There are a few considerations to keep in mind when writing drivers that may be ported to EBC (EFI byte code). This chapter describes these considerations in detail and, where applicable, provides solutions to address them. If UEFI drivers are implemented with these considerations in mind, the C code may not require any changes. In this case, a native driver may be ported to EBC simply by recompiling the driver sources using the Intel(R) C Compiler for EFI Byte Code. The tasks required to convert a UEFI Driver to an EBC include the following:
