Hi guys! Some of the people of the kernel mailing list told me to build up the disable pcspeaker support with sysctl. It is done and works perfectly! Will you apply the patch to kernel 2.4.5 ? If so, can anybody or can I change the config.in files ? Regards, Nico ps-1: My mail route is currently broken. please resend emails in the next days, whether some returned! I am working on the line problem! p.s.: overview: 1. Changed drivers/char/vt.c (diff attached) 2. Changed arch/{i386,alpha,ppc,arm,mips}/config.in : if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then bool ' Disable the PC-Speaker' CONFIG_DISABLE_PC_SPEAKER fi (should be the last item of the 'General Setup' Menu, I don't attach diffs for all those different config.in files) 3. support for sysctl: changes in kernel/{sys.c,sysctl.c} and include/linux/ sysctl.h (diffs attached) 4. wrote text for Configure.help: (attached)
