Question

Why does the system does not resume from Standby mode properly after installation of Sophos SafeGuard Disk Encryption?

Answer

As of Sophos SafeGuard Disk Encryption 4.60.0, you may apply the following setting during installation or update, if your system does not resume from Standby mode properly (e.g. not resuming at all or restarting):

In order to address the Standby problem, a property variable called EMEM='offset' needs to be included in the setup routine.

Setup EMEM=1024 advises the Pre-Boot code to pass its parameter block 1024 bytes below the boundary that is indicated in the BIOS.

Example:

msiexec /i c:\Install\sde.msi /qn /L*vx C:\Install\SDE_INST.log CFGFILE=C:\Install\Install.cfg ADDLOCAL=SDE,Encryption,SGSAL EMEM=1024


EMEM has a valid range from 1 to 16383 bytes.


Please note that you may configure this offset only during installation or migration. The value can be found in the registry under the same value name. It serves for information purposes only. Subsequent changes of this value have no effect!

For more information about installing Sophos SafeGuard Disk Encryption using the command line, please refer to the user manual under the chapter titled "Central Installation". The migration process is described in chapter five "update".

Please note that a configuration file (respectively migration file) is necessary to install (respectively update) Sophos SafeGuard Disk Encryption unattended.

If you do not want to install Sophos SafeGuard Disk Encryption unattanded you can use the following process:

Open a CMD windows. Go to the path where the Sophos SafeGuard Disk Encryption install files are stored.

Type setup.exe EMEM=1024




The Sophos SafeGuard Disk Encryption will go through the normal installation process.
