Something like that. We need to make sure we send the proper sequence,
though, or it might break some SMM firmware...
Could you please create proper patch? You're the x86 expert (and I'm not).
I've read that 0xd1 command with 0xdf data is often used to enable A20. But I
don't know when this must be done or what else needs to be done for the SMM
to not break.
You need to send an FF dummy command afterwards, that's all.
