Re: Resetting bootloader on a CF
It occurs to me that there may be a couple of other wrinkles. There are kernel boot parameters that tell which kind of console to use, and there are switches you can twiddle in /boot/loader.conf, notably #console="vidconsole" # A comma separated list of console(s) console (``vidconsole'') ``comconsole'' selects serial console, ``vidconsole'' selects the video console, and ``nullconsole'' selects a mute console (useful for sys- tems with neither a video console nor a serial port). Also make sure that /etc/ttys launches a getty process for whatever console you are using. I.e., make sure it doesn't look like this one (mine) - make sure that at least ttyv0 is on. console noneunknown off secure # ttyv0 "/usr/libexec/getty Pc" cons25 off secure # Virtual terminals ttyv1 "/usr/libexec/getty Pc" cons25 off secure ttyv2 "/usr/libexec/getty Pc" cons25 off secure ttyv3 "/usr/libexec/getty Pc" cons25 off secure ttyv4 "/usr/libexec/getty Pc" cons25 off secure ttyv5 "/usr/libexec/getty Pc" cons25 off secure ttyv6 "/usr/libexec/getty Pc" cons25 off secure ttyv7 "/usr/libexec/getty Pc" cons25 off secure ttyv8 "/usr/local/bin/xdm -nodaemon" xterm off secure # Serial terminals # The 'dialup' keyword identifies dialin lines to login, fingerd etc. ttyd0 "/usr/libexec/getty std.9600" dialup on secure On Thu, Sep 1, 2011 at 12:59 AM, Polytropon wrote: > On Wed, 31 Aug 2011 23:47:22 +0200, bsd wrote: >> Part of the solution seems to be : >> >> 1.

You can use sysinstall for that: Configure, select the CF card to work on, don't chance anything with the slices in the fdisk editor, just make sure the slice is marked active, and in the next step, select the default MBR to be written. The command line way should be: # fdisk -BI /dev/da0 # fdisk -B -b /boot/mbr /dev/da0 (Assumption: /dev/da0 is the CF card.) Note that the first step will re-initialize the card. If you don't want to build it from scratch, i. e. _only_ modify the MBR, the second command should do it. See "man fdisk" for details on the fdisk commands. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Resetting bootloader on a CF
Hi, I am trying to reset the bootloader of a pfSense nanoBSD CF card. I need the boot loader to be reset because > The embedded image set the bootloader to use a serial console. That isn't > necessary with the box I am trying to use (the BIOS does console redirection > to the serial port for you) and causes the boot to hang. Part of the solution seems to be : 1. Mount the CF on a FBSD 2. Initialize the bootloader with : # fdisk -B /dev/ 3. This is where I need you help… How can I re-install a boot loader ? Should I use the command : # fdisk -B -b /boot/boot0 device Any other suggestion, guidance will be welcome. Thanks for your support. P.S. I'll check your answer in 10+ hours as I am already tired and It is 11.45 pm in Paris where I leave. ;-) - thanks for your understanding. –– -> Grégory Bernard Director <- ---> www.osnet.eu <--- --> Your provider of OpenSource appliances <-- –– OSnetOSnetOSnetOSnetOSnetOSnetOSnetOSnetOSnetO ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
