<p>I’ve been a bit quiet here recently because I’ve mainly been working with my business laptop currently running Windows 7. You can see more about this on my other blog – [Much Ado about IT][1]. However, the power supply on that died recently so I’m back to my trusty desktop which runs OpenSUSE 11.0 24×7. I managed to get hold of an upgraded CPU for this a while back but I’ve not really had an incentive to upgrade till now. The new CPU supports hardware virtualisation but I need to enable this in the BIOS. Of course, this machine (based on an ASUS A8N-SLI Deluxe motherboard) has an old BIOS that doesn’t allow me to turn on these features so I needed to upgrade to the latest (v1805). But, I only run Windows under VirtualBox on this computer and I don’t have a floppy drive so updating a BIOS is no trivial matter! After some Googling, here is the answer:</p> <ol> <li>Install the coreboot-utils package</li> <li>As root, at a command prompt, run “flashrom” to check that your chipset is supported for writing</li> <li>Extract the .bin file from the archive containing the updated BIOS image</li> <li>Make a backup of the existing BIOS with “flashrom -r backup-bios.bin”</li> <li>For the paranoid, try writing that backup back to the BIOS with “flashrom -wv backup-bios.bin” to ensure there are no errors. Reboot at this point for the really paranoid</li> <li>Now flash the new BIOS with a similar command to step 5</li> <li>Reboot and check that the new BIOS is OK If you get an error from flashrom saying that the new BIOS is the wrong size, you may have had a problem unpacking the bin file from the archive as I did. Unpack the whole archive to a folder. If flashrom doesn’t work for you, there are lots of other ways – I like using GRUB to boot from a floppy disk .img file – very “Linuxy”.
