#1: The size of the video BIOS might change in future versions.
#2: The extended BIOS space is a narrow space between D0000 and DFFFF, and might already be in use by other
devices. In addition, the size of the BIOS of the standard built-in adapters might change in future versions. If
possible, we recommend not using the BIOS space when designing a new device. If you do, a conflict might occur
between devices, resulting in device malfunctions.
