TFTP API
The TFTP (Trivial File Transfer Protocol) API enables opening and closing of TFP connections
and reading packets from and writing packets to a TFTP connection. The PXE client downloads
the PXE boot loader from an TFTP server.

UDP API
The User Datagram Protocol (UDP) API enables opening and closing of UDP connections and
reading packets from and writing packets to a UDP connection.

UNDI API
The Universal Network Device Interface (UNDI) API enables basic control of I/O through the
adapter. This allows the use of universal protocol drivers that can be used on any network
interface that implements this API. UNDI is used by the PXE protocol to enable basic control of
I/O and performs other administrative chores like setting up the MAC address and retrieving
statistics through the adapter.

The Brocade PXE BIOS Configuration Utility (embedded with the boot code), BCU commands, and
the HCM allow you to perform the following tasks:

Enable or disable BIOS.
When enabled, the system BIOS can execute the Brocade BIOS code for a specific adapter port
for PXE boot over the network.

Set a VLAN ID to be used during network boot for the specific port.

NOTE

Enabling VLAN during network boot requires support from the operating system and has not
been fully validated due to operating system limitations.

Host system requirements for network boot

Consider these requirements for your host system when configuring network boot:

You may need to disconnect internal IDE hard drives to disable them in the system BIOS and
allow the adapter boot BIOS to boot from the remote system. Some systems may allow these
drives to be enabled in the system BIOS if they correctly support the bootstrap protocol.

Typically, the boot order must be CD-ROM, diskette, then remote boot system. After the
operating system installs, you can change this order if desired.

Due to the variety of configurations and variables in a LAN installations, your specific environment
must determine any additional requirements to guide installation and configuration for best
results.

Driver support for network boot

Refer to

“Boot installation packages”

on page 49.

Table 10

on page 51 for applicable DUDs for

supported operating systems. Notes following the table identify DUDs that support network boot.
Note the following:

Windows 2008
For network boot, the network driver is injected as part of the PXE Server prior to Windows
installation. The driver is passed over during PXE installation on the server.
