    I am really curious about how they are going to fix Spectre-related vulnerabilities.

    For Spectre bios has to be updated. That falls on motherboard manufacturers.

    All motherboards from 2000-2018

    Haven’t seen anything for my Gigabyte board.

    @Mikorist: Your post made me search around for my own MoBo.

    I haven't found anything as of yet. (Asus P8Z77-V PRO)

    I think you're correct. This issue will probably be pushed off onto the MoBo manufacturers via a BIOS update.

    @taviruni Compared to last years release I'm seeing specific updates for Ivy Bridge, Haswell, Broadwell, Skylake, Kaby Lake, Coffee Lake & Gemini Lake CPUs.

    Out of the 94 files only 19 of them are different.

    I did, but that result still doesn't mean that you're safe from Spectre. The powershell script will tell you if you are.

    @taviruni You're still vulnerable to Spectre.

    If the VMware program did work for you then I guess it didn't update your microcode to a Spectre patched version.

    You can download any live-dvd linux distro - boot and test PC to Spectre and Meltdown as well
