Windows 98 SE and Intel SpeedStep Technology

Use the Intel SpeedStep technology (available in systems with Intel Pentium III processors) to optimize processing speed and conserve battery life.

Enable Intel SpeedStep technology through the Power menu (Intel SpeedStep2) in the BIOS Setup utility. The available settings are Disabled and Enabled. Use Disabled to turn off Intel SpeedStep2 technology.

If Intel SpeedStep2 technology is enabled in your system, an icon appears on your taskbar allowing you to adjust processing properties. However, the default settings are recommended for optimal performance and battery conservation.

For information about accessing the BIOS Setup utility and the Intel SpeedStep2 technology parameter, see “Entering BIOS Setup” and “Power Menu” earlier in this chapter.
