Hello all
After a succesfull biosupgrade to v113 my x98 pro was dead after 2 days of reading on this forum and trying all kinds of different start combinations i opened the pro and desoldered the 25lq64cv.
I used my tl866 to flash the chip, it is set to 1.8 v by the programmer, programmed it with v301 and soldered .
After that the pro was running with windows v1703 and mirek v6.
Thanks for the usefull information on this site
