I don't see any calls to BIOS functions from protected-mode. My idea is that
the freeldr.sys will be loaded in memory by DOS calls and then DX set to
some reasonable value and at last jumped on the address where is freeldr.sys
loaded. To the FreeLdr it would look like it was loaded by any
bootsector.What's wrong with this?
