Configuring SAN Boot (Legacy Mode)

You can configure SAN Boot for the MZ912 in the Emulex FCoE or FC x86 BIOS. To configure SAN Boot, perform the following steps:

1. Start the MZ912, and press Ctrl+E to enter the Emulex FCoE or FC x86 BIOS when the message shown in Figure 4-1 or Figure 4-2 is displayed. The message shown in Figure 4-1 is displayed if the MZ912 operates in NIC+FCoE mode, and the message shown in Figure 4-2 is displayed if the MZ912 operates in NIC+FC mode.

2. Select a port.

   Figure 4-3 shows the screen for selecting a port for SAN Boot (FCoE mode).
