Re: My PC has 640Kb worth of chips but all the programs claim I have only
636Kb.
Some PCs make use of an Extended BIOS area at the top of regular memory. For
example, HP Vectra PCs using an HP-HIL mouse will load a 4K ExBIOS at the
top of memory for the HIL stuff.
Usually, PCs which make use of the ExBIOS will have some kind of option to
their SETUP program or the like to disable the use of ExBIOS at the cost of
loss of some functionality. In the HP VECTRA case, the ExBIOS can be turned
of on all modern VECTRAs (i.e. any except the ones that just say VECTRA and
don't have a model name like ES/12 or the like) by invoking the SETUP
command with a single argument, "YADA". (Why? I don't know!) This will
disable the ExBIOS, at the cost of disabling the HIL mouse. Not a bad idea,
actually; you can get much more ergonomic mice and the like for serial or
bus connection.
