The last time I booted my ibm-pc, I got an error code on
the screen that said '40FF'.  The machine then hung.  I 
attempted to isolate the problem by removing all extraneous
expansion boards.  When I had removed everything but the
video controller I got an error code that said '4090'.
Does anyone know what these error codes mean, and what I
can do to make my computer work again?
