Mobile PC Note: Requirements are defined in A3.4.4.7.
B4.1.4.6.5 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.
B4.1.4.6.6 DELETED B4.1.4.6.7 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.
B4.1.4.6.8 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.
