I have a HP Pavilion dv5224ea laptop on which I have Windows 7 installed. I recently decided to go to the drivers page at HP.co.za and saw that under Windows Vista Drivers (There are no Windows 7 drivers as HP does not support Windows 7 on my machine) that there was a BIOS update.
Now, do I need bother to update the BIOS? Is there any way to backup/restore the BIOS if the update fails? The one thing is that the driver page says that it only compatable with Windows XP & Windows Vista, does this matter?
EDIT: What will I gain from upgrading? Could I, for instance, get hardware virtualisation or TPM (Trusted Platform Module)?
