マイクロコードのリビジョン確認

# modprobe msr # x86info --microcode Found 1 CPU -------------------------------------------------------------------------- Family: 6 Model: 13 Stepping: 8 Type: 0 Brand: 6 CPU Model: Pentium M Original OEM Feature flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat clflsh dtes acpi mmx fxsr sse sse2 selfsnoop acc pbe Extended feature flags: est tm2 L1 Instruction cache: :Size 32KB 8-way associative. line size=64 bytes.

他にも色々拾えて面白い感じ。
