I'm not having any luck getting my 115200 baud serial console back.
The machine was upgraded from 5.4-STABLE to 6.1-PRE last week, and
again over the weekend. I did the following:
make buildworld and buildkernel with BOOT_COMCONSOLE_SPEED=115200 in /
etc/make.conf, options CONSPEED=115200 in the kernel config.
make installkernel, reboot, yada yada yada, installworld,.. then
boot0cfg -B aacd0 to update the boot blocks.
Now, at this point I expected to have a 115200 console on the next
boot. Nope. Got 9600 baud again.
The other side-effect is now I get this stupid "Boot F1 for DOS and
F2 for FreeBSD" menu which defaults to DOS (which is the Dell utility
partition). How do I get back to the original boot style where it
just boots freebsd without any menu?
So I updated my /boot.config to read:
now on boot, the boot0 drops to the prompt and makes me type in "/
boot/loader" to continue the process. It is as if it forgot what
file to load, and ignores the -S option anyhow, because I still end
up with a 9600 baud console.
I ran out of time to try setting the speed in /boot/loader.conf but
I'm not expecting any miracles.
