Chapter 2 - Hardware Requirements for Windows LogoThese guidelines define the Windows Logo Program requirements for consistent, stable operating system functionality and help ensure a satisfactory customer experience. Compliance dates for specific Windows Logo Program requirements are defined on the web at http://www.microsoft.com/winlogo/hardware/. Summary of Windows Logo RequirementsThe Windows Logo Program requirements consist of the following for each operating system for which the vendor is seeking the “Designed for Windows” logo:
Implementation guidelines for drivers are defined in the Microsoft Windows DDK. Note that the PC and Server Design Guides do not define the Windows Logo Program requirements; rather, these publications provides feature guidelines for system and component design. Windows Logo Program Requirements WL-1. Deleted WL-2. System memory provides a satisfactory user experience WL-3. Deleted WL-4. All components and devices meet Windows compatibility and quality design guidelines WL-5. Deleted WL-6. System and components support operating system configuration and control of devices WL-7. System and peripherals implement ease-of-use guidelines for a good end-user experience WL-8. Deleted WL-1. DELETEDWL-2. System memory provides a satisfactory user experienceBecause objective benchmarks are not available, the intent of this requirement is to define a memory size that represents the baseline of acceptable Windows performance. The following summarizes the Windows Logo Program performance requirements. 2001-2002 Minimum Equivalent Performance Requirements
Note 1: For systems with shared memory architecture and 128-MB system RAM, collectively, the drivers supporting integrated chipset functionality must not lock more than 32 MB. These maximum-page-locked-memory limits apply during all phases of system startup and normal operation. Page-locked graphics memory includes all frame buffers and buffers for hardware acceleration, texture and lighting, Z, and AGP. Page-locked audio memory includes all memory locked by the audio driver including all wave tables, and so on. Dynamic memory allocation under the Windows environment is allowed, subject to the paged-locked memory limit. The driver cannot advertise or switch into a graphics mode that cannot be supported within the maximum locked memory limit. Note 2: PC client systems must have at least the minimum system memory installed. Note 3: Server system memory configurations specify the minimum allowed system memory to run the HCT. It is recognized that OEMs supply systems with specific feature requirements to corporations, which can include providing servers that do not include any preinstalled memory or that meet specific customer requirements for installed memory. WL-3. DELETEDWL-4. All components and devices meet Windows compatibility and quality design guidelinesThe compatibility and quality guidelines include requirements for devices, drivers, and software included with the system or retail component. For specific feature and functionality requirements for each type of system, see Appendix A, "System Requirements Checklist." Device RequirementsAny buses, devices, or other components offered with a Logo’d system or offered as a retail product carrying the "Designed for Windows" logo must pass related feature tests and operating system compatibility tests published by WHQL. For the complete checklist of device and bus requirements, see Appendix B, "Device Requirements Checklist." Driver and Software RequirementsThese requirements ensure a good user experience when installing and using any component:
Loading of a driver must not reduce or eliminate the functionality of other devices installed on the system.
Poorly written kernel-mode drivers have the potential to cause the system to become unstable or stop working. Therefore, it is critical that all kernel-mode drivers be thoroughly tested to minimize this risk. For information about using Driver Verifier and diagnosing driver problems, see http://www.microsoft.com/hwdev/driver/verifier.asp.
Other WHQL test programs that require digital signatures include the following:
For details about what is tested for HALs, see Chapter 26, “HAL Test Specification,” in WHQL Test Specification.
For details about what is tested for anti-virus software, see Chapter 21, “Anti-virus File System Filter Test Specification,” in WHQL Test Specification. Note: Additional requirements related to driver and software quality may be added as tests become available. "New Technology" RequirementsFor new or other technologies where specific compatibility tests have not been defined under the Windows Logo Program (as provided in the HCTs from WHQL), or where design guidelines have not been provided in a Design Guide, the following requirements apply:
