    I have a nameless clone 286 motherboard that is able to assign the memory
above the 640k as extended.  The only problem is that when I put my 4Meg EMS
board in, this memory is lost.  Instead of reporting 5 Meg of memory, my system
reports 4+640k (whatever that turns out to be.)

    Anyway, this was off the topic, but I wanted to let you know that other 
generic boards will use the 384 as extended.
