I should have sent this a while back but forgot. Our vendor had a fellow spend a couple of days looking at the problem. Here's what we are using. modprobe w83781d init=0 ignore_range=0,0x00,0x28,0,0x2a,0x7f modprobe i2c-piix4 he gave a pretty good walk thru of how he debugged it. It's in my mailbox at home and I'm having some network problems at the momemt. If you are interested I'll send it along later to add to this ticket. --john -- John Lash jkl at sarvega.com 630-734-5925 Sarvega Inc. 745 McClintock, Suite 230 Burr Ridge, IL 60527
