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

Rober

HEllo

this is bios 2.45 for Linux for z640

ftp://ftp.hp.com/pub/softpaq/sp88001-88500/sp88254.tgz

 

this is BIOS 2.47 for Linux

ftp://ftp.hp.com/pub/softpaq/sp93001-93500/sp93481.tgz

 

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.

 

bye
