How to bypass loader.conf at boot
Hi all, I edited the /boot/loader.conf to add values for kern.maxdsiz and kern.dfldsiz. Unfortunately my server can not boot after that (the values are too big). How can I bypass the loader.conf parameters at boot? Or how I can change these values interactively? The server is located in a data center and I can access to it through supporter. Please advice. Thanks all for helping. PS. Please CC me because I'm not in this list. - With best regards, |The Power to Serve Nguyen Tam Chinh| http://www.FreeBSD.org Loc: sp.cs.msu.su | ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

He should boot with it and choose the Fixit option, and select the live filesystem on CD. After that, he will be dropped into a shell and the following steps will work: fsck -y /dev/da0s1a (change to the correct slice name!!) Once that is complete: mount /dev/da0s1a /mnt vi /mnt/boot/loader.conf save changes Exit the Fixit mode and reboot, removing the CD, and voila! -Wash http://www.netmeister.org/news/learn2quote.html DISCLAIMER: See http://www.wananchi.com/bms/terms.php -- +==+ |\ _,,,---,,_ | Odhiambo Washington[EMAIL PROTECTED] Zzz /,`.-'`'-. ;-;;,_ | Wananchi Online Ltd. www.wananchi.com |,4- ) )-,_. ,\ ( `'-'| Tel: +254 20 313985-9 +254 20 313922 '---''(_/--' `-'\_) | GSM: +254 722 743223 +254 733 744121 +==+ Nothing is more admirable than the fortitude with which millionaires tolerate the disadvantages of their wealth. -- Nero Wolfe ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks all for helping. Choose boot menu option 6: Escape to loader prompt Then you can set/unset anything. Use show to see the current values, set to set some parameter, load/unload to load or unload kernel or modules - see help for more.

When he will be done, he just need to unset those variables with the following command -- unset kern.maxdsiz; and unset kern.dfldsiz. After that, he will just have to type 'boot' and that's all. I hope that this will work for him ;-) Anyway, try to read through loader(8) manual page. Get the guy at the data centre to get a 5.x or 6.x installation CD. He should boot with it and choose the Fixit option, and select the live filesystem on CD.
