Why wrong? It just doesn't tell for what clock source it is. Or clock input? even that's not clear to me. But I agree that it doesn't seem to apply in your case. PEG is PCIe too, but not a feature of your SKU, AFAICT. Nico -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
