Updating a BIOS from Ubuntu is only possible if the hardware manufacturer provides a custom tool that runs with Ubuntu or Linux. If this is (likely) not the case then you need a BIOS update tool that is installed on a bootable external device (e.g. In the best case an.iso file that can be written on your stick or CD from Ubuntu can be downloaded.

Sadly, generating a bootable device is often done again from a Windows utility that does not run in Ubuntu. If you are lucky the manufacturer provides a DOS-based BIOS update utility that you can run after booting into DOS (or ).

HP offers a utility to update BIOS from a bootable CD-R, however AFAIK this CD needs to be generated from within Windows. In this case, and if you are unable to extract the CD's image from the data provided otherwise, you unfortunately will have to burn your bootable BIOS update medium on another machine that runs Windows. BIOS downloads from HP are restricted and require regsitration to their site. Therefore I am sorry that I can't give you a more precise advice on the procedures involved.

After updating the bios on my dc7800 from v1.04 to v1.35, the ethernet controller is no longer listed in the PCI Devices list. I would like a copy of the v1.04 bios so that I can restore to that version. Is this available anywhere? I've been unable to locate the earlier version anywhere in the HP downloads. As far as I can tell, the dc7800 doesn't have an on-board backup of the earlier version, tho I'd be happy to discover otherwise. Alternatively, has anyone experienced this problem before, and could advise me on how to get the bios to recognise the ethernet controller?
