- 0 Power-up display configuration.
- HWBufferSize
- Size to save video state
- Size of the buffer required by the Base Video Handler (BVH) to save the full hardware state, excluding the physical display buffer.
- FullSaveSize
- Full save size.
- Maximum size buffer required by the BVH to save the full physical display buffer.
- PartSaveSize
- Partial save size
- Maximum size buffer required by the BVH to save the portion of the physical display buffer that is overlaid by a pop-up.
- EMAdaptersOFF
