You will have to poke around in the SRM leavings to do that. You might be able to prod the Linux code for some help.

Once you have 'ppc' ported, you can use 'ppi' to do that sort of thing. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
