BlizzardPPC - flash dead! (any help?)

[tomekm]

I`ve got a Blizzy which did me following from time to time: Whe I poweron the ami, it ca. once a week started without recognizing Blizzard. Amiga seen only 040 and no fast, and no autoconfig entry. But after did Flash-update (which took about 10 minutes), and reboot, everything was working fine (for next few days...). But suddently it crashed, but worse happened: I am getting red screen on boot, and machine resets repetadely. I can not even get to bootmenu.

Does anyoune have any solution for it? It would be good if I could just bootup machine, but it`s not possible. The flash chip (AMD 29f040 - revenge or what?) is soldered directly to Blizzard so it is not easy to replace it... Please help!

ok:

-my amiga works without blizzy. (works even with Apollo1240)
-I`ve already cleaned all connectors i`ve found
-I have no BVision
-I tried to boot with "2" pressed, but did not succeeded (blank screen), but I`ll try again.
-thanks to StormLord.
-if everything fails, I`ll try to contact ARC France, as I already did with Elbox (they said they may try, but no promises).
-i`ll put a small radiator onto flash ROM


StormLord: to verify: if i disable Blizzy ROM ("2"), the 040 propably will stay on (i think it`s connected directly to mobo registers), so no 020 will be used for flashing, but I know, the flashing process without FastRAM is reaaaaaaaaly slow...

On my blizzy it stayed on when there was my previous problem (flash corrupted and no blizzy found in system, but system worked...). there was only 040 visible from all the blizzard.


I`ll thank you when I manage to repair Blizzy myself...

(if ARC France repair, I`ll thank you too;)

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.
