Larry; I meant to get back to you on this earlier, but your previous message is still buried. The short answer is that you can't "block" ISA interupts, so the problem you're seeing has to be related to how you're talking to the card. The only confirmation of interrupt delivery that the card will ever get has to come from your code. -- \\ 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-hackers" in the body of the message
