Korg Poly800/EX800 Users

The ability to flash into your Poly either boot code or the software
itself should work as long as your Poly can get into FLASH mode.
If you want to get to version 2.65, you MUST have boot code version
1.98, 1.99 or 2.00.
If you try to run 2.65 on boot code that is below 1.98, it will NOT
work.
Upgrading the boot code requires sending the boot code to the synth in
FLASH mode and then swapping the boot rom with the flash rom next to
it.
If you don't swap the chips, then the boot software is NOT upgraded.
