Dell E5550 and Sophos 7.0.2.23 installation error 5017

Question

I'm getting Error 5017 Incompatible hardware configuration while trying to install. 
 The BIOS is set to AHCI and the drivers for the raid are not installed. 
 
 Is there a reason why the installation would think the RAID drivers are installed yet they are not. We've checked the registry and can't find anything there etc.

We have installed SGN7 on many Exx50 machines without problems. The SATA mode needs to be set to AHCI in BIOS as a prerequisite. You said you did that. We also had some rare cases where we got error 5017 although AHCI mode was set. In these cases we had to override the SATA RAID check. You need a customized poacfg.xml file in order to do this. A POACFG.XML can be download from the ftp server described in this article: https://www.sophos.com/en-us/support/knowledgebase/65700.aspx Download file POACFG_7_00_0_105_and_above.xml from there. Edit the XML file and remove the SATA RAID check for the 5550 model by deleting this section: 7.00.0

WARNING "RAID is not supported, the value of the SATA Operation setting must be switched to AHCI in the BIOS of this hardware",ABORT Now follow the instruction from the article above to use the customized file for installation. Make sure you specify a correct absolute path to the poacfg.xml file, e.g. C:\SGN\poacfg.xml or C:\TEMP\poacfg.xml. It depends on where you store the file locally. Even if the file is stored in same folder as the MSI file, you have to specify the full path to the file. -Holger
