XPS 8500, BIOS A13, big performance hit

Last weekend I updated my XPS 8500 to A13 because it was marked "Urgent".  Since then the machine has slowed very noticeably. (boot time is about the same).  I would like to roll back to A12 to verify this, but when I try to install A12 it won't let me saying A12 is an older version.  How do I go back to A12?

thanks

What happens if I go into the BIOS and reset it?  Will it put the Bios version back to how it was shipped?

The rollback is not possible. Resetting the BIOS will simply reset A13 to its defaults.
What operating system? List all of the currently installed Dell software.

A11 + USB drive + Rufus + A11.exe /forceit

Make DOS bootable drive, boot with it and write command.

simsim986,

Have successfully done those above instructions on the XPS 8500? Or had you done a similar operation on a different Dell model computer?

Yes, I have XPS 8500 and changed BIOS on it from A13 to A11. Computer performance restored.

Well spelling counts so you need a space  A11.exe/forceit won't work but A11.exe /forceit might.  I've only seen this with legacy bios however never with UEFI bios.
