Just need to init to 80 x 25 color text.  Load an 8x16 font and write
attribute/char data at 0xB8000 in the standard fashion. That's it.

I can get a register dump from the board with the mobo and PC-BIOS, assuming
in alpha mode it has legacy CRTC, Sequencer, Attribute, Graphics, etc in the
standard locations.  But I need to know the extended register settings to
enable access to these from power on.  And any extended DCLK register
locations/settings required.

Any help you can give would be appreciated.  I don't have a problem with an
NDA unless is prevents publishing the source code.
