mentions a patch to disable the boot manager beep, and also discusses having it optional. I don't have enough asm-fu to make that option happen, but I can tell you, that on laptops, that beep is really annoying, and amazingly loud. Is this just waiting for an able minded person to code up the options and submit?
I don't like the beep either, so I usually patch my systems manually to include something very similar:

Since this is asm, and it runs very very early in the boot process, we don't have the luxury of making this tunable in `/boot/loader.conf', but there's nothing wrong with making it tunable through an option in our modern `/etc/src.conf' option system. We could use something like the following:
WITHOUT_BOOTEASY_BEEP= yes
and then we can add the necessary Makefile-foo in `/usr/src/sys/boot' to turn this to a preprocessor #define.
Does something like the following sound reasonable (I haven't had a chance to run this through a build-test, so use with care). The default behavior should be to *include* a beep, but it can be turned off by setting WITHOUT_BOOTEASY_BEEP in `/etc/src.conf'.
