| Variable | Description |
|---|---|
| auto_action | Sets the console action following an error, halt, or power-up. The action can be halt, boot, or restart. Halt is the default. |
| bootdef_dev | Sets the default device or device list from which the system will attempt to boot. If the system shipped with its software installed, the variable is pre-set to point to the device containing the software. Otherwise, the default value is null. |
| boot_file | Sets the file name to be used when a bootstrap requires a filename. The default setting is null. |
| boot_osflags | Sets additional parameters to be passed
to system software. The default setting is 0 null. OpenVMS boot flags. Tru64 UNIX boot flags. |
| console | This variable routes the console output to either the graphics controller or the serial line port. |
| ewa0_inet_init | Used when booting over a TCP/IP network. The value is normally BOOTP. |
| ewa0_mode | This variable is set to the appropriate
Ethernet media type being used by the system. The possible values are: Twisted-Pair Full Duplex,Twisted-Pair AUI (Default) BNC Fast (for FAST Ethernet controllers) FastFD (for FAST Ethernet controllers that support full duplex) |
| ewa0_protocols | The possible values are BOOTP and MOP. The default is MOP. |
| kbd_hardware_type | This variable specifies the keyboard type, LK411 or PCXAL. The default is PCXAL. |
| language | The language environment variable associates a language to the system. You can have the system prompt you for the language using the following command: >>>set language 0 and then >>>init. Select the desired language. Type >>>init again, then power cycle the system. |
| os_type | Set to the operating system (OS) running on the system. The possible values are UNIX, OVMS, and NT. |
| pci_parity | The pci_parity variable controls PCI parity
checking at the PCI bridge chip. The new value becomes effective after an init or power
cycle. Possible values are: On - parity checking is performed Off - parity checking is disabled Sniff - parity checking will be on for SCSI controllers (NCR53C810), if present at rev 2. Otherwise, parity checking is off. |
| pkx0_fast | (Where x is the controller letter). A value of 0 sets the SCSI mode to slow (5 Mbps); a value of 1 sets the SCSI mode to fast (10 Mbps). Tru64 UNIX and OpenVMS operating system users also must edit the configuration file and rebuild the kernel. |
