Re: Has XPS 8900 BIOS version 2.2.1 been updated?

Jump to solution

Dell has released a new version of the BIOS (here). It still has the same version number (2.2.1), but has a release date and "last updated" date of February 6, 2018. I think I'll wait a little while before installing this. Just in case...

Re: Has XPS 8900 BIOS version 2.2.1 been updated?

Since the changelog and version number (2.2.1) did not change, and since the size (5780 KB) and digital signature (signed 12/11/2017) are the same as the old one previously published TWICE during last month without change, ...

... i assume they just made the old (and bugged) version available, including the (noyt fixed yet) buggy Intel microcode update on Spectre (Variant 2), CVE-2017-5715 that :

- Dell is still saying "URGENT do NOT deploy anymore" on their own KB (see 01/22/2018 updates on both SLN308587 https://www.dell.com/support/article/us/en/19/sln308587/microprocessor-side-channel-vulnerabilities-... and SLN308237 on https://www.dell.com/support/article/us/en/19/sln308237/dell-client-statement-on-intel-me-txe-adviso... )

- and Intel says the same on website (see https://newsroom.intel.com/wp-content/uploads/sites/11/2018/01/microcode-update-guidance.pdf and https://newsroom.intel.com/news/root-cause-of-reboot-issue-identified-updated-guidance-for-customers...)

- and Microsoft did release an out of band critical update to disable any windows usage of the faulty microcode update pending a new intel patch, and Dell BIOS patch, with KB4078130 (from https://support.microsoft.com/en-us/help/4078130/update-to-disable-mitigation-against-spectre-varian... and https://www.catalog.update.microsoft.com/Search.aspx?q=KB4078130 ).

As owner of an XPS 8900 with faulty BIOS 2.2.1 that bricked my Motherboard and CPU, i cannot recommend to install this BIOS update, even if someone at Dell did push back the wrong publish button, it is NOT FIXED YET.

So are we saying not to download this new February 2018 version of 2.2.1?  I did download the 10 Dec 2017 version back in December and my system appears to still be working properly.  It is a shame Dell does not provide more background information on these issues and I have to go to this site to find the facts.

Dell has updated their knowledge base article (here). Part of what it now says is:

 

Patch Guidance
Update 02/05/2018
Dell has received updated Intel microcode for select platforms to mitigate against the Spectre (Variant 2) vulnerability CVE-2017-5715. Dell has started to deploy the new BIOS updates for these platforms listed in the table of Dell Products Affected below. Other BIOS updates for listed affected platforms will roll out over the coming weeks.
All customers with an affected platform should download the latest BIOS update listed below, even if they have deployed an earlier BIOS version for this vulnerability. Those who have disabled the microcode patch using an OS configuration option should re-enable it manually after applying the BIOS updates.
As a reminder, the microcode update is required for Spectre (Variant 2), CVE-2017-5715. The Operating System patches provide mitigations to Spectre (Variant 1) and Meltdown (Variant 3) and are also required.

 

I haven't updated yet, but probably will later today or tomorrow. I just want to wait awhile to see if people start having major problems with this BIOS update like some had with the last one (computers becoming unusable...).

In the last few minutes I checked my Dell Help  & Support window and it still shows I should still download the "URGENT" Bios Version 2.1.10 dated 2 Aug 2017 update.

My 8900 started freezing in August. Hours of dell support and after sending the unit back to dell twice its still down.

Where is dell with this?   I've read all the posting and I don't see a solution from dell.

 

The new bios dell posted on 2/5/2018.

Do I need to reinstall windows 7 after updating the new bios?

What are the steps in installing the bios when windows is not loading?

Download and run rufus

https://www.thomas-krenn.com/en/wiki/Creating_a_Bootable_DOS_USB_Stick

Follow instructions in creating dos bootable USB above.

Run the BIOS update utility from DOS environment if Legacy Boot Mode(Non-Windows users).
1. Copy the downloaded file to a bootable DOS USB key and rename the file name to less than or equal to 8 characters (8.3 format), like 8900A09.exe.
2. Power on the system, then Press F12 key and Select "USB Storage Device" and Boot to DOS prompt.
3. Run the file by typing copied file name where the executable is located. 
4. DOS System will auto restart and update BIOS while system startup screen. 
5. After BIOS update finished, system will auto reboot to take effect.

I have not tried the above and cannot confirm it to solve this issue. 

I will report back.

did windows load up fine right after installing new bios or did you need to reinstall OS?

I tried booting to dos usb and then running the new bios.  Still stuck at windows screen. Then tried to reinstall windows 7 and it froze.

What did work for me was installing bios from Feb 2017 and then reinstalling windows 7.

Edit:  Failed

I ran dell driver update excluding bios and windows update.  reboot. and stuck at "starting windows" screen.

I didn't have to reinstall Windows.

I ran the BIOS update from within Windows. It updated the BIOS, took a minute, maybe 2. Then the computer restarted and Windows opened as it usually does.

I did the Dec.2.2.1 BIOS update. I didn't have a problem. Then I saw there were people having problems. I saw that Dell  took it down. I was afraid to go back to an early ver. Now there is a new Feb. 2.2.1.I'm afraid to do that one.
