What the BIOS does after failed attempts will be determined by how that BIOS is programmed. We can't answer that, because yours may be different than mine. However, I've not heard of a BIOS that does anything other than make you reboot after three failed attempts. Grub doesn't change anything on the drive if you fail, you can keep on trying. Though I can't recall if it, also, tells you that you've tried too many times, making you have to reboot to try again. > 2.

And theirs didn't have that line. Ordinarily, I'd then suggest to simply add the line. But I suspect that adding that line's out-of-date advice, since your file did have this written in the comments: > # Ctrl-Alt-Delete is handled by /etc/event.d/control-alt-delete So look at that file, and see if you can work it out. On my older than yours, Fedora 9, computer that I'm currently typing on, that file contains this: # control-alt-delete - emergency keypress handling # # This task is run whenever the Control-Alt-Delete key combination is # pressed. Usually used to shut down the machine. start on control-alt-delete exec /sbin/shutdown -r now "Control-Alt-Delete pressed" By the way, I'll drop a hint: It's wrong where it says that key sequence is usually used to shut down the machine, it's usually used to reboot. That's what CTRL-ALT-DEL does on every computer that I've ever played with, and that's what the "-r" option means with the shutdown command. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
