Hi, I have to come back to this problem. When I boot over the serial console, input works all fine until I come to the loader menu. There, input from the serial console is just ignored, I can not interrupt the autoboot and e.g. choose a different kernel. I have partitioned with GPT and installed /boot/pmbr into the MBR and /boot/gptboot into the first partition of type freebsd-boot. The keyboard works in the BIOS, and in gptboot I think, where I can interrupt the boot by pressing a key, and a list like this shows: FreeBSD/i386 boot Default: 0:ad(0p2)/boot/loader boot: Then, in the loader menu the input is dead, when the kernel boots and also afterwards it works again fine. When I use GRUB to start the loader the keyboard also works. Any ideas on what the problem could be or how to track this down?
