BIOS Configuration

Slow Clock Ratio
This option specifies the speed at which the system clock runs in the Standby
Mode power saving state. The settings are expressed as a percentage of the
normal CPU clock speed. 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%.

Display Activity
When set to Monitor, this option enables event monitoring on the video
display. If set to Monitor and the computer is in a power saving state, display
activity will cause the system to enter the Full On state. AMIBIOS reloads the
Standby and Suspend time-out timers if display activity occurs. The settings
are Monitor or Ignore.

Device n (Device identity)
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, any activity on the IRQ line will cause the system to enter
the Full On state. AMIBIOS reloads the Standby and Suspend time-out timers
if activity occurs on the specified IRQ line. The settings for each of these
options are Monitor or Ignore.

LAN Wake-up
When this option is Enabled, the system will wake up when a signal is
received on the Wake-on LAN header. In order for this wake up function to
work, the system must have been brought up at least past the POST before it
was last shut down (i.e. if you turn the system off before the POST, the
registry will not be set, and the system will not be able to wake up using this
function). This function requires an ATX 2.01 compliant power supply with 5V
standby (STB5V) current of at least 800mA. The settings are Enabled or
Disabled.

PC98 Power LED
When this option is Enabled, your power LED will turn to yellow when your
system is in Suspend mode. Note that if you do not have a two-color LED,
your LED will turn off when the system is in Suspend mode if this option is set
to Enabled. The settings are Enabled or Disabled.

FAN OFF at Suspend
If this option is Enabled, the CPU fan will turn off when the system is in
Suspend mode. If Disabled, the CPU fan will remain on while the system is in
Suspend mode. The settings are Enabled or Disabled.
