I've had this program for awhile and decided to try it out last night
after being reminded of it by this thread of discussion.
I followed the docs to the tee, but....   she no worky for me!
If I runback the program, I get no indication from patch2090 that it's done
anything. No errors NOR activation info to the screen.  I go into DpaintIII
with hi-res 16 color, and loads and saves still take FOREVER.
Has anyone actually had this work?  Did Dpaint load and save (alot) quicker
than without it?  If I just run patch2090 then it complains that it couldn't
find any devices and that I should re-read the docs.
Could it be that I have SetCPU running with the fastrom option and the 2090a
has the 'CardROM' option going?
Here's the hardware:
  Rev 4.5 2000
  2090A
  2620
  ProRam
  SuperAgnus
  etc. 
I added the MaxTransfer line to both my FFS partitions and have the
startup-sequence runback patch2090 right after the second partition has
been mounted, no difference in operation though. :^(
