The software Zebooka is referring to can be downloaded from
http://dednev.pisem.net/setup_gx10_dmctrl_1.1.exe
Password for installation: penta-club.ru
For furher information about use and installation see thread
"K10D Firmware 1.3 Debug Mode Unleashed! " on this forum. You will need these instructions as the keys have russian texts only (or something else incomprehensible)
I installed this software some 6 months ago. No problems, have found it very usefull.
