Summary

This paper attempts to explain how Aex_HW_CPU component of the AeXMachInv.exe gets the information it reports to the Notification Server.


When AeXMachInv.EXE runs, it produces an AeX HW CPU.NSI file in the Inventory folder of the client. This NSI file contains the following XML code:















































There are 4 data items that are gathered for reporting to the Notification Server:
C0 XML data is the name of the processor on which hardware inventory was gathered.

C1 XML data is current clock speed.

C2 XML data is the processor number in the system. If there are multiple processors, then the C data will be listed for each.

C3 XML data is the FSB (File Side Bus Speed).


This data is gathered using various methods.

Determining the Processor Type

Altiris has an internal mechanism for determining the type of the processor. The following is a sample of the data that are returned when the AeX_HW_CPU component runs.


Vendor: GenuineIntel
Family: 1111
Model: 0010
Step: 1001
Type: 00
BrandId: 1001 Intel Pentium 4 processor
These results are compared against the ProcessorDesc.ini found in the Inventory Solution package folder on the client computer.
The contents of the ProcessorDesc.INI file are listed below. Each entry has a header of the format: “00 1111 0010 Intel Pentium 4 processor Special” where the first number (00) is the Type, second (1111) is the Family, and the third (0010) is the model.  The description of the processor follows this header.  If the description has the word "Special" at the end, the [BrandId] section of the returned results is used. In this case BrandID contains

“1001 Intel Pentium 4 processor”


So for this example C0 data we would report "Intel Pentium 4 processor".
Notice, however, that the C0 data in the listed NSI contains “Intel Compatible”. If the processor data is NOT listed in the ProcessorDesc.INI file then “Intel Compatible” is reported even if the name and manufacturer are available via the registry or WMI. Later in this document, a process will be provided describing how to update the ProcesorDesc.ini file.
The data in the ProcessorDesc.ini list must be sorted smallest to largest (binary).

Determining Current Clock Speed

A windows power management DLL file is used first to attempt to get CPU speed.  If the DLL does not exist or if it fails, the registry location HKLM\Hardware\Description\System\CentralProcessor is scanned. On Windows 9x computers timer performance calculations are made.

Once a value is gathered, the value is normalized against the CPUSpeedINI.INI file also found in the Inventory Solution package folder. The contents of this INI file are listed below:
CPUSpeedIni.ini has 3 comma-separated values per line.  The first number is the low range and the second number is the high range. The third number is the CPU speed value that will be reported in the C1 XML data if the CPU speed falls within the low and high range.  The INI file is parsed line-by-line looking for ranges that enclose the determined/calculated CPU speed.

Determining Front Side Bus (FSB) Speed

The C3 XML data contains the Front Side Bus (FSB) Speed or external clock speed. If WMI is available it is used to gather this data. This is gathered using the ExtClock method of the WIN32_Processor WMI class.




Modifying the ProcessorDesc.INI File

There is an internal utility called AeXCPUIdent.exe that can be used to return the header information necessary to populate the ProcessorDesc.ini file. In this example, the C0 XML data reported “Intel Compatible”. The actual processor is an AMD Athlon XP 1700+. To get AeXMachInv.exe to report the correct processor type follow these steps.




  1. Run the AeXCPUIdent.exe utility on the computer reporting “Intel Compatible”. A dialog box appears with data similar to the following:

Processor Info

===========================================

Vendor: AuthenticAMD

Family: 0110

Model: 1000

Step: 0000

Type: 00


BrandId:


  1. The following VB script can be run to return WMI data if you are in doubt on what the processor description in the computer is.

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer)

Set colProcessors = objWMIService.InstancesOf("CIM_Processor")

For Each objProcessor In colProcessors

Wscript.Echo "Name: " & objProcessor.Name & vbCrLf & _

"ClockSpeed: " & objProcessor.CurrentClockSpeed & vbCrLf & _

"Number: " & objProcessor.Family & vbCrLf & _

"ExtClock: " & objProcessor.ExtClock & vbCrLf & _

"Manufacturer: " & objProcessor.Manufacturer & vbCrLf & _

"Description: " & objProcessor.Description & vbCrLf

Next
The VB script will return a dialog similar to the following:




  1. With the data returned from the AeXCPUIdent.EXE and the VBScript, the ProcessorDesc.ini file located in the Inventory Solution package location on the Notification Server can be modified.

  1. Once the Inventory Solution package update gets pushed out to the clients, those client computers containing this kind of processor should now report accurately.
