For every computer enthusiast, we are very concerned about the reading and writing speed of the optical drive, especially when we are installing software. Replacing a better-performance optical drive is our goal forever, but due to the lack of cash, adding cache to the optical drive is an effective way to improve the read and write speed of the existing optical drive. Since Windows 98 recommends using a four-speed or higher optical drive access method, it is not in line with the currently popular optical drives. In order to adapt to the popular optical drives with a speed of 16 times higher than today, we can improve the size and pre-read performance of the optical drive by modifying the registry to speed up the operation speed of the optical drive and put the optical drive performance to the limit.
1. Open the Registry Editor (Start → Run → Regedit);
2. Find the "HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETCONTROLFILESYSTEMCDFS" branch;
3. Find the two items CACHESIZE and PREFETCH in the window on the right of this item. If you choose the four-speed or higher-speed optical drive access method recommended by Windows 98, the values of these two items are "6B020000" and "E4000000" respectively. At this time, we can modify it based on the actual usage of our own optical drive. If the optical drive is often used for multimedia playback, you can change the CACHESIZE value to "D6040000", and "AC090000" is the maximum value of the optical drive cache. In order to ensure the consistent speed of high-speed optical drives, the PREFETCH value can be modified, such as the 8-speed speed is "C0010000", the 16-speed speed is "80030000", the 24-speed speed is "40050000", and the 32-speed speed is "00070000".
Note: If the two key values are modified, the optical drive cannot work normally. If the VCD cannot be played normally, please lower the value of one level.
After completion, exit the Registry Editor and restart the computer.
