Where are all the BIOS versions?

tjacobs42,

It is located in the bios versions below.

Latitude 5580 Bios

Latitude E5540 Bios

Hi Jesse,

unfortunately not. There you find only older BIOS-versions: the E5540's A18 Bios is from May(!), and the 5580's is the older 1.7.5.

Seems they have removed the new BIOSes, maybe there is a problem with them?

Updates have disappeared from the support.dell.com page before and reappeared later, seemingly due to random glitches, so that could be the cause here.  Or there have been reports that in some cases, Intel's updated microcode causes spontaneous reboots, so the updates may have been pulled pending an updated microcode that fixes the security vulnerability without introducing that bug.

Yeah, I was looking for the BIOS Update 1.8.1 and the link only displays the following text:

<ADMIN NOTE: Broken link has been removed from this post by Dell>

The file you are attempting to download is no longer available, and may have been updated or replaced with a newer version. Please visit the Drivers and Download page and try your search again.

It would be nice, if DELL would comment why they remove the files – and actually before they do so!

Updated Jan. 22

We have now identified the root cause of the reboot issue impacting Broadwell and Haswell platforms, and made good progress in developing a solution to address it. Based on this, we are updating our guidance for customers and partners:

• We recommend that OEMs, Cloud service providers, system manufacturers, software vendors and end users stop deployment of current versions on the below platforms, as they may introduce higher than expected reboots and other unpredictable system behavior.

• We also ask that our industry partners focus efforts on testing early versions of the updated solution for Broadwell and Haswell we started rolling out this weekend, so we can accelerate its release. We expect to share more details on timing later this week.
• For those concerned about system stability while we finalize the updated solutions, we are also working with our OEM partners on the option to utilize a previous version of microcode that does not display these issues, but removes the Variant 2 (Spectre) mitigations. This would be delivered via a BIOS update, and would not impact mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown). 

We believe it is important for OEMs and our customers to follow this guidance for all of the specified platforms listed below, as they may demonstrate higher than expected  reboots and unpredictable system behavior.  The progress we have made in identifying a root cause for Haswell and Broadwell will help us address issues on other platforms. Please be assured we are working quickly to address these issues.
