To download ROM updates for other devices then browse here.

They can also be found on HP's site using the Software and drivers download search function.

All external links worked when I updated this page, I have also downloaded each one and have run an antivirus scan on each to make sure they are clean. I obviously cannot guarentee that the are still virus free or active.
