An MSI motherboard did the same thing, only with a USB mouse. The BIOS defaulted to legacy emulation. The mouse would be briefly enabled during boot, then disabled as FreeBSD started. I found a message explaining it, disabled BIOS emulation, had no further problems, and... didn't investigate further. Now I can't find the exact post, but did find a thread that is similar: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1607862+0+archive/2008/freebsd-questions/20080224.freebsd-questions -Warren Block * Rapid City, South Dakota USA
