It's asking for a 32-bit accessible memory region - I'd have to go look up the encoding of the field to tell you how big it is. It also wants an interrupt. It's certainly not emulating a UART. > I'll go plunge around the Diamond Multimedia pages and see if I can find > any information. (Yeah, right). More useful than that would be to tell us what the part(s) on the card are. Diamond just use off-the-shelf parts in most of their designs; they're too small to do anything really custom. Then go hunting for the datasheets for the parts in question; that's where you'll find what you're after. -- \\ 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-hardware" in the body of the message
