Chapter 2 AMI BIOS Setup
2.4.7 APM Configuration
Figure 2.11 APM configuration
APM allows the BIOS to control the system’s power management without the knowl-
edge of the operating system. The default setting for “Power Management/APM” is
“Enabled”.
! Hard Disk Power Down Mode: Used to power down the hard disk drive in
“Suspend” mode. The default setting for this feature is “Disabled”.
! Throttle Slow Clock Ratio: Used to select the duty cycle of the CPU in throttle
mode. The default setting for this feature is “50%”.
! Keyboard & PS/2 Mouse: Allows the system to monitor KBC Ports 60/6.
Note! When both ACPI and APM modes are enabled at the same time on the
BIOS setup, the former power management control will take precedence
if the OS supports ACPI mode. In the event that the OS is unaware of
ACPI, APM will take control.
