computer is configured to use DVMT, graphics memory is allocated based on system
requirements and application demands (up to the configured maximum amount). When memory
is no longer needed by an application, the dynamically allocated portion of memory is returned to
the operating system for other uses.

1.11 Power Management
Power management is implemented at several levels, including:
• Software support through Advanced Configuration and Power Interface (ACPI)
• Hardware support:
Power Input
Instantly Available PC technology
1.11.1 ACPI
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. The use of ACPI with the Intel Compute Stick requires an operating
system that provides full ACPI support. ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices
Table 3 lists the system states based on how long the power switch is pressed, depending on how
ACPI is configured with an ACPI-aware operating system.

1.11.1.1 System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The
operating system puts devices in and out of low-power states based on user preferences and
knowledge of how devices are being used by applications. Devices that are not being used can be
turned off. The operating system uses information from applications and user settings to put the
system as a whole into a low-power state.
Table 4 lists the power states supported by the Intel Compute Stick along with the associated
system power targets. See the ACPI specification for a complete description of the various system
and power states.

• Wake from Power Button signal
• Instantly Available PC technology
1.11.2.1 Power Input
When resuming from an AC power failure, the Intel Compute Stick may return to the power state it
was in before power was interrupted (on or off). The Intel Compute Stick’s response can be set
using the Last Power State feature in the BIOS Setup program’s Boot menu.
1.11.2.2 Intel® Virtualization Technology
Intel Virtualization Technology (Intel VT) is a hardware-assisted technology that, when
combined with software-based virtualization solutions, provides maximum system utilization by
consolidating multiple environments into a single server or client.
NOTE
A processor with Intel VT does not guarantee that virtualization will work on the Intel Compute
Stick. Intel VT requires enabling software and/or operating system, device drivers, and
applications designed for this feature.

2 Technical Reference
2.1 Memory Resources
2.1.1 Addressable Memory
The Intel Compute Stick utilizes up to 4 GB of addressable system memory. Typically the address
space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space,
BIOS (SPI Flash device), and chipset overhead resides above the top of DRAM (total system
memory). On a system that has 8 GB of system memory installed, it is not possible to use all of
the installed memory due to system address space being allocated for other system critical
functions. These functions include the following:
• BIOS/SPI Flash device (64 Mbit)
• Local APIC (19 MB)
• Direct Media Interface (40 MB)
• PCI Express configuration space (256 MB)
• SoC base address registers PCI Express ports (up to 256 MB)
• Integrated graphics shared memory (up to 512 MB; 64 MB by default)
The Intel Compute Stick provides the capability to reclaim the physical memory overlapped by the
memory mapped I/O logical address space. Physical memory is remapped from the top of usable
DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just
above the 4 GB boundary. All installed system memory can be used when there is no overlap of
system addresses.

3 Overview of BIOS Features
3.1 Introduction
The Intel Compute Stick uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash
Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the
BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The
initial production BIOSs are identified as FCBYT10H.86A.
The BIOS Setup program can be used to view and change the BIOS settings for the computer, and
to update the system BIOS. The BIOS Setup program is accessed by pressing the <F2> key after
the Power-On Self-Test (POST) memory test begins and before the operating system boot begins.
3.2 BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb (8192 KB) flash
memory.
3.3 System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a
managed network.
The main component of SMBIOS is the Management Information Format (MIF) database, which
contains information about the computing system and its components. Using SMBIOS, a system
administrator can obtain the system types, capabilities, operational status, and installation dates
for system components. The MIF database defines the data and provides the method for
accessing this information. The BIOS enables applications such as third-party management
software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:
• BIOS data, such as the BIOS revision level
• Fixed-system data, such as peripherals, serial numbers, and asset tags
• Resource data, such as memory size, cache size, and processor speed
• Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS
information. The BIOS supports an SMBIOS table interface for such operating systems. Using this
support, an SMBIOS service-level application running on a non-Plug and Play operating system
can obtain the SMBIOS information. Additional information can be found in the BIOS under the
Additional Information header under the Main BIOS page.

22
3.4 BIOS Updates
The BIOS can be updated using either of the following utilities, which are available on the Intel
World Wide Web site:
• Intel® Flash Memory Update Utility, which requires booting from DOS. Using this utility, the
BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive),
or a CD-ROM.
• Intel F7 switch during POST allows a user to select where the BIOS .bio file is located and
perform the update from that location/device.
All utilities verify that the updated BIOS matches the target system to prevent accidentally
installing an incompatible BIOS.

3.6 Boot Options
In the BIOS Setup program, the user can choose to boot from local storage or a removable drive.
The default setting is for the local storage to be the first boot device.
3.6.1 Booting Without Attached Devices.
For use in embedded applications, the BIOS has been designed so that after passing the POST,
the operating system loader is invoked even if the following devices are not present:
• Video Display
• Keyboard
• Mouse
3.6.2 Changing the Default Boot Device During POST
Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu
displays the list of available boot devices. Table 8 lists the boot device menu options.
Table 8. Boot Device Menu Options
Boot Device Menu Function Keys Description
<
↑
> or <
↓
> Selects a default boot device
<Enter> Exits the menu, and boots from the selected device
<Esc> Exits the menu and boots according to the boot priority defined
through BIOS setup
3.6.3 Power Button Menu
The Power Button Menu is accessible via the following sequence:
1. System is in S5 (not G3)
2. User pushes the power button and holds it down for approximately 3 seconds
3. Release immediately
4. User releases the power button before the 4-second shutdown override
If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where
possible.
At the point where Setup Entry/Boot would be in the normal boot path, the BIOS will display the
following prompt and wait for a keystroke:
[ESC] Normal Boot
[F2] Intel BIOS
[F4] BIOS Recovery
[F7] Update BIOS
[F8] Operating System Recovery
[F10] Enter Boot Menu
