[NTVDM]
- Add dummy INT 18h (ROM Basic) and INT 19h (Bootstrap loader) interrupts. If INT 18h will never be implemented, INT 19h can be used one day...
- Add the standard bootstrap code snippets at F000:FFF0 and F000:E05B.
- For compatibility purposes, and nice info reporting via tools like Microsoft Diagnostics, or Symantec SysInfo, or whatever else..., register nice BIOS Copyright and Version strings. Also add a version string at the end of the BIOS.
- Fix our reported BIOS model.
- Add some temporary documentation (from Bochs BIOS) about the ROM BIOS compatibility entry-points that some apps may use (instead of passing through more documented & standard interfaces).
