A2.4.1 Two USB ports in all systems, with system BIOS boot support for USB input devices
[SYS-0021, BIOS-0005.2; SDG3:13.3]
If only two USB ports are provided, system provides at least one accessible USB port supporting end user expansion when keyboard and pointing device are attached.
A2.4.2 CD/DVD drive or network adapter (for installing the operating system)
Desktop system includes CD or DVD device.
Note for configure-to-order/build-to-order requirements: PC clients shipped into retail markets must have at least the minimum hardware support that is listed in these requirements. Retail markets include:
Retail “on-shelf” configurations.
A default configure-to-order or build-to-order system configuration.
It is recognized that OEMs may configure PC systems to meet the requirements of a specific end-user or corporate customer. For systems built based on specific customer requests, where customers request systems without either a CD or DVD optical drive, the system may be configured without an optical storage drive. However, the system must support the addition of a CD or DVD optical drive, and the system firmware must support booting from a CD or DVD device using El Torito Version 1.0 No Emulation Mode if a supporting optical drive is added.
Furthermore, systems may be configured on request without a graphics adapter or network adapter. All retail market desktop systems must include a graphics adapter and must support installation of an operating system by including either a CD/DVD drive or network adapter. [see A1.4.3, A1.1.4]
This section describes additional requirements or exceptions to the requirements defined earlier in Section A1.0.
A3.0.1 General System Exceptions for Mobile PCs

A3.0.2 Legacy-free System Exceptions for Mobile PCs
The following exceptions to Legacy-Free PC System requirements are also defined for Mobile PC systems in elsewhere Appendix A:
A4.1.3 No components claim to use the restricted port addresses – mobile exceptions:
Both desktop and mobile PCs can use the 8042 controller internally, but must not include external PS/2 connectors. Legacy-free systems that use the 8042 controller internally must set the 8042 flag to 1 in the ACPI FADT.
Systems can provide Super I/O-based Infrared Data Association (IrDA) support through the year 2001.
A4.4.2 A mobile PC is required to provide only one free USB port.
A4.4.8 MS-DOS must not be required to install or run any utilities, games, or other software provided with the system -- required for new docking stations designed for legacy-free mobile PCs.
A4.5.3 CD or DVD drive requirement – exceptions for legacy-free mobile PCs.

A3.4.1 Power and power management requirements
[SYS-0002 ; MOBL-0062]
Every device in a mobile PC system functions fully on both AC and DC power.
[see FAQ A3.5.8]
Mobile system implements either S1 or S3, S4, and S5 sleep states (no "wake from S3 or S4" requirement). [SYS-0002.1]
Smart Battery or ACPI Control Method Battery. [MOBL-0062; see FAQ A3.5.8]
Smart Battery systems that support battery calibration must use the Smart Battery System Manager optional calibrate support bits in the BatterySystemStateCont register. [MOBL-0062.1]
Windows XP: Systems implementing processor performance states must use native Windows support. This means that all performance policy and switching must be done by the operating system. See "Windows XP Native Processor Performance Control" whitepaper at http://www.microsoft.com/hwdev/onnow/.
A3.4.2 BIOS requirements
Support for external pointing device. [MOBL-0066; see FAQ A3.5.3]
Support PXE if system includes integrated network adapter. [BIOS-0014.1; see FAQ A3.5.7]
A3.4.3 Connector icons on back of case, wrapped to the bottom of the unit, or placed inside an access door
Docked mobile PC meets Mobile PC system and BIOS requirements. [MOBL-0074, MOBL-0076]
Docked mobile PC can uniquely identify the dock. [MOBL-0073]
Docking station supports warm docking and fail-safe docking. [MOBL-0079; MOBL-0080]
Enumerate, configure, and disable non-Plug and Play devices using ACPI-based methods. [MOBL-0078]
Docked mobile PC meets BIOS requirement for multiple adapters and multiple monitors. [MOBL-0076]
Docked mobile PC allows user speaker selection. [AUD-0339; see also FAQ A3.5.9]

A3.5.1 Current general FAQs
A3.5.2 Manageability requirements [Clarification]
Current SMBIOS requirements are defined in A1.1.4.
FAQ Date: May 4, 2000
A3.5.3 BIOS support of external pointing device [Clarification]
The required default BIOS option is to provide an option to disable the internal pointing device when any external PS/2-type pointing device is detected at startup. In this case, the driver for the internal pointing device must not load.
FAQ date: October 7, 1998
A3.5.4 DDC monitor detection [Clarification]
Because of the power limitations placed on mobile computers, they are not required to supply 5V power via the external graphics adapter as is currently required by the VESA DDC specification.
Some display devices rely on the 5 V to power their DDC circuitry, for Plug and Play detection, or both. It is recommended that a mobile PC provide a means to enable the 5 V power when necessary.

A3.5.5 ICC profile for mobile PCs [Clarification]
Current requirements are defined at B220.127.116.11; design guidelines are provided in PC 2001. [MON-0235]
A3.5.7 BIOS support for PXE [Clarification]
Current requirements are defined in A1.1.4.
A3.5.8 Battery power requirements [Clarification]
Every device in a mobile PC system should function fully on both AC and DC power. It is not acceptable for hardware or system firmware to autonomously disable, remove, or force power down of devices on an AC > DC transition. This can cause situations that result in the system shutting down, lost data, operating system failure of subsequent power management events, or at the least, warning messages displayed to the user. Internal devices must only be powered down, disabled, or removed when commanded to do so by the operating system and device drivers in accordance with bus and device power management specifications.
This clarification does not require port replicators or docking stations to operate on battery power.
It is not required that a mobile/docking station pair implement audio. The following provides a clarification to the requirement:
The user must be able to select speakers in the mobile unit or the docking station. System vendors can choose to automate the process either in the docking station or the mobile PC to meet this requirement. For example, instead of offering a UI where the user can select speakers, the system manufacturer can configure the pair to automatically turn on the docking station speakers and turn off the mobile PC speakers when in the docked configuration.
This requirement is defined to ensure that users can access the highest quality audio output in any given configuration. If speakers are selected automatically, the vendor should prevent multiple outputs from occurring simultaneously. If speakers are not selected automatically, then a manual selection process must be offered to the user. Additionally, the speakers should be switched off if the headphone or line-out jacks are used.
