Folks, I have been getting a message about some modules missing and one of those is what I referenced in the subject line. I looked it up in the devices.txt file in the kernel tree and found 188 = /dev/smbusbios and curious exactly what its purpose might be. I dont' think it has to do with a usb port either.<grin> I'm not so sure I've seen a smbus bios before. Any thoughts appreciated. tia Scott
