See 'Design Guidelines for PC Card and CardBus' at http://www.microsoft.com/hwdev/platform/pcdesign/desguide/default.asp.

B2.1.4.1 Controller complies with industry standards and Windows-compatible configuration

B2.1.4.1 Exchangeable Card Architecture register set.

The built-in software supporting 16-bit PC Card cards in Windows includes drivers for the industry-standard Exchangeable Card Architecture-compatible (ExCA-compatible) socket controllers. To be compatible with these drivers, socket-controller implementations must support the industry-standard ExCA base register set.

Notice that some controllers do not fully implement the register set and therefore are incompatible. Also, some controllers implement extended registers or enhancements. The built-in Windows drivers do not exploit these features, even though the controller might be compatible.

B2.1.4.2 CardBus bridges.

Systems must support the definition in PC Card Standard Release 7 (or later) PC Card Host System Specification (Volume 11), PCI-to-CardBus Bridge Register Description (Section 4) for CardBus controllers (PCI-to-CardBus bridges). This definition includes a common PCI Configuration Space header assigned the Header Type field value of 82h.

Windows supports this specification. Any controller features that are not part of this specification will not be used in standard drivers. The BIOS is responsible for any hardware initialization or setup required to make the controller comply with this specification or other requirements in this document.

Because CardBus host controllers are PCI bus bridges, they will be supported (enumerated and configured) by the PCI software in Windows in the same manner as other PCI bus bridges.

PCCard-3 in 'PC Card and CardBus Guidelines' Version 1.1, is incorrect; it should also list header type 02h in addition to type 82h, which is listed as an acceptable header type for CardBus bridges.

B2.1.4.3 ISA and PCI interrupts.

PC Card software dynamically configures the bridge to use ISA interrupts for 16-bit PC Card cards and to use PCI interrupts for CardBus cards. CardBus controllers must maintain mapping of IRQ routing. Also, notice that systems implementing CardBus controllers must fully support PCI 2.2 as well as additional PCI requirements for IRQ routing.

To ensure that Windows system correctly assign ISA IRQs to 16-bit PC Cards, A CardBus controller with parallel ISA IRQ mode must have all ISA IRQs pins, except IRQ 0 (timer), 1 (keyboard), 6 (floppy), 8 (CMOS), and 13 (math coprocessor).

It is recommended that system vendors using parallel ISA IRQ mode always connect ISA IRQs 3, 4, 5, 7, 9, 10, 11, 12, 14, 15 and not cross wire them.

For vendors using serialized IRQ mode, the above is not relevant because they only need to connect the serial IRQ pin, and the ISA IRQ information will be sent to the PCI chip set serially; the ISA IRQ information can specify any of IRQ 0-15.

B2.1.4.4 See A3.4.4.5

B2.1.4.5 See A3.4.4.5

B2.1.4.2 CardBus cards are configured correctly

Required tuples are defined in PCCard-14 through PCCard-16 in 'Design Guidelines for PC Card and CardBus, Version 1.1'

B2.1.4.3 16-bit PC Cards are configured correctly; driver supports sharing of level-mode interrupts

For complete requirements, see PCCard-11 through PCCard-13 in 'Design Guidelines for PC Card and CardBus, Version 1.1'

CardBus systems support both 16-bit PC Card cards and CardBus cards. In this environment, interrupt sharing becomes an issue because CardBus controllers can use PCI interrupts, which are level-sensitive and sharable. To help alleviate interrupt limitations in CardBus systems, Windows can take advantage of PCI interrupt-sharing capabilities.

In cases where no ISA IRQs are available to a 16-bit PC Card card in a CardBus controller, the operating system will assign a PCI interrupt to the card. All 16-bit PC Card card drivers must 'hook' the interrupt, whether it is sharable or not, before its hardware generates any interrupts.

B2.1.4.4 No user intervention; no system restart occurs when installing devices, except when required by the operating system

See PCCard-11 through PCCard-20 and 21 in 'Design Guidelines for PC Card and CardBus, Version 1.1'PCCard-20, 21

B2.1.4.5 ZV-compatible 16-bit PC Cards comply with ZV standard definitions, and driver uses DirectDraw VPE

ZV-compatible PC Card drivers must use software interfaces based on 32-bit Microsoft DirectDraw® Video Port Extensions (VPE) in order to configure the graphics controller to receive video input using the ZV port. This includes programming the graphics controller to configure the format of the video data, its location on screen, and so on. VPE is part of Microsoft DirectX® APIs.

ZV card device drivers must handle dynamic graphics state changes, such as resolution changes, color depth changes, and switching to and from full-screen MS-DOS®–based applications.

B2.1.4.6 CardBus controller designed to support wake-from-D3cold supports PME# assertion from D3cold, and socket supplies Vaux power to cards in D3cold state

CardBus cards (which are by definition PCI devices) must comply with PCI Bus Power Management Interface Specification, Revision 1.1 or later, in order for power management to be implemented properly under Windows, which uses PME# as the wake-up signal. This is the only industry specification that ensures compatibility with the power management capabilities of Windows.

The CardBus card must use the CSTSCHG pin to signal wake-up events. This is because there is no PME# pin on the CardBus interface, and the CardBus card must use PME_EN in the card’s Configuration Space to enable wake-up events. Specifically, setting the PME_EN bit in the card’s Configuration Space must provide the same behavior as setting both the GWAK and WKUP bits in the card’s Function Event Mask register.

If wake-from-D3cold is implemented in a platform, the following are required:

• 
  Associated CardBus controller must support PME# assertion from D3cold.
  
• 
  Associated socket must supply sufficient Vaux power to support the card in its D3cold state.
  

This requirement must be independently met by each enabled D3cold-wake-capable CardBus socket in the system, as defined in the host system chapter of PC Card Standard, version 7.

B2.5.1.7 Correct PCI implementations

If PCI is present in the system, the PCI bus and PCI expansion connectors must meet the requirements defined in the PCI 2.2 specification, plus any additional PCI requirements listed here.

B2.5.3.2.1 Device IDs include PCI Subsystem IDs.

The Subsystem ID (SID) and SVID fields must comply with the SID requirement in PCI 2.2 and the implementation details provided in “PCI Device Subsystem IDs and Windows” at http://www.microsoft.com/hwdev/bus/pci/pciidspec.asp.

AMR devices and MR devices on the system board are not exempt from the requirement for SID and SVID.

See also A1.1.3

B2.5.3.2.2 System does not contain ghost devices.

Bus designs must fully implement all bus requirements on every expansion card connector. A computer must not include any ghost devices, which are devices that do not correctly decode the Type 1/Type 0 indicator. Such a device will appear on multiple PCI buses. A PCI card should be visible through hardware configuration access at only one bus/device/function coordinate.

B2.5.3.2.3 System uses standard method to close base address register (BAR) windows on nonsubtractive decode PCI bridges.

Nonsubtractive decode PCI bridges must implement the standard method to close BAR windows as defined in the PCI to PCI Bridge Architecture Specification Rev. 1.1. Setting the BAR to its maximum value and the limit register to zeros effectively closes the I/O or memory window references in that bridge BAR.

B2.5.3.2.6 DELETED

B2.5.3.2.7 Configuration Space is correctly populated.

PCI 2.2 describes the configuration space used by the system to identify and configure each device attached to the bus. The configuration space is made up of a header region and a device-dependent region. Each configuration space must have a 64-byte header at offset 0. All the device registers that the device circuit uses for initialization, configuration, and catastrophic error handling must fit within the space between byte 64 and byte 255.

All other registers that the device uses during normal operation must be located in normal I/O or memory space. Unimplemented registers or reads to reserved registers must complete normally and return zero. Writes to reserved registers must complete normally, and the data must be discarded.

All registers required by the device at interrupt time must be in I/O or memory space.

B2.5.3.2.8 Interrupt routing is supported using ACPI.

The system must provide interrupt routing information using a _PRT object, as defined in Section 6.2.3 of ACPI 1.0b (for x86-based systems) and Section 6.2.8 of ACPI 2.0 (for Itanium-based systems). It is important to note that the _PRT object is the only method available for interrupt routing on Itanium-based systems.

B2.5.3.2.11 DELETED

B2.5.3.2.12 PCI devices decode only resources found in the Devices BAR.

PCI devices must not decode cycles that are not their own to avoid contention on the PCI bus. Notice that this requirement does not in any way prohibit the standard interfaces provided for by the PCI cache support option discussed in PCI 2.2, which allows the use of a snooping cache coherency mechanism. Auxiliary hardware that is used to provide non-local console support is permitted within the scope of this requirement.

B2.5.4 PCI Controllers/Devices - Windows Experience

B2.5.4.1 Power management supported as defined in PCI Bus Power Management Interface Specification, Rev. 1.1 (PCI-PM)

PCI Bus Power Management Interface Specification, Revision 1.1, is the only industry specification that ensures compatibility with the power management capabilities of Windows, which uses PME# as the wakeup signal.

The primary PCI bus controller, PCI-to-PCI bridges, devices that implement PME# must comply with the PCI Bus Power Management Interface Specification, Revision 1.1. PCI add-on devices that do not implement PME# must comply with PCI-PM 1.0.

See also A4.1.1

B2.5.4.1.1 System provides 3.3 V to all PCI connectors.

System supports 3.3 Vaux if the system supports S3 or S4 states for integrated devices that support waking the system and all PCI slots including MiniPCI.

System support for delivery of 3.3Vaux to the PCI bus must be capable of powering a single PCI slot with 375 mA at 3.3V and it must also be capable of powering each of the other PCI slots on the segment with 20 mA at 3.3V whenever the PCI bus is in the B3 state.

System support for delivery of 3.3Vaux to a PCI bus segment must be capable of powering a single PCI slot on that bus segment with 375 mA at 3.3V and it must also be capable of powering each of the other PCI slots on the segment with 20 mA at 3.3V whenever the PCI bus is in the B3 state.

In the case of systems with multiple PCI bus segments, delivering 3.3Vaux to one PCI bus segment does not mean that all PCI bus segments will be required to implement delivery of 3.3Vaux. However, if a system with multiple PCI bus segments provides 3.3Vaux to one or more segments and not to all segments in the system, these capabilities must be clearly marked and documented so that the end user can determine which slots support this capability. Examples of methods for indicating which slots support 3.3Vaux include icons silk-screened on system board sets, slot color-coding, and chassis icons.

Systems must be capable of delivering 375 mA at 3.3V to all PCI slots on a power-managed bus segment whenever the PCI bus is in any “bus powered” state: B0, B1, or B2.

B2.5.4.1.2 PCI add-on cards that use 3.3 Vaux operate correctly, using a method such as the one described in Section 7.4.4 of PCI-PM 1.1.

PCI add-on cards that use 3.3Vaux must operate correctly. This applies when the system supports 3.3Vaux to the PCI connectors.

B2.5.4.1.3 Bus power states are correctly implemented.

The PCI bus and all add-on capable devices on the PCI bus must comply with PCI Bus Power Management Interface Specification, Revision 1.1 or later. This includes correct implementation of the PCI configuration space registers used by power management operations, and the appropriate device state (Dx) definitions for the PCI bus and all add-on-capable devices on the PCI bus. ACPI is not an acceptable alternative.

B2.5.R PCI Controllers/Devices - Future Requirements

Announcement of additional future requirements will be published at http://www.microsoft.com/winlogo/hardware/.

B2.5.R.1 PCI Subsystem IDs and PCI-to-PCI bridge devices

See 'PCI Subsystem IDs and PCI-to-PCI Bridge Devices' at http://www.microsoft.com/hwdev/bus/pci/pcibridge.asp.

B2.5.R.2 Functions in a multifunction PCI device do not share writable PCI Configuration Space bit.

Windows treats each function of a multifunction PCI device as an independent device. As such, there can be no sharing between functions of writable PCI configuration space bits (such as the Command register).

B2.5.R.3 Hot-Plug PCI supported via compatible driver solutions or ACPI

Windows Longhorn supports dynamic enumeration, installation, and removal of PCI devices if the implementation strictly complies with the PCI Standard Hot-Plug Controller and Subsystem Specification (SHPC), Revision 1.0, and the Windows Logo Program requirements for the SHPC driver.

SHPCs that have been designed to meet these requirements do not need any ACPI implementations or vendor-supplied filter drivers. SHPCs will be required for systems running Windows 'Longhorn' that provide Hot-Plug PCI support. Other hot-plug implementations will work under Windows only if there is a supported hardware insert/remove notification mechanism, such as a bus standard. An example of an implementation based on an appropriate standards-based notification mechanism is a CardBus bus controller.

For more information about Windows and PCI Hot Plug, see 'Hot-Plug PCI and Windows' at http://www.microsoft.com/hwdev/bus/pci/hotplugpci.asp.

B2.5.R.4 PCI 2.3 Interrupt Disable

PCI 2.3 Interrupt Disable is required for Longhorn logo for all devices that are first submitted for logo after January 1st, 2004. All devices being submitted for logo testing must include this capability by January 1st, 2006. See section 6.2 of the PCI Local Bus Specification Revision 2.3.

B2.6 USB Controllers and Devices

All general requirements in B1.0 are included by reference.
