You need to know whether you have a TTL monochrome monitor with
Hercules compatibility, or an RS-170 (aka NTSC)  monochrome monitor.

If your system "thinks" that you have a CGA monitor by virtue of the
fact that this board is emulating it, then no problem, right?

>I think cga has 2 colors right?
No, a CGA monitor has 16 colors.

This question throws me off because above you state that you are doing
CGA emulation in which case I would think that you should already be
telling your BIOS that you have a color monitor.

There are a bunch of different CGA emulators for Hercules type
monitors at wuarchive.wustl.edu in the /mirrors/msdos/screen
directory.

By the way, I have a similar situation in reverse.  I have a TTL type
monitor that I am running off of an ATI Graphics Solution card.  This
card can run a CGA monitor directly and only in CGA mode.  It can
also run a TTL monitor in Hercules mode, IBM Monochrome Text mode or
in CGA emulation mode.  You can either configure with switches or in
software that is provided with the board.  The board comes with
configuration software as well as several software specific drivers
(i.e Lotus, Wordstar and Framework).  Even though I just got the
board six months ago, its an older product ( date of manual= Sept. 89).

I am posting instead to see if others can add to this.
