Sorry, no treat there. :) It all runs just fine on the same hardware if I pull hda, rejumper hdb to be hda, and reboot to FC2 from that drive. I've done that a couple of times today just to check. The mobo has 2 serial ports, and they are both allocated to external hardware stuffs. ttyS0 for monitoring my UPS, and ttyS1 for running all the X10 goodies. Mobo is a biostar, 2nd generation with good caps, about 3 years old now. -- Cheers, Gene -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
