If you don't have "PnP OS" set, and the card doesn't get resources assigned, this means that there's a resource conflict that prevents the card from being configured. > how can i solve this problem?? one way out is to have the driver assign > physical addresses to map the pci space. however for that i need the > physical map...what data structure holds that?? Either turn "PnP OS" off, or fix the card/system. The driver can't do resource assignment like you're talking about. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
