I'm a little confused by this.  SeaBIOS seems to assume that it only has 
to deal with the 0xf0000 .. 0x100000 space as the bios which is 
certainly true (i don't think there's anything special about the 0xe0000 
.. 0xf0000 region).

I'm not sure why we load the 128K worth of bios instead of just loading 64K.
