Updating BIOS for Meltdown/Spectre on HP computers
Hi all, We have a bunch (around 100) of HP machines over here which we need to upgrade because of the meltdown/spectre problems. How are you going to deal with meltdown/spectre and bios updates? Has someone already updated their client computers? Greetings, Simon
Hi, I updated a couple of Dell machines I own but I did it manually. I was going to post a tweet because I wondered if anyone had any experience with these CPU patches and whether they noticed a performance drop especially using a screen reader. I have seen a couple of benchmarks with specific apps after the CPU patches have been applied, but of course its very subjective.

Hi From what I have heard on the TWIT network and security now it sounds like the threat has been overhyped. Microsoft released patches to mitigate the meltdown threat and will soon release microcode updates to fix spectre, so there will be no need to manually go into the BIOS which is of course very difficult and time consuming to perform on a large network. Intel are apparently making the microcode available to Microsoft and this will be able to update the processors because of a couple of DLL files within windows which make this possible. Curretnly there are no threats out in the wild and even if there was its not very likely that individuals would be at threat. I think waiting for Microsoft to make these patches available is the best option, although it sounds like they might not come through windows update so you would have to visit the catalogue and download them manually then distribute them through your network.
