Retail markets include:
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.

A3.4.2 BIOS requirements
A3.4.3 Connector icons on back of case, wrapped to the bottom of the unit, or placed inside an access doorColor-coding is not required. A3.4.4 Mobile system contains required devices and buses[MOBL-006x]
2-D hardware acceleration, 640 × 480, low-resolution modes. [GRPH-0393.1] If 3-D is supported, 640 × 480 × 16 bpp; no minimum texture cache, alpha blending, hardware text mapping requirements. [GRPH-0393.3, 0393.4] No multiple adapter support required in mobile unit; multiple monitor support is optional.

For systems supporting 3-D graphics hardware, performance equivalent of AGP 1x with GART is required. [GRPH-0393.2] International Color Consortium (ICC) color profile and INF preinstalled if DDC detection cannot be used.

A3.4.8 DELETEDA3.4.9 If mobile supports a docking station, mobile unit’s BIOS supports docking-related ACPI functions[MOBL-0078] A3.4.10 If IEEE 1394 is included in a system, at least one externally-accessible socket is required[MOBL-0064] A3.5 Mobile PC Client - FAQsA3.5.1 Current general FAQsSee http://www.microsoft.com/winlogo/hardware/system/. 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][MOBL-0066] 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][GRPH-0393.6] 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 B4.2.4.2; design guidelines are provided in PC 2001. [MON-0235] A3.5.6 DELETEDA3.5.7 BIOS support for PXE [Clarification][BIOS-0014.1] 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. FAQ date: May 28, 1999 A3.5.9 Docking station/mobile audio [Clarification]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. FAQ date: December 22, 1998 A3.5.10 DELETEDFAQ date: January 31, 2001 A3.5.11 Docking Station and Port Replicator Definitions [Clarification]Port Replicator: For the purposes of the Windows Logo Program, a Port Replicator physically mates to the Mobile PC and is an acceptable method for adding the following functionality to a mobile PC. All of the following features must be compliant with their respective Windows Logo Program requirements, specifications, and standards:
Audio, including line-in, line-out, microphone, and headphone DVI Floppy drive Game port IEEE 1394 PHY LAN MIDI port Modem Parallel or LPT port PS/2 port Serial port USB connector: pass-through connector is allowed to be low power Video Any bus used exclusively for manageability Docking Station: For the purposes of the Windows Logo Program, a Docking Station connects to the mobile PC’s PCI bus and includes the functionality of a Port Replicator plus additional expansion in the form of Plug and Play-enumerable devices or slots.
