XPS 420 Dimension Windows 8

I have upgraded to windows 8 from the original OEM of Vista. My question: Is there an update to the BIOS of A07, 25/02/2009?  I would think there would be but I cannot find if there is one.  All is running well but I'm thinking of trying 8.1 but it will not upgrade for some reason and thinking perhaps there may be some issues with the current old BIOS?

Any help or suggestions are very welcome.

Cheers

Hi hankanen,

That appears to be the most recent version.

Even if there was a BIOS update, you would not need to install it to upgrade the OS. BIOS updates are usually for correcting or adding hardware support.

Inspiron E1705, Win 10 CU Pro 32-bit
Dimension 9100, Win 10 AU Pro 32 bit

Re: XPS 420 Dimension Windows 8

thanks for your reply; I was afraid that would be the case. I would have thought that a newer version would have been made.

Dell won't update such an old system to support Windows 8 and UEFI/Secure Boot.

They won't even release the update for the XPS 8300 or XPS 8100 despite the systems having a lot of similar hardware to the supported XPS 8500.

Windows 8.1 and Windows 8 should have the same system requirements however.

Re: XPS 420 Dimension Windows 8

I think DELL should support machines that are a minimum of 5 years old to a point.

However. having said that I have been running windows 8 for about 6 moths now with no issues, i was hoping to take 8.1 our for a test drive but perhaps not! when I bought the system it came with VISTA Ultimate 32 bit, although it will run as 64bit, I then upgraded it to Windows 7 and all was good, then to Windows 8 pro+media centre and all is still good.

i agree, they cant keep changing system requirments with each release/upgrade.

Wait until the final version of 8.1 comes out. I have the 64 bit version on a separate hard drive on my 420 and it's fine, but the final version will be more a finished product and will preserve your current files and settings. The bios was not a problem especially using the iso file burned to dvd. You should however install the 64 bit version of windows 8 if you have not done that already. The 420 can run it You would have to download and burn the win 8  iso file to dvd to switch to 64bits. You have to have a dvd burning program available since win 8 doesn't have one.

I have a Dell XPS 420 as well.  It is running Windows 7 Home Premium (64-bit) like a champ, but I am considering upgrading to Windows 8.1 Pro (64-bit).  This article explains why some Core 2 Quads (such as my Q6600) and their motherboards (such as Intel DP35DP) a won't work with a required instruction set: "Compare Exchange 128 CMPXCHG16b".  LINK: http://www.pcworld.com/article/2058683/new-windows-8-1-requirements-strand-some-users-on-windows-8.html

Windows 8.1 requires this instruction set, but Windows 8 didn't, leaving some machines stranded without the possibility of upgrading.

So, will my Dell XPS 420 support Windows 8.1?  I would rather not buy it and try it to find out it doesn't work...  Thanks for your support.

Install a Q9300. (You can buy one on eBay for under $100.) The Q9300 supports the instruction you reference.

For the record, I have been using 8.1 for a couple of months now and the UI is clunky. Unless you have a compelling reason for updating, I suggest staying with 7 and saving your money.

The "unsupported" CPUs can run Windows 8.1 32-bit as far as I know; it's the 64-bit version that's incompatible.
