:>     Similar problems have been posted to the FreeBSD groups.  The
:>     concensus seems to be that a lot of BIOSes have severely broken USB
:>     legacy keyboard support and that you are better off either using 
:>     a normal PS/2 keyboard, a USB-to-PS2 converter on your keyboard
:>     cable, or going native USB all the way.

:Thanks Matt.  It's odd though that linux deals with whatever this problem is
:seemingly well as well as Windows.
:The problem this presents for me only occurs when I need to switch what OS 
:I am booting into as I need to either plug in a PS/2 keyboard or switch
:legacy support on to be able to navigate GRUB.
:I will check if there are any BIOS updates for my hardware before diving much
:deeper all the same.  I've seen hardware work with AGP in Windows and the 
:Linux drivers couldn't deal with the problem on certain HP systems as well so
:I know this can be tricky :).
:I'll keep the list updated if fix is in the BIOS.

    Another thing you could do is search the FreeBSD archives to see if 
    there are any USB legacy keyboard issues that have been fixed in 5.x.
    If so we can backport them.  But I do not recall any from my read of
    the list.
