+If you want to make your override persistent over reboots use the `persistent` option:
+```
+$ ipmitool -C 17 -H "$BMC_IP" -I lanplus -U "$BMC_USER" -P "$BMC_PASSWD" chassis
+bootdev <device> options=persistent
+```
+
+##
+
+If the main host machine is based on the x86 CPU you need also pay attention to
+the legacy/EFI mode selector. By default IPMI overrides boot source with the legacy
+mode enabled. To set EFI mode use `efiboot` option:
+```
+$ ipmitool -C 17 -H "$BMC_IP" -I lanplus -U "$BMC_USER" -P "$BMC_PASSWD" chassis
+bootdev <device> options=efiboot
+```
+
+You can combine options with a help of `,`:
+```
+$ ipmitool -C 17 -H "$BMC_IP" -I lanplus -U "$BMC_USER" -P "$BMC_PASSWD" chassis
+bootdev <device> options=persistent,efiboot
+```
+
+##
+
+To read current boot source override setting:
+```
+$ ipmitool -C 17 -H "$BMC_IP" -I lanplus -U "$BMC_USER" -P "$BMC_PASSWD" chassis
+bootparam get 5
+```
