Yes, the PCI id is correct. You cannot see them is because they
are hide by BIOS. I've already sent a request to BIOS team to
unhide them. I will let you know the updated BIOS version,
once I get feedback from them.
BTW, I've verified the PCI id in BDX-EP with corrected BIOS. IMCs
counter works well. EP and DE are same for iMC0CH0 and iMC0CH1.

Thanks,
