- Remember that the Windows 3.1 drivers can make a real mode call down into
- the video BIOS (Int 10h) to set the appropriate display mode, etc. The
- Windows NT display drivers cannot do this (one reason is that this is not
- portable i.e. the BIOS code will not run on a MIPS machine. This may
- sound foolish, for a driver to be portable, but we have (and do) run
- add-in boards in some of the MIPS machines we use.) This has lead to the
- minor variations in the drivers that you see.
