ace_mode | Boolean | true or false. |
This statement enables the ACE mode if the CHARON-AXP license permits it. If this statement is omitted from the CHARON-AXP 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-AXP log file displays the status of the ACE option.
The ACE mode is disabled when the host system does not meet the minimum physical requirements for this operation. If the emulator appears to not run at its normal performance, check the log file for a change in the ACE mode and verify that sufficient host resources, especially memory, are available.
The ACE mode can be additionally calibrated with "set ace" directive and the following parameters:
Parameter | Type | Description | |
|---|---|---|---|
| cpu_architecture | Text String | Specifies the architecture of the virtual Alpha CPU. Can be one of the following: EV4, EV45, EV5, EV56, EV6, EV67, EV68 Example:

| container | Text string | Specifies the name of a file in which CHARON-AXP stores an intermediate state of its Flash ROM. This state includes, for example, most of the console parameters. By default it is left unspecified.
Example:

| system_name | Text string | This parameter allows Allows changing the system name, for example:
| ||||||||||||
| system_serial_number | Text string | Allows changing the system serial number, for example:
Any sequence of characters can be used as a serial number. Sequences longer than 16 symbols are truncated to 16 symbols. Serial Numbers should be according to DEC standard: 10 characters. First two characters are capital letters, remaining 8 characters are decimal digits. By default it is set to SN01234567 | ||||||||||||
| dsrdb[0], dsrdb[1] | Numeric | DSRB - Dynamic System Recognition Data Block. These parameters allow changing the emulated hardware model type. Example: | ||||||||||||
it is recommended to specify the full path to this fileset rom dsrdb[0]=1090 |
Sets Console and PAL code versions in the following way:
| Function | Command | |
|---|---|---|
| Set SRM Console version to X.Y-Z |
| |
| Set OpenVMS PAL code version to X.Y-Z |
| |
| Set Tru64 UNIX PAL code version to X.Y-Z |
|
Example:
set rom version[0] = 7.3-1 version[1] = 1.98-104 version[2] = 1.92-105 |
