This situation is covered under "amd64 and i386 notes" section of the FAQ: http://www.openbsd.org/faq/faq7.html#SerCon No Good Solution. If your goal is a serial install, turn off the BIOS console redirection, assuming you don't have a "Continue console redirection after POST" option, and set up a boot.conf file in your tftp server which will switch pxeboot over to serial console. Skip the 115200 baud stuff. That's silly... Your serial solution goes from being "when all else fails, I have serial console" to "Yet One More Thing Causing Problems". 9600 bps is reliable, runs long distances, works with almost any device and/or OS on the other end, and Just Works. 115200 is for either doing something via serial you probably shouldn't be, or showing off, "look what I can do!"
