ARS Technica is running a story on the requirements that Microsoft has released to OEMs in order for hardware to be “Vista Premium” certified.
In no particular order, these are the notable additional requirements for Premium certification:
Effective now:
* HD Audio support that passes a “high-fidelity audio experience” test (exception: Business class systems have until June 1, 2007).
* Support for Direct3d 9 and DXGI feature sets (Direct3d 10 mandated by June 1, 2008).
* At least one digital output (e.g., DVI-D) for all add-in video adapters (not integrated video: that doesn’t change until June 1, 2008).
* 100Mb Ethernet and/or and WiFi (802.11g must be supported; 802.11a can be supported only in addition to 802.11g).
* USB 2.0 ports throughout
* System resumes from ACPI S3 state (“suspend-to-ram”) in <2 seconds (does not include user mode initialization, i.e., total "wake" time will be longer than 2 seconds) June 1, 2007, or later: * A Green Driver Quality Rating for all drivers. * If Serial ATA is used, Serial ATA 2.5 must be supported. * "Protected Video Path" (PVP) support, including HDCP. * Support for booting from USB drives, including flash drives * Hiccup-free HD playback, including hardware-based H.264/MPEG-4 decoding. * At least one digital output (e.g., DVI-D) for all integrated video adapters (June 1, 2008).
