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