13 | 0x2000 | Boots the default Flash memory software if the network boot |
|
| fails |
|
|
|
14 | 0x4000 | Excludes network numbers from IP broadcasts |

1.The factory default value for the software configuration register is 0x0102. This value is a combination of binary bit 8 = 0x0100 and binary bits 00 through 03 = 0x0002.
2.OEM = original equipment manufacturer.
Note Valid software configuration register values may be combinations of settings, rather than the individual settings listed in Table 8. For example, the factory default value 0x0102 for the software configuration register is a composite of several settings.
