Debugging CPU errors. I have two notebooks: 1) HP EliteBook 745 G5 with Ryzen 5 PRO 2500U It runs 1.03.01 BIOS with 0x0810100b microcode and suffers from MCE logged CPU errors. 2) MateBook D with Ryzen 5 2500U It runs 1.12 BIOS with 0x08101007 microcode and MCE doesn't report any CPU errors. I wanted to downgrade microcode on HP EliteBook and upgrade microcode on MateBook to see if that makes a difference for them. For that I need to: 1) Dump old microcode from MateBook & run it on EliteBook 2) Dump new microcode from EliteBook & run it on MateBook -- Rafał
