Wake On LAN
Wake on LAN is not supported for QLogic 8100 Series Adapters.
PXE Boot
PXE boot code is a part of the QLogic 8100 Series Adapter multi-boot image that
enables a networked server to boot with the images provided by remote servers.
The PXE protocol, illustrated in Figure 6-38, operates as follows:
1. The client initiates the protocol by broadcasting a DHCPDISCOVER
containing an extension that identifies the request as one coming from a
client that implements the PXE protocol.
2. Assuming that a DHCP server or a proxy DHCP server is available that is
capable of implementing this extended protocol, after several intermediate
steps, the server sends a list of appropriate boot servers to the client.
3. The client then discovers a boot server of the selected type and receives the
name of an executable file on the chosen boot server.
4. The client uses TFTP to download the executable from the boot server.
5. Finally, the client executes the downloaded image. At this point, the client's
state must meet certain requirements to provide a predictable environment
for the image. These requirements include the availability of certain areas of
the client's main memory and the availability of basic network I/O services.
