Hi Larry,
I have had the best luck with changing the Heads/Sector/Cylinders for
the card. I have tried to explain this here:
http://ted.openavr.org/Lenny-on-ts7390/
In your case above, I would try setting the geometry to this:
H = 4
S = 16
C = 2021654528 / (4 * 16 * 512) = 61696
After that, you can set up your partitions nearly the same as in the above link.
Hope that helps.
