This is interesting - it was recently pointed out to me at work that the
Radius DirectColor 24 board would not allow A/UX v1.1 to boot.  I verified
the problem and the ROM on the DirectColor board was modified to allow the
system to boot.  Therefore, there is now a ROM (version 1.1) for the Radius
DirectColor board that will allow it to work under A/UX 1.1.

When we first released the DirectColor board, it was believed that it had
been checked with A/UX, though at the time we only had 1.1 beta 3 of A/UX.
I wonder if something happened between beta 3 and the release version that
made 24-bit video boards not work (?).  Otherwise, it just wasn't really
checked as we had thought.

I'm not certain if our fix for 1.1 will also solve any potential problems
with 1.1.1, since we haven't gotten 1.1.1 yet.  Any comments from someone
with 1.1.1 and a DirectColor board would be appreciated.
