On Tuesday, HP pulled its softpaqs BIOS updates with Intel's patches from its website, and on Thursday will release a BIOS update with a previous version of Intel's microcode.
Intel has prepared microcode updates for OEMs like HP and Dell that don't trigger the reboots, but also don't contain its patch for Variant 2, while leaving in place mitigations for Meltdown Variant 3 and Spectre Variant 1.
Personally, I have seen one other method described by Felix Schwarz in his doc “Flashing a Dell Bios with Linux)” but this will require to boot using a boot floppy image to flash the bios and normally this will require direct access to the system or at least a remote console.
The above method can be performed remotely and doesn’t require anything special besides a ssh connection.
To update any OS drivers, you will have to use other methods like the Dell Repository Manager or the Lifecycle Controller. Most might not even list “I like long walks on the beach and Dell Power Edge R730s with Intel X710 10Gb NICs” on their Tinder profile.But then again, you might be a homelabber who’s stoked to have scored one of those Power Edge R710s on e Bay for ridiculously cheap or you’re a Sys Admin whose proposal for one of those badass new four-socket Power Edge servers got surprisingly approved. It’ll take about 60 minutes (depending on how many updates it needs) to automatically update everything. You should also thank Dell for not locking these ISOs down to just customers with active warranties & support (looking at you, HP).Armed with this information you now need to get the BIOS version want to upgrade / downgrade. Scroll down the list to find a directory matching the System ID from the previous step. be sure to remove the “reboot=bios” from your kernel line.and look for the bios version that you want to upgrade/downgrade to In my case my directory is named: system_bios_ven_0x1028_dev_0x0209_version_a14/ my system ID IS 0x0209 and the version of bios i wanted was A14. Now that you are done updating /downgrading we would need to tell the system to do a cold reboot which is what is needed after doing a bios update. I used this method to update the BIOS of my dell xps m1330 ( and downgraded it once) and it worked fine without any ( as we Nigerians will say) Whahala or problem. If unsure, check with your Dell support representative before doing this.We will be using get System Id to get the system ID and dell Bios Update to perform the actual update.If the process isn’t automated in some way, it can also take a lot of your time and a lot of downtime for that server. As the server is booting up, boot into the BIOS Boot Manager (press F11) and click on “BIOS Boot Menu”. Luckily, there’s an easy way to automatically update all of the firmware, drivers, and BIOS on your Dell Power Edge server via a bootable Linux ISO image. Once finished, plug the bootable USB drive you created into any of your server’s USB ports. After some initializing, you should be able to choose what device to boot into. so that we wont need to been adding sudo infront of every command.so first copy and paste this in terminal from the above output my system ID is 0x0209.
