You can answer me tomorrow if you like but here is an update: I removed the cdrom and the problem remains. I got the usb ports to work as well by updating the bios and fiddling with some settings. It is truly a mystery why this 300 GB drive cannot talk to FreeBSD. Again, it is detected fine by the bios; it passes dos level diagnostics; it is on the same ide cable (as slave) as the 200 GB drive that is identical to it save for an extra 100 GB. My next step is to boot with knoppix to see how it behaves. -- Peter __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
