Where is the data held in Max 3.0

Question

Hi,
Not sure if this right place to post this but as MAX 3.0 was installed with labVIEW 7.0.....here goes..
With Max 2.0, the data assoicated for GPIB, VISA and IVI was held in two places, IVI.INI and VISACONF.INI.
Now Max 3.0 arrives, so where has the data gone. There still is an ivi.ini but it doesn't contain all the data. Visaconf.ini still seeems to be the same.
I can still see most of the settings for drivers, logical names etc when I launch MAX 3.0, that used to be in my old ivi.ini file. So where does it store them now.
Also, what has happened to the default settings that used to be defined for a logical name?
Looking, in the MAX folder there are a load of LV VI's in the MAX\Assistants\LVCGen, what are these used for
I have looked, at the Max help but its a bit vague.
Can anyone shed some light.

Hello Ray,
With installation of LabVIEW 7.0, you have also installed MAX 3.0 and IVI Compliance Package 2.0. The IVI Compliance Package (ICP) 2.0 is a software package that contains IVI class drivers and the support libraries necessary for the development and use of applications that leverage IVI instrument interchangeability. The IVI Compliance Package also is based on and is compliant with the latest version of the instrument programming specifications defined by the IVI Foundation.
One of the most prominent changes between previous IVI products and the IVI Compliance Package is the way that the IVI Engine, IVI MAX configuration utility, and other IVI products included in the IVI Compliance Package access and store configuration information. The Configuration Server provides
a database for storing configuration data and an API for accessing this data.
This database is called the Master Configuration Store. Various IVI products have been redesigned to work with the Configuration Server instead of the previous method, which involved using the ivi.ini file.
If you have any configuration information stored in the ivi.ini file, the installer converts the existing ivi.ini data into a new format that is used by the Configuration Server and stored in the Master Configuration Store file (IviConfigurationStore.xml). This conversion process, which takes place when you install the IVI Compliance Package, removes the converted items from the original ivi.ini file as it places them in the Master Configuration Store database.
The installer also creates a backup copy of the ivi.ini in the same directory as the original ivi.ini.
If, after you install the IVI Compliance Package, you run an older specific instrument driver installer that adds entries to the ivi.ini file, you can convert the newly installed configuration data by running MAX, which monitors the ivi.ini file for changes. If MAX detects any changes, it launches a conversion utility automatically before loading the configuration from the Master Configuration Store file. Also, you can run the converter utility manually by selecting Start�Programs�IVI�Tools�INI to XML Converter.

You can also find more information in the ICP Release Notes.
I hope this helps.
