Hello! As I read that Alan and Linus are more than busy, I just retry sending the patch to the list. The patch allows you to switch off the builtin pc speaker with sysctl options. No program will then be able to beep under Linux, nor under X neither in the console. Normally the speaker keeps enabled, unless you echo 0 > /proc/sys/kernel/pcspeaker With all values != 0 it is turned on (documented is 1). The support is included for i386, ia64, alpha, mips and mips64. It is tested under i386 with several kernels / machines. No problem occurs. The code should not make any problems on the other processors, but I would be nice if I could get feedback from people using this on alpha,... I (and maybe others ?) would be happy if someone applies the patch to 2.4.6. Thank you, Nico P.S.: I also attached an init script. This is from the clinux distrubtion and has to be changed to run without /etc/sys/combined and /etc/sys/boot/kernelsettings. If somebody is interested, I can send him/her the /etc/sys/ files.
