- Cirrus Logic 5430 Controller Driver.
- This driver is a sample implementation of the UGA Draw and Graphics Output
- Protocols 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 and Graphics output 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.
