Description
Reserved (Read Only). Reads back as 0.
Signature Value (Read Only). A 32-bit signature value is stored in this field when in 32-
bit CRC mode and can be read at any time. The 32-bit CRC mode select bit is located in
VP Diagnostic MSR (MSR 48000010h[31]). The signature is produced from the RGB
data before it is sent to the CRT DACs. This field is used for test purposes only.
See VP Memory Offset 088h for more information.

Alpha Window 3 Priority. Indicates the priority of alpha window 3. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha
windows.
This field is reset by hardware to 00.
Alpha Window 2 Priority. Indicates the priority of alpha window 2. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha
windows.
This field is reset by hardware to 00.
Alpha Window 1 Priority. Indicates the priority of alpha window 1. A higher number indi-
cates a higher priority. Priority is used to determine display order for overlapping alpha
windows.
