Description
This function enables the use of the PXE Base Code Protocol functions. If the Started field of
the EFI_PXE_BASE_CODE_MODE
structure is already TRUE, then EFI_ALREADY_STARTED
will be returned. If UseIpv6 is TRUE, then IPv6 formatted addresses will be used in this session.
If UseIpv6 is FALSE, then IPv4 formatted addresses will be used in this session. If UseIpv6 is
TRUE, and the Ipv6Supported field of the EFI_PXE_BASE_CODE_MODE structure is
FALSE, then EFI_UNSUPPORTED will be returned. If there is not enough memory or other
resources to start the PXE Base Code Protocol, then EFI_OUT_OF_RESOURCES will be returned.
Otherwise, the PXE Base Code Protocol will be started, and all of the fields of the
EFI_PXE_BASE_CODE_MODE structure will be initialized as follows:
Started Set to TRUE.
Ipv6Supported Unchanged.
Ipv6Available Unchanged.
UsingIpv6 Set to UseIpv6.
BisSupported Unchanged.
