This morning I was referred to this site with microcode updates: https://downloadcenter.intel.com/download/27431/Linux-Processor-Microcode-Data-File
But it claims to have microcode updates going back to the venerable "P54" Pentium-90 and "P55" Pentium-233 MMX. I'm confused. We're not told these i586 CPUs, which don't do speculative execution, are susceptible to SPECTRE. I don't recall reading microcode *could* be updated on them! I was afraid microcode for the Pentium-3 family, a few of which I *can* still run, would be neglected, but I don't know what to make of all this. Making sense of Intel's file names as relates to particular hardware is also obscure to me. -- Paul Rogers paulgrog...@fastmail.fm Rogers' Second Law: "Everything you do communicates."
