15.3 PXE Base Code Protocol
This section defines the Preboot Execution Environment (PXE) Base Code protocol, which is used
to access PXE-compatible devices for network access and network booting. More information
about PXE can be found in the Preboot Execution Environment (PXE) Specification at:

.
EFI_PXE_BASE_CODE Protocol
Summary
The EFI_PXE_BASE_CODE protocol is used to control PXE-compatible devices. The features of
these devices are defined in the Preboot Execution Environment (PXE) Specification. An
EFI_PXE_BASE_CODE protocol will be layered on top of an EFI_SIMPLE_NETWORK
protocol
in order to perform packet level transactions. The EFI_PXE_BASE_CODE handle also supports
the LOAD_FILE
protocol. This provides a clean way to obtain control from the boot manager if
the boot path is from the remote device.
