How can I get rid of this kernel option? Is your /etc/grub.conf still a link to /boot/grub/grub.conf ? (or a separate /etc/ file was created by some script/editor ... which seems to be common error ...) I assume that you've edited grub.conf yourself since (at least 3.1-3 version) SL_enable_serialconsole does not remove grub.conf entries upon de-installation ... Cheers Jarek PS: console=tty0 shall not cause any problems for your serial-connected UPS (this is the default console: first screen on first adapter), but please also check /etc/inittab entries for occurences of ttyS0 there .. __ ------------------------------------------------------- _ Jaroslaw_Polok ___________________ CERN - IT/FIO/LA _ _ http://home.cern.ch/~jpolok ___ tel_+41_22_767_1834 _ _____________________________________ +41_78_792_0795 _
