The default VAX CPU mode is determined by the specific CHARON-VAX product license.
Parameter | ace_mode |
---|---|
Type | Boolean |
Value | true or false. |
This statement enables ACE mode if the CHARON-VAX license permits it. If this statement is omitted from the CHARON-VAX configuration file and the license permits it, "true" is the default. Otherwise "false" is the default. For test purposes the ACE mechanism can be disabled with:

The CHARON-VAX memory subsystem is permanently loaded and has the logical name "ram".
size
Parameter | size |

Type | Numeric |
Value | Size of emulated memory in MB. |

CHARON-VAX maintains its time and date via the "toy" (time-of-year) component. In order to preserve time and date while a virtual system is not running, the TOY component uses a binary file on the host system to store date and time relevant data. The name of the file is specified by the “container” option of the "toy" component.
container
Parameter | container |
---|---|
Type | Text string |
Value | Specifies a name of a file in which CHARON-VAX preserves time and date during its “offline” period. This file also keeps some console parameters (such as default boot device). By default it is left unspecified. It is recommended to specify the full path to the file |
...
The System Flash ROM file conserves specific parameters between reboots.
container
Parameter | container |
---|---|
Type | Text string |
Value | Specifies the name of a file in which CHARON-VAX stores an intermediate state of its Flash ROM. This state includes, for example, most of the console parameters. By default it is left unspecified. It is recommended to specify the full path to the file |
Example:
set rom container="/charon/my_virtual_system.rom" |
EEPROM
container
Parameter | container |
---|---|
Type | Text string |
Value | A string specifying a file name to store content of EEPROM .for VAX 6000 series Example:
This command enables EEPROM parameters (e.g., default boot drive) to be automatically saved to a specified file. The EEPROM file is created in the directory in which CHARON-VAX starts and is created or overwritten each time any parameter relevant to EEPROM content is changed. It is recommended to specify the full path to the file |

Those models boot automatically if correct boot flags are set (and saved in the VAX console files) using the following command:
halt
Console Parameter | halt |

Description | Determines whether the MicroVAX3100, VAXstation 4000, VAX6310 and VAX 4000 boot automatically if correct boot flags are set (and saved in the VAX console files). The value is Example:

...
The ROM of the MicroVAX II, MicroVAX 3600, MicroVAX 3900, VAXserver 3600 and VAXserver 3900 does not allow the VAX console to accept the command setting "auto-boot". Instead, automatic boot on startup can be specified in the CHARON-VAX configuration file as follows:
bdr boot
Parameter | bdr boot |
---|---|
Type | Text string |
Value | Determines whether the MicroVAX II, MicroVAX 3600, MicroVAX 3900, VAXserver 3600 and VAXserver 3900 boot automatically if correct boot flags are set (and saved in the VAX console files). The value is Example:
