Following Dell, HP and ASRock also announced an emergency announcement that the recently updated BIOS, which added a new microcode to fix specter vulnerabilities, was completely withdrawn from the Intel platform. HP said it will roll back to the previous version of microcode on January 25, allowing users to selectively downgrade or wait for a new BIOS.
ASRock did not say whether you can roll back, maybe because they were distributed on January 22 (which is more depressed?) The motherboard update, the user base is still quite small. Of course, the products are still quite wide-ranging, including Z170 24, H170 14, Q170 2, B150 23, C232 2 (with E3 v5), H110 29, Z270 15, H270 5, B250 6 Models, Z370 10 models, X299 9 models, a total of 139 models.
It is learned that the background of this incident is that Intel updated the microcode to the OEM in order to make the BIOS block off Specter vulnerability V2 attacks (branch target injection), but afterwards found that led from the SNB is the second generation Core Duo to the latest Coffee Lake eight generations Core and other platforms frequently restart.
Currently, AMD Ryzen’s 300 Series motherboards (such as ASRock) have also started BIOS updates to plug Spectre and have not yet received a bug report.
