Allegro only uses nearptrs when it is using one of the SciTech VBE/AF
drivers, which isn't a problem because those don't work under NT in
any case. The VGA and VESA modes, and VBE/AF when using the FreeBE/AF
drivers, work entirely with nearptrs.

To the original poster: I don't have access NT myself, but I have heard 
that Allegro does work under it when using the basic 320x200 VGA mode. 
Your mileage may vary, though. The mouse stuff in particular is very
likely not to work or even to lock up your machine, so you may well
not be able to use that at all.
