Boot1 setup GDT that resides locally and must be overriden by the Kernel. The ESP is set at 0x27FFF location. Stack now resides is the Data segment not on a seperate segment - GCC does not support SS =/= DS.

* GDT resides at static 0x800 location with space for 512 entries. Local copy is copied to that location. * Separate Stack segment. 128KB of stack starting from 0x27FFF to 0x08000.
