As soon as my DSL comes back up (when > you'll see this mail, likely) I'll update and try and see where we're at. All platforms, including ones without an ISA clock will deliver clock interrupts at the advertised frequency from PALcode. All we need is something to tick the scheduler during device probes - when the real clock attaches, we will calibrate things and install timecounters etc. -- Doug Rabson Mail: dfr@nlsystems.com Phone: +44 20 8348 6160 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
