401A | Terminal Type | The BIOS console redirection, if enabled, operates in |
|
| VT100 emulation model. See tokens BFh, C0h, and |
|
| D7h. |
401B | Terminal Type | The BIOS console redirection, if enabled, operates in |
|
| ANSI emulation model. See also tokens BFh, C0h, |
|

401C | Redirection After | The BIOS console redirection, if enabled, continues to |
| BIOS POST | operate after the OS boot |
401D | Redirection After | The BIOS console redirection, if enabled, operates |

|
| and 401Bh. |
4022 | 1st Boot Device | Whenever the BIOS boots the system, the first PXE- |
|
| capable device is inserted as the first device in the |
|
| boot sequence. Enabling this feature causes the BIOS |
operation to occur on the next and all subsequent boots and causes a change in the system's defined boot sequence. The BIOS chooses the first PXE- capable device as the system's onboard network controller, if present and enabled, or the first bootable network device found in the system's standard PCI search order.
