Re: [dmidecode] [PATCH v2 1/1] dmioem: HPE OEM Record 199

[Jerry Hoemann]

Jean,

I'm not seeing this particular decode on the samples that I have
tested with.  Looks like you may have picked up some samples that
I don't have.  (note, I am not seeing an AMD EPYC 7451 on my tests..)

Could you email me the binary dumps whose decode you question?

thanks

Jerry
