2 | Cirrus Logic 5430 Controller Driver.\r | |
3 | This driver is a sample implementation of the UGA Draw and Graphics Output\r | |
4 | Protocols for the Cirrus Logic 5430 family of PCI video controllers.\r | |
5 | This driver is only usable in the EFI pre-boot environment.\r | |
6 | This sample is intended to show how the UGA Draw and Graphics output Protocol\r | |
94b73c24 | 7 | is able to function.\r |
87f8ccbe | 8 | The UGA I/O Protocol is not implemented in this sample.\r |
9 | A fully compliant EFI UGA driver requires both\r | |
10 | the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's\r | |
11 | documentation on UGA for details on how to write a UGA driver that is able\r | |
12 | to function both in the EFI pre-boot environment and from the OS runtime.\r | |
