "Hkey_local_machinesystemcurrentcontrolsetcontrolfilesystemcdfs" branch;

3. Find the CacheSize and prefetch two items in the right-hand window of the item, if you are selecting the four times-speed or higher-speed optical drive access method recommended by Windows 98, the values are "6b020000" and "E4000000", respectively. At this time we can for the actual use of their own optical drive to modify, if the CD-ROM is often used for multimedia playback, you can change the CacheSize value to "D6040000", "AC090000" is the largest optical drive cache. In order to ensure the high-speed optical drive consistent speed, you can modify the value of prefetch, such as 8 times times the "C0010000", 16 times times the speed of "80030000", 24 times times the "40050000", 32 times times the speed of "00070000".

Note: If you modify the two key values resulting in the optical drive does not work, if the VCD can not play properly, please lower the value of a grade.
