Hi, The Linux kernel seems to depend on the BIOS for getting the PCI related information on i386(on 2.6 however it looks like this can be overriden by setting the config option CONFIG_PCI_DIRECT) My question is does Linux use the same memory/IO address as given by BIOS to the PCI devices? If it uses the same address as given by the BIOS, what range do this addresses lie? I am not very knowledagble about the BIOS but my understanding is that it works in the real mode!
