Các bác có biết vì sao Dell 1300 dùng chip VGA 915GM mà trên trang web của Dell thông báo là không có Aero không ạ Các loại máy khác cũng dùng chip 915 hình như là hiển thị được thì phải ạ . Vì sao vậy nhỉ ? Hay tại số em đen .
Muốn xài được Aero thì phải có driver dạng WDDM cho card màn hình của bạn mà cái 915GM Intel nó ko chịu làm driver WDDM nên 915GM ko xài được Aero đâu.

Q3: Is Intel providing support for WDDM drivers for Intel Graphics Media Accelerator 900 (Intel GMA 900) on Intel® 915 Express chipset-based platforms?
A: Intel will provide support for WDDM drivers beginning with the Intel® 945 Express chipset family and beyond.
Windows Vista is supported on the Intel® 845G, 865G, 915G Express desktop chipsets and 852/855GM mobile chipsets running XP drivers for Intel graphics. Windows Vista will install on these platforms, but advanced features such as Windows Aero will not be enabled as Vista drivers using WDDM are required for Windows Aero.
Em cám ơn bác nhiều. Em đọc thấy đoạn sau của Intel nói về nó nhưng do em dốt Eng quá nên em nhờ các bác cao thủ Eng dịch hộ ạ. Thanks các bác nhiều.
Q5: Why doesn’t the Intel 915 Express chipset family support Windows Vista Aero?
A: The overall graphics architecture and design of the 915 Express chipset family (with Intel® Graphics Media Accelerator 900 graphics engine) was finalized prior to Microsoft releasing details and specifications around the Windows Display Driver Model (WDDM) driver and running the Aero interface. Given this, there are hardware limitations in the 915 Express chipset architecture that would limit graphics performance and memory capabilities when attempting to run WDDM on Vista.
The hardware limitations of 915/GMA900 graphics center around not having a large enough memory table to support Vista Aero, a key feature that is part of WDDM driver support. This, along with hardware restrictions on surface placement and graphics memory alignment, results in graphics memory usage that is not optimized for Aero performance. Additionally, the lack of native hardware support in the 915 Express chipset family for Vista’s dynamic memory management would result in slower graphics performance and a sub-optimal user experience with Windows Vista Aero.
With these identified limitations, the 915/GMA900-based graphics system would not have met the performance requirements for Aero desktop composition support under Vista. This ultimately led to the decision to begin WDDM support with the Intel® 945 Express chipset products, as Intel addressed these hardware limitations with the desktop and mobile Intel® 945 Express chipset families.
To provide the best performance and user experience with Windows Vista on Intel® 915/GMA900 platforms, Intel will support Windows Vista on 915/GMA900 with the drivers based on the XP driver model.
Q6: Does the Windows XP Driver Model (XPDM) support statement on Vista include the entire Intel 915 Express chipset family? Does it include the Intel 915GMS or 910GM/GML Express Chipsets?
A: The entire Intel 915 Express chipset family is included in the XPDM support statement for Windows Vista, including Intel 915GMS and 910GM/GML Express chipsets. Only XPDM drivers will be available for the Intel 915 and 910 Express chipset families using Intel graphics running Windows Vista.
