B18.104.22.168 Device configuration and detection requirements
B22.214.171.124.2 Primary graphics adapter works normally with default VGA mode driver.
Primary graphics adapter works normally with default VGA mode driver
The default VGA driver is required for installing the operating system. The primary adapter must support 4-bit planar VGA mode as described in the Windows DDK.
B126.96.36.199.3Driver does not bypass any Microsoft-provided system components.
This requirement applies for all files normally installed in the System32 directory. These files include, but are not limited to, Win32k.sys, Ntoskrnl.exe, Gdi32.dll, User32.dll, and Mcdsrv32.dll.
B188.8.131.52.4 Adapter supports DDC monitor detection.
And option ROM supports VESA Enhanced Display Data Channel Standard (EDDC), Version 1.0, Level 2B protocols (DDC2B).
The adapter must support the DDC2B host requirements identified in the VESA Enhanced Extended Display Data Channel Standard (E-DDC), Version 1, which defines the communication channel between the display and host system. The software can use this information to properly manage output to the various displays and to prevent the disabling of television output if no monitor is attached. Devices capable of multihead display must support this feature for all attached monitors.
Mobile PC Note: Requirements are defined in A184.108.40.206.
B220.127.116.11.5 Frame buffer can be accessed directly by applications.
Frame buffer can be accessed asynchronously by the CPU and graphics accelerator. It must be possible for applications to perform direct frame buffer accesses at any time, even while asynchronous accelerator operations are being executed.
B18.104.22.168.7 BIOS supports large frame buffers for graphics adapters.
The system BIOS must support large frame-buffer graphics adapters that have up to 256 MB of frame buffers.
B22.214.171.124.8 Graphics adapter complies with VESA BIOS Extensions/Core 2.0 extensions for power management.
The VESA BIOS Extension Standard/Core Functions 2.0 (VBE/Core 2.0) specification defines extensions to VGA ROM BIOS services for power management.
Note: The required support defined in Version 3.0 of the DDC and Extended Display Identification Data (EDID) standards is also defined in the earlier version and revisions of these standards. As such, the Version 3.0 standards provide the correct references for Windows XP.
Mobile Note: See A126.96.36.199.5
