Power Management Setup,
Slow Clock Ratio This option specifies the speed at which the system clock runs in power
saving states. The settings are expressed as a ratio between the normal CPU
clock speed and the CPU clock speed when the computer is in the power-
conserving state. The settings are 0-12.5%, 12.5-25%, 25-37.5%, 37.5-50%,
50-62.5%, 62.5-75%, or 75-87.5%. The Optimal and Fail-Safe defaults are
1:8.
Display Activity This option specifies if AMIBIOS is to monitor display activity for power
conservation purposes. When this option is set to Monitor and there is no
display activity for the length of time specified in the Standby Timeout
(Minutes) option, the computer enters a power savings state. The settings are
Monitor or Ignore. The Optimal and Fail-Safe default settings are Ignore.

Device 0 (Primary Master IDE)
Device 1 (Primary Salve IDE)
Device 2 (Secondary Master IDE)
Device 3 (Secondary Slave IDE) When set to Monitor, these options enable event monitoring
on the specified hardware interrupt request line. If set to Monitor and the
computer is in a power saving state, AMIBIOS watches for activity on the
specified IRQ line. The computer enters the Full On state if any activity
occurs. AMIBIOS reloads the Standby and Suspend timeout timers if activity
occurs on the specified IRQ line.
The settings for each of these options are Monitor or Ignore. The Optimal and
Fail-Safe default settings are Ignore.
