What is Smapi BIOS?, System Information, Power Management | IBM 560

What is SMAPI BIOS?

The ThinkPad Basic Input/Output System (BIOS) provides a special software interface, called the System Management Application Program Interface (SMAPI) BIOS, to control the following unique features of the ThinkPad system:

System Information

This BIOS provides unique ThinkPad information, such as the system identifier (system ID).

System Configuration

The ThinkPad SMAPI BIOS provides system configuration

control for such features as display device selection or resource configuration for built-in devices.

Power Management

Through the SMAPI BIOS, the operating system or application software can control the ThinkPad power management features (the Power mode or Suspend/Hibernation/Resume options).

“Header Image” on page A-4 describes how to use the SMAPI BIOS.
