Things seem to be different in the 4.0 kernel configuration steps (I stumbled upon "options PNPBIOS" which is hidden somewhere in the documentation); boot -v reports some PnP scanning activity, and pnpinfo(8) correctly reports my sound card (as well as my 'winmodem' which I dont use). My kernel CONFIG file says "device pcm0" since i'm hoping to use pcm. After much hacking I have realized the following: if i do a boot -c and then do 'visual' and then expand the nodes, it asks me if I want to save the changes, (no matter if i say 'yes' or no) it *correctly* identifies and runs my sound card. I tried it out. There also seems to be a difference in the way the PnP stuff is being scanned, since normally there are about 6 lines of "Pnp device failed to report resource data", whereas if i do the boot -c thing it only has that line twice. This seems to be a stupid bug to do with the bootstrapper or something; I'd rather not try to involve myself in that stuff. >How-To-Repeat: Install a Crystal card. boot -c, 'visual', expand some of the nodes, quit at booting it will show your crystal card. otherwise it wont show your card. >Fix: I dont know. I think the code will have to be changed. :( >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
