Re: [Devil-Linux-discuss] Beep in serial mode

[mailing d. <mai...@gm...>]

1) booted a computer on dl1.4rc6 with standard CD:
# cat /proc/cmdline
initrd=/boot/initrd.gz vga=773 BOOT_IMAGE=/bootvmlinuz

2) enabled serial in inittab (uncommented)
S0:2345:respawn:/sbin/agetty ...

3) save-config

4) booted with new configuration
# cat /proc/cmdline
initrd=/boot/initrd.gz vga=773 BOOT_IMAGE=/bootvmlinuz

It looks the same;)
