Hardware Prefetcher: [Disabled]
A third mechanism used to reduce the time waiting for DRAM is through a
hardware-prefetching scheme. The hardware prefetcher looks for streams of data
and tries to predict what data will be needed next by the processor and proactively
tries to fetch these data. All Intel Pentium 4 processors contain a hardware
prefetcher that can prefetch both code and data streams, where the data stream
can be accessed by loads and/or stores.
Adjacent Cache Line Prefetch [Disabled]
This menu allows you to enable or disable the adjacent cache line prefetch mode.
Configuration options: [Disabled] [Enabled]
Hyper-Threading Technology [Enabled]
This item allows you to enable or disable the processor Hyper-Threading Technology.
This technology allows a single processor supporting Hyper-Threading Technology
presents itself to modern operating systems and applications as two virtual
processors. The processor can work on two sets of tasks simultaneously; use
resources that otherwise would sit idle, and get more work done in the same
amount of time.
Configuration options: [Disabled] [Enabled]
IDE Configuration
The items in this menu allow you to set or change the configurations for the IDE
devices installed in the system. Select an item then press Enter if you wish to
configure the item.
ATA/IDE Configuration [Compatible]
This item allows you to configure the ATA/IDE.

Legacy IDE Channels [SATA Pri, PATA Sec]
Primary and Secondary IDE Master/Slave
While CPEX series is turned ON, the BIOS auto detects the presence of IDE devices.
This menu, when entered, shows detail information of the IDE devices (Device type,
Vendor, Size, LBA Mode, Block Mode, PIO Mode, Async DMA, Ultra DMA, and SMART
monitoring). This information is auto-detected by BIOS and is not user-configurable.
It will show "Not Detected” if no IDE device is installed in the system.
