HP t5740 and t5745 thin clients hang during DOS imaging

Issue/Introduction

 

Resolution

Problem

The HP t5740 and t5745 Thin Clients have an issue with DOS based image capture and deploy using rdeploy and rdeployt.   That symptom is a hang shortly after the rdeployt or rdeploy imaging engine starts to capture or deploy an image on the thin client. 

Environment
Deployment Solution 6.9 SP3.

HP thin client 57xx series.

DOS automation.

Rdeploy.

Cause

The Dos Protected Mode Interrupt handler (DPMI) that is internally bundled with rdeployt and rdeploy is not compatible with the t5740 and t5745. The attached version of rdeployt was built with a DPMI handler that is compatible with the t5740/t5745. 

Resolution
 

To use when imaging from the Deployment Solutions GUI:

 

1. Download '57540_5745_DOS_FIX.zip' and extract to a temporary location on the Deployment Solution system. (E.g. 'C:\temp')

 

2. Locate the first copy of the DOS 'rdeployt.exe' file in the '<install drive>\Program Files\Altiris\eXpress\Deployment Server\Rdeploy\DOS' directory

  

3. Make a backup copy of the existing 'rdeployt.exe' by renaming it to 'rdeployt.bak'

 

4. Copy the new 'rdeployt.exe' that was extracted in step one to  '<install drive>\Program Files\Altiris\eXpress\Deployment Server\Rdeploy\DOS'   
   
5. Locate the second copy of the DOS 'rdeployt.exe' file in the  '<install drive>\Program Files\Altiris\eXpress\Deployment Server' directory

 

1. Note the directory path may look a bit different under older DS versions.

 

2. Also note the directory structure does not explicitly include the word DOS, however the 'rdeployt.exe' file is used for DOS. 

 

6. Make a backup copy of the existing 'rdeployt.exe' by renaming it to 'rdeployt.bak' 
   
7. Copy the new 'rdeployt.exe' that was extracted in step one to  '<install drive>\Program Files\Altiris\eXpress\Deployment Server'
   
8. When creating  a DOS imaging job, select the 'rdeployt' imaging engine. Note: In DS 6.9 versions, rdeployt is the default imaging engine. 

 

To use when imaging from a bootable device such as a USB flash drive:

 

1. Download the attached file.

 

2. Copy the new 'rdeployt.exe' to the bootable media and proceed with imaging using the same command line parameters as used previously. 

 

Note:

The attached rdeployt was validated on HP t5740 and t5745 thin clients using Deployment Solutions 6.9 SP3.  It has not been validated on other platforms or on other versions of Deployment Solutions.  Customer wishing to use this modified version of rdeployt on other devices or other versions of deployment Solutions should first verify it meets their needs in a non-production environment.“
