Thanks. I am always using cf8/cfc, but I'm calling different functions. I've never understood all the different functions: pci_write_config32 pci_conf1_write_config32 etc. I know that pci_write_config32 tries to find the correct pci_ops to use, pci_conf1_write_config32 tries to do it directly, but I don't know why one would work and not the other. V3 only has one pci bus ops struct defined. Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
