4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  Cirrus Logic 5430 Controller Driver.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  This driver is a sample implementation of the UGA Draw and Graphics Output
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  Protocols for the Cirrus Logic 5430 family of PCI video controllers.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  This driver is only usable in the EFI pre-boot environment.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  This sample is intended to show how the UGA Draw and Graphics output Protocol
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  is able to function.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  The UGA I/O Protocol is not implemented in this sample.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  A fully compliant EFI UGA driver requires both
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  the UGA Draw and the UGA I/O Protocol.  Please refer to Microsoft's
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  documentation on UGA for details on how to write a UGA driver that is able
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync  to function both in the EFI pre-boot environment and from the OS runtime.
