It used the support in Isolinux and Grub to cause those beeps,
depending on whether you boot via BIOS or UEFI. Grub is more likely to
be helpful to you on an installed system. In the installer's version
of grub.cfg are the following commands which make the beep noises.
play 960 440 1 0 4 440 1
You could use something similar. Even easier, there's already support
in the normal Debian grub packages for making a beep at startup. At
the end of /etc/default/grub:
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
