RE: Setting up X

[Mike MacDonald <mmacdona at tsi dot gte dot com>]

Oh, I'm building this on NT..  I'm mainly afraid of making this NT specific
rather than the other way around.   Win9x should actually be able to address
the ram, and the io ports directly.

I know I've done direct screen writes in Win9x.

DX is a good way though to ensure compatability, and I'm pretty sure that
other than the initialization time there isn't a hit for speed.

I don't know how well getio will run under 98.

Since a driver isn't required to do the directx stuff, the getio stuff may
be an NT only thing..

Your choice.  You decide what is best.
However with DirectX we need to make sure we use DirectX 3.0, not a
higher version otherwise NT 4.0 will be a problem.
