     89 *
     90 * The real mode segment numbers for BS16TEXT, BS16DATA and BS16SYSTEM are
     91 * present in the GDT, this allows the 16-bit C/C++ and assembly code to
     92 * continue using the real mode segment values in ring-0 protected mode.
     93 *
     94 * The three segments have fixed locations:
     95 * | segment     | flat address | real mode segment |
     96 * | ----------- | ------------ | ----------------- |
     97 * | BS3TEXT16   |   0x00010000 |             1000h |
     98 * | BS3SYSTEM16 |   0x00020000 |             2000h |

     100 *
     101 * This means that we've got a lot of GDT space to play around with.
