80386 BIOS have a feature called "shadow ram".
On some BIOSes, you can disable the "shadow ram" and free up the memory
space between 640k and 1Mb. Some BIOSes will still reserve this space
even if you disabled the "shadow ram". But, by disabling the "shadow ram",
you will cause the computer to operate slower due the the "far" reference
for ever BIOS interrupt call.
