Ensure that the Windows operating system is supported on each target manageable server. For a list of manageable servers that support the Windows operating system, see Table 2–6.
Set the BIOS Settings on the target host in the following order:
Identify the target host's primary NIC MAC address for a PXE network boot and the Globally Unique Identifier (GUID) value.
You can obtain the GUID from the target host's BIOS settings or from any of the following other sources:
A label on the side of the computer case.
A label within the computer case.
The basic input/output system (BIOS) of the client computer.
Network traffic from the client computer. You can use a network utility to sniff the network traffic and locate the DHCPDiscover packet. That field will contain the 128-bit, 16-byte GUID or a 128 bit Universally Unique IDentifier (UUID).
The GUID must be in the form {dddddddd-dddd-dddd-dddd-dddddddddddd}, where d is a hexadecimal text digit. For example, {921FB974-ED42-11BE-BACD-00AA0057B223}. Valid entries for the client GUID are restricted to the numbers 0 through 9, lowercase alphabetical characters, uppercase alphabetical characters, and a dash.
Spaces, underscores, and other special symbols are not permitted in a GUID nor in a UUID.
