Re: BIOS Downgrade II

Unknown

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

Re: BIOS Downgrade II

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
