The term descriptor and for that matter the Wx descriptors can be 
modified at the following offsets:

$30 = screen type
$31 = column start
$32 = row start
$33 = foreground color
$34 = background color
$35 = border color

You can use dEd and link directly to the descriptor module, modify the 
values, write it out to disk, and then verify the file (to calculate 
correct module CRC).  When you reboot the new changes will be in effect.
