You have to set up the serial console. ------------ A good answer on your average PC. (And perhaps even for this one :) However, the Intel L440gx+ motherboard I have (it came in a VA Linux rackmount) seems to have a separate CPU performing all kinds of monitoring tasks, watchdog, etc, so I was hoping this separate CPU was actually performing the serial console task. As I read it on page 64 of the manual (download from Intel), the second serial port is actually connected through a multiplexer to the Baseboard Management Controller (Dallas 82CH10) in my configuration. ftp://download.intel.com/support/motherboards/server/l440gx/254151-003.p df On page 36, the EMP 'always active mode' I selected suggests that console redirection remains active, and the OS can not see the port (or by extension take control of it). Which would seem to leaves the graphics mode issue. FreeBSD should be oblivious to the fact that this re-direction is even going on, but the kernel seems to do /something/ that impacts the built-in serial console. I guess the idea is to not have to use the FreeBSD software serial console, but use the hardware serial console out that comes with the motherboard. [FYI, there is a FreeBSD project to access the IMPI functions of these motherboards. <http://people.freebsd.org/~dwhite/ipmi/>, but it seems to address a slightly different question.
