One or two like every new world Macintosh. =) In fact quite a lot of PowerPC boards use OpenPIC as it's specified in the CHRP spec, which IBM and Apple follow for the most part. I know that Motorola's MPC10x host-pci bridge chipsets also have an OpenPIC-compatible PIC in them. I also wouldn't be surprised if the Mai Logic chipset used on the Teron CX motherboards has one as well. -- Benno Rice <benno@FreeBSD.org> [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQA+QExXXjRwWofFmQkRAi+uAJ9u6KMbfwzbkwtk0Cv+yudcHkcmKQCaA21a FZXMV2FvF+lUl/umadNQBdU= =ZZnn -----END PGP SIGNATURE-----help
