- Cirrus Logic 5430 Controller Driver.
- This driver is a sample implementation of the UGA Draw Protocol for the
- Cirrus Logic 5430 family of PCI video controllers. This driver is only
- usable in the EFI pre-boot environment. This sample is intended to show
- how the UGA Draw Protocol is able to function. The UGA I/O Protocol is not
- implemented in this sample. A fully compliant EFI UGA driver requires both
- the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
- documentation on UGA for details on how to write a UGA driver that is able
- to function both in the EFI pre-boot environment and from the OS runtime.
