5. If the initiator logs into the fabric, but is unable to log into the target, a CTRL+R will pause the boot process and allow you to configure fabric zoning.
6. Once zoning is complete, the initiator will automatically log into all visible targets. If the initiator is unable to discover the designated LUN on the designated target as provisioned in

step 1, CTRL+R will pause the boot process and allow you to configure selective LUN presentation.

7. The boot initiator will periodically poll the LUN for readiness, and once the user has provisioned access to the LUN, the boot process will automatically proceed.

NOTE: This does not preclude the need to put the boot initiator into one-time disabled mode as described in

One-Time Disabled

One-Time Disabled

Broadcom's FCoE ROM is implemented as Boot Entry Vector (BEV). In this implementation, the Option ROM only connects to the target once it has been selected by BIOS as the chosen
boot device. This is different from other implementations that will connect to the boot device even if another device has been selected by the system BIOS. For OS installation over the
FCoE path, it is necessary to instruct the Option ROM to bypass FCoE and skip to CD/DVD installation media. As instructed earlier, the boot order must be configured with Broadcom boot
first and installation media second. Furthermore, during OS installation, it is required to bypass the FCoE boot and pass through to the installation media for boot. It is required to do this
by one-time disabling the FCoE boot ROM from booting, and not by simply allowing the FCoE ROM to attempt to boot and allowing the BIOS to fail through and boot the installation media.
Finally, it is required that the FCoE ROM successfully discover and test the readiness of the desired boot LUN in order for installation to proceed successfully. Failure to allow the boot ROM
to discover the LUN and do a coordinated bypass will result in a failure to properly install the O/S to the LUN. In order to affect this coordinated bypass, there are two choices:

Once the FCoE boot ROM discovers a ready target LUN, it will prompt you to press CTRL+D within 4 seconds to Stop booting from the target. Press CTRL+D, and proceed to
boot from the installation media.
From CCM, set the Option ROM setting under MBA settings to One Time Disabled. With this setting, the FCoE ROM will load once and automatically bypass once the ready LUN is
discovered. On the subsequent reboot after installation, the option ROM will automatically revert to Enabled.

Wait through all option ROM banners. Once FCoE Boot is invoked, it will connect to the target, and provide a 4 second window to press CTRL+D to invoke the bypass. Press CTRL+D to
proceed to installation.

Windows Server 2008 R2 and Windows Server 2008 SP2 FCoE Boot Installation

Ensure that no USB flash drive is attached before starting the OS installer. The EVBD and OFC/BXFOE drivers need to be loaded during installation. Go through the normal procedures for
OS installation. When no disk devices are found, Windows will prompt you to load additional drivers. At this point, connect a USB flash drive containing the full contents of the provided
EVBD and OFC boot driver folders. After all appropriate drivers are loaded, the setup show the target disk(s). Disconnect the USB flash drive before selecting the disk for installation.

1. Load the EVBD driver first.
