Right now, I am just commenting them out, now I know what people mean when they say they are running a trimmed/clean kernel. I did see one potential issue... # USB support device uhci # UHCI PCI->USB interface device ohci # OHCI PCI->USB interface device ehci # EHCI PCI->USB interface (USB 2.0) device usb # USB Bus (required) I see all of these with nodevice lines in the PAE file. Although I have USB ports, I don't use them, but I was concerned by the 'required' on the last one, is it OK to remove? Also, would I then need to disable USB in the BIOS to avoid errors? -- Robert
