Type The type of bootstrap to perform. See “Related Definitions”.
Layer Pointer to the boot server layer number to discover, which must be
PXE_BOOT_LAYER_INITIAL when a new server type is being
discovered. This is the only layer type that will perform multicast and
broadcast discovery. All other layer types will only perform unicast
discovery. If the boot server changes Layer, then the new Layer will
be returned.
UseBis TRUE if Boot Integrity Services are to be used. False otherwise.
Info Pointer to a data structure that contains additional information on the
type of discovery operation that is to be performed. If this field is NULL,
then the contents of the cached DhcpAck and ProxyOffer packets
will be used.
