This message is opinions of PAO and newconfig people (me too): --- An ISA PCIC is undoubtedly an ISA device from the hardware's point of view. It has an ISA bus interface, and is connected to an ISA bus side of a PCI<->ISA bus bridge (south bridge). Why do you call it as "not an ISA device" ? As we repeatedly said, We are going to treat a PCI PCIC as a PCI device, and an ISA PCIC as an ISA device. This has several merits as below: - This is a natural abstraction which matches hardware connection topology. - We can apply UserConfig to an ISA PCIC. (PAO can use it.) - FreeBSD's current pcic code doesn't work with the machines which has both an ISA PCIC and a PCI PCIC. The notebooks which has this problem are populer in Japan. In our method, this problem goes away. Why do you ignore the hardware connection topology, and stick to "an PCIC is NOT an ISA device" ? What is the reason ? -- NAKAGAWA, Yoshihisa y-nakaga@nwsl.mesh.ad.jp nakagawa@jp.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
