The Dell Exx1x SGN ACPI Problem

Hi Members of the forum,

im writing down in here since i didnt find any more information related to the problem.

Im talking about the necesity to press Shift+Fx to toggle ACPI support for example, in SGN (SafeGuard Enterprise), to boot on to the machine, in the Dell Models.

i know of the existance of:

http://www.sophos.com/support/knowledgebase/article/111562.html

and, as its says "a probable bug on Dell BIOS",

and some of the community posts, that changing the motherboard has caused the issue to appear in a machine that didnt had the problem,

the thing is that we did tell our client (we are a sophos partner) that the problem was on the Dell BIOS.

Of course he contacted Dell and they told him that this wasnt reported by the software manufacturer (Sophos), that this is not a Dell Problem, and that is an incopatibility with the Software.

So im asking you, the community and the support guys that roam around here, if you got references to the case numbers, or any other communication ID if you had it with Dell About the problem.

This is because i still havent found a relevant answer if its is the BIOS or the software, and if there were any communication with Dell and Sophos.

Anything you need ill be happy to help!

Cheers,

Ares, Cristian.

Edit: Just so you know, we're working with 5.50.0, not .1 or .8, and the update wont be done unless it does actually fix the problem.

Also the Machines that we tested were 5 variants of the Exx1x Latitude Series.

  • Dear Charles,

    the mentioned issue occurred due to an internal SafeGuard Enterprise function that relied on a BIOS specific call named "TimerTick" (a BIOS call that can be used to i.e. measure a certain timeframe). This BIOS call did not report back as expected on some machines (i.e. DELL xx1x series)/BIOS versions which caused the initial problem.

    Due to the non-reliable working BIOS call, we changed the general process of applying Power-on-Authentication configurations via hotkeys, so we do not have to rely on the "TimerTick" call anymore.

    Details about the changed hotkey procedure has already been posted and can be found in "Advisory: SafeGuard - changes to POA hotkey usage with version 5.50.1" (http://www.sophos.com/support/knowledgebase/article/111562.html).”

    Regards
