Installing the ESXi 4.1 OS
VMware ESXi 4.1 is not UEFI aware. Therefore, you must use the Legacy Only option as the
first boot option. To decrease the boot time, the optimal minimum configuration is Legacy
Only, CD/DVD Rom, and Hard Disk 0.
Use the following steps to install ESXi 4.1 Server onto x3850 X5 with MAX5 attached:
1. Power on the system and press F1 when the UEFI splash panel is shown.
2. Select Boot Manager  Add Boot Option.
3. Select CD/DVD Rom, Legacy Only, and Hard Disk 0. If either option is not listed, the
option is already included in the boot list.
4. Press Esc when finished to go back one panel.
5. Select Change Boot Order and change the boot order to look like Figure 6-53 on
page 276.
