XPS 8300 BIOS A06 or A07?

I have a "sandy bridge" code when I run CPU-Z.  Is there a new Bios for this that has the UEFI instead of bios, and will this still run all my programs?  I'm have a resolution breakup constantly with "display driver stopped working, now has recovered.  I have a Radeon 5770 HD card in it, but drivers are not available for this, or does this card take the UEFI.  It worked good with my windows 7, but windows 10 display is action up, sometime I have to re-boot several times to get it to work again.  My MSINFO32, does not work don't know what, and I don't know how to fix it with windows 10.

There is no UEFI support on A06. I have that card in my XPS 8300 and it works fine with Windows 10 TH2 (Clean Installation).

Problem XPS 8300 post hang (no boot hang) with nvidia quadro K4000

Tried all ends at BIOS problem... dell...

Reviving a old thread for sanity. I'm helping someone who is having graphics card compatibility issues with this machine and I was looking for an updated bios and I keep seeing these instructions, but taken completely out of context.

The instructions were given to someone who has the A07 bios on a board and is trying to extract it.

See the first line: To extract YOUR A07 BIOS follow the below:

This command does NOT magically generate the A07 firmware out of thin air.

"afuwin.exe A07.ROM /O" - All this command does is backup whatever bios you currently have running on your machine to a file that you are calling A07.ROM

Nice, but how do i update it now?
