Beeman" To: freebsd-questions@FreeBSD.org Subject: Redirecting console output to serial port to capture error message X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 05 Nov 2004 07:15:00 -0000 I have been trying to capture the error message that I receive when trying to boot any of the Release 5.3 beta or release candidate iso images on my DEC Personal Workstation 333i+. The system is an LX440 chipset based dual processor (2x PII 333MHz). I have been trying to redirect the error to the serial port and worked a while to get to where I learned that this incantation: #mkisofs -U -R -V fbsd_bootonly \ -no-emul-boot -b boot/cdboot -c boot_catalog \ -o /home/mbcd.iso /home/bootcd/cdrom after adding a /boot/loader.conf.local file containing console=comconsole to the contents of the bootonly.iso copied to /home/bootcd/cdrom would actually redirect this much of the output to the serial port: /boot/kernel/kernel text=0x4363cc data=0x7cc00+0x4fe20 syms=[0x4+0x5a690+0x4+0x6f5d8] but after that, the error message still pours out only on the video console, repeated endlessly, rolling by much too fast to make any sense of. What am I missing about redirecting the console output? I'm reading section 20.6.6.1 of the the "fine" manual, as saying that this should do the trick. Roger L. Beeman
