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.

... 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 But I suspect that adding that line's out-of-date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
# 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
[tim at localhost ~]$ uname -r
