     A long time ago I purchased one of the early 286 AT clones.  In the 
intervening time I installed a high density 3.5" drive and at that time
I had to upgrade the BIOS.  When I bought the BIOS (Phoenix ver 3.07)
the manufacturer told me that the new BIOS supports the enhanced keyboard
if I ever wanted to get one.

     Now my old keyboard died and I went out and purchased a new one.  The
new one is an enhanced keyboard (has 12 function keys and separate inverted
T cursor keys).  The new keyboard seems to work fine in everything I do
except when I run MS Windows 3.0 where I get lots of keyboard errors.  For
example in Ami Pro, my wordprocessor, the inverted T cursor keys give me 
numbers on the screen instead of moving the cursor and the extra keys 
labeled HOME, END, PgUp, PgDn, Ins, Del don't work.  However all those keys
work just fine when I used the keypad.  Also sometimes no matter what I do
all I get are shifted keys.  These problems didn't exist with the old keyboard.

     I tried a diagnostic program which shows the keyboard working just fine.
I can't tell if the keyboard is the problem or Windows.  I also wonder if
changing the BIOS isn't sufficient to upgrade the old AT keyboard to an 
enhanced keyboard.  What about the keyboard decoder chip?  Would that need
to be upgraded also?  If so, can anyone suggest where I can buy a new
keyboard decoder chip?  Luckily mine is socketed.  Would it help if I 
reinstalled Windows?  Does Windows have a line in one of its .ini files
specifying type of keyboard?

Thanks for your help.
