HP 8300 Elite SFF Bios Downgrade

HP Recommended
HP 8300 Elite
Microsoft Windows 10 (64-bit)

Hi all,

 

I have recently upgraded my bios version on my HP8300 Elite to Version 3.07 to find some issues booting fron a particular type of HDD.

What I would like to know is how to downgrade the Bios to Version 2.99 the last known working version.

 

Thanks in advance.

 

Dave

In checking the BIOS update files for v 3.07 it states: NOTE: Due to security changes, after loading this BIOS, older versions cannot be installed.

It would appear to be prevented in going back to V 2.99

I did read that, but there must be a way.

otherwise I am going to have to replace the motherboard.
