I believe I can confirm this behavior. I'm experiencing lots of troubles with tftp, but I'm running with a box without bios (thus without a proper timer source (no interrupts)). I've now made sure the box is alone on its subnet and stuff _seems_ to be better. /Anders _______________________________________________ Bug-grub mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/bug-grub
