Restore on AC Power Loss
Use this feature to set the power state after a power outage. Select Power-Off for
the system power to remain off after a power loss. Select Power-On for the system
power to be turned on after a power loss. Select Last State to allow the system to
resume its last state before a power loss. The options are Power-On, Power-Off
and Last State.
Interrupt 19 Capture
Interrupt 19 is the software interrupt that handles the boot disk function. When this
item is set to Enabled, the ROM BIOS of the host adaptors will "capture" Interrupt
19 at boot and allow the drives that are attached to these host adaptors to function
as bootable disks. If this item is set to Disabled, the ROM BIOS of the host adap-
tors will not capture Interrupt 19, and the drives attached to these adaptors will not
function as bootable devices. The options are Enabled and Disabled.
Processor and Clock Options
This submenu allows the user to confi gure the Processor and Clock settings.
CPU Ratio
If set to Manual, this option allows the user to set the ratio between the CPU Core
Clock and the System Bus Frequency. (Note: if an invalid ratio is entered, the
AMI BIOS will restore the setting to the previous state.) The options are Auto and
Manual.
Clock Spread Spectrum
Select Enable to use the feature of Clock Spectrum, which will allow the BIOS to
monitor and attempt to reduce the level of Electromagnetic Interference caused by
the components whenever needed. The options are Disabled and Enabled.
Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware pre fetcher will pre fetch streams of data and instruc-
tions from the main memory to the L2 cache in the forward or backward manner to
improve CPU performance. The options are Disabled and Enabled.
Adjacent Cache Line Prefetch (Available when supported by the CPU)
The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The
CPU fetches both cache lines for 128 bytes as comprised if Enabled.
Intel® Virtualization Technology (Available when supported by the CPU)
Select Enabled to use the feature of Virtualization Technology to allow one platform
to run multiple operating systems and applications in independent partitions, creat-
ing multiple "virtual" systems in one physical computer. The options are Enabled
