Without going into a long drawn out explanation, you can use something like bginfo.exe to accomplish this.
Basically, you can add bginfo.exe and the config file to "WinPE 2.x Additional Files" in the Boot Disc Creator.(C:\Program Files\Altiris\Altiris Agent\Agents\Deployment\Task Handler\bootwiz\bootwiz.exe)
Use this link for information about BGInfo: http://technet.microsoft.com/en-us/sysinternals/bb897557
Next, you would need to change your runagent.bat file in C:\Program Files\Altiris\Altiris Agent\Agents\Deployment\Task Handler\bootwiz\oem\DS\Winpe2\x86\Base and/or C:\Program Files\Altiris\Altiris Agent\Agents\Deployment\Task Handler\bootwiz\oem\DS\Winpe2\x64\Base
This file is read-only by default, so first make a backup and then edit the file (after changing the attributes from read-only). This is the "batch file" you see running when the Automation screen first appears.
Add a command like the following into the batch file
ECHO Starting BGInfo
"%systemdrive%\bginfo.exe" /i"%systemdrive%\<YOUR CONFIG FILE NAME HERE>.bgi" /silent /nolicprompt /timer:0
I like to put that command towards the end of the script but before the pectacgent is started.
Thats it, save the runagent.bat, Recreate your Preboot from the console, and enjoy having some more information displayed in Automation.
