Little Board/P5x Technical Manual

Setup 5 — Power Management Setup

The Little Board/P5x CPU BIOS incorporates power management features compliant with Advanced Power Management (APM) BIOS Interface Specification Revision 1.1, created by Intel and Microsoft. Setup 5 — Power Management Setup allows you to configure your system to most effectively save energy while operating at the speed and response level you need in your application. Figure 2– 10 shows what can be configured on Setup 5. A description of each option is listed below.

Note

When features of the APM BIOS are enabled, some reduced power states are entered automatically. Reduced power states alter the performance of the system, usually slowing or halting the CPU. Use the power management functions with care when using the Little Board in applications that require guaranteed maximum response times.
