ok, i did following: i tried to boot with "2" pressed and it succeeded. I had blizard dissabled and the machine displayed boot menu. i booted w/o startup and started flashupdate. Then it said: "No BlizzardPPC found". I tried to supply with 160mhz and/or FORCE params, did not help. What now?
BTW: I hacked the keyboard by soldering two cables directly to mobo keyboard MPU and connecting CDTV black KB

so it works like normal KB (without reset, ofcourse).
EDIT: I supply reset from Tower button to TP on motherboard.
