Re: BIOS Downgrade II

HP Recommended

Hi All,


We are using the Z640 with RedHat 7.4 now, the current BIOS version is 2.47, due to some reason, I need to downgrade the BIOS version back to 2.45, could anyone know how to do that in simple, thanks.


Best regards

this is bios 2.45 for Linux for z640


this is BIOS 2.47 for Linux


for Windows BIOS the softpaq are .exe version but I guess the BIOS bin file is the same, but I'm not sure


You can even try to update/downgrade the bios via network, just boot z640, press F10 and select Update System BIOS, you can load the bin from USB key or via Network.
