Thanks. I have a test I want to run tonight after work, provided MC1 doesn't beat me to it. I am curious to see about the checksum calculation. I solved the D1 16 bit checksum mystery and I am curious to see it the DX uses teh same calculation. This will solve all the flashing to see what the checksum SHOULD be issue. Plus if I get it figured out, I can make boot logos for the DX without a device to test flash them.
