| 32 | If this is set, the verstage returns back to the bootblock instead of |
| 33 | exits to the romstage so that the verstage space can be reused by the |
| 34 | romstage. Useful if a ram space is too small to fit both the verstage |
| 35 | and the romstage. |

| 50 | When this option is enabled, the Chrome OS device leaves the |
| 51 | developer mode as soon as recovery request is detected. This is |
| 52 | handy on embedded devices with limited input capabilities. |
