Thanks for clarifying. It was a little early :) Skip it for read_resources. Disable, write, then enable using conf1 pci config accesses for set_resources. Otherwise use the default. I think that will allow you to use mmconfig accesses everywhere else. Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
