>> Can you add/more I/O wait states to the cpu

Flipping the I/O wait dip switch (position 2 of SW1) didn't change anything.

Just to be sure, I spent a lot of time going back to be positive that I had a clean copy of "MYIDE". The only change is the port numbers for the IDE card. I believe that they were 30h, 31h, etc. in the posted code. I had to change them to 50h, 51h, etc. because 30h conflicted with another card in the system. That's the only change. I've attached a log of the session in which I ran this "clean" copy of "MYIDE", and my home grown CF/IDE utility. I added a dummy write to the initialization routine in my utility. You can look at the results. "MYIDE" reads all 2's in the first sector, but my utility reads 1's (which is correct). I must also add that in both cases, the hex display on the card shows 00 00 01.

I'm going to move on. I'm not happy with this kludge, but I've wasted enough time on it. Maybe somebody way smarter than me can figure it out???

Thanks for looking at this.
