17 BP1043 | Configuring Windows Server 2008 R2 for iSCSI SAN Boot with EqualLogic Storage
5 Preparing Intel Network Adapters for iSCSI boot
Note: Intel network adapters are not shipped with iSCSI enabled in the Boot ROM. You must enable iSCSI
so that Intel network adapters are detected as a boot device and are listed in the “Boot Sequence”.
During the system boot if you do not see the Ctrl+D option to configure the Intel NIC then follow the
following the steps in this section to enable iSCSI on the Intel network adapter.
You must perform the following steps to enable iSCSI remote boot in the Boot ROM on the Intel network
adapter.
1. Create a DOS bootable USB flash drive.
Note: The open source utility UNetbootin can be used to create a DOS bootable USB flash drive using
FreeDOS. The utility can be downloaded from http://unetbootin.sourceforge.net/.
2. Download the Intel Boot Agent from the Intel support website. The file is named: “Preboot.exe”
Note: The support site for Intel is www.intel.com/support.
3. Extract the “Preboot.exe” zip file to the bootable USB key created in step 1.
4. With the Intel NIC installed, boot the server using the DOS bootable USB key.
5. Once the system boots from the DOS bootable USB key, change to the directory containing the
Boot Agent (\Preboot\Apps\Bootutil\Dos). To enable the capability to run flash firmware on the
selected adapter, run the following command:
bootutil.exe –all -fe
6. If this command returns an error, then program the flash using this command:
“bootutil.exe –up=combo –all –File=<path>/bootimg.flb”
See Figure 4 for more detail.
Then repeat step 5 to enable flash on the network adapter. (bootimg.flb is not in the same location
as bootutil.exe, bootimg.flb is available in Preboot\apps\bootutil.)
