phase 5 blizzard iv 1230 64 mb not booting up

[digiflip]

I thought it was power supply problem, but i think can safely rule that out tried 3 different power supplys atx type (using ian steadmens atx adapter)and now just bought a brand new antec earthwatts 430 watts, just in case my old power supplys weren't pumping out enough 12volts but still same problem won't boot when connect blizzard to my amiga 1200 power tower.

I have some 4 meg simms tried managed to boot to workbench but then crashed. When rebooted software error.

I got ibm 64 mb simm (FRU 42L0255) with it. Using a1200 motherboard revision id1.

I plugged in power monitor to my ac outlet to see if the blizzard is drawing any power it seems to draw 4 watts surely it uses more than that?

looking for any suggestions?

its never worked for me but the person who gave me the blizzard said he tested it on his amiga 1200 before he sent it me. I have at the moment disconnected my ide splitter to see if will boot to normal floppy boot up and early startup screen with 2 mouse buttons pressed.

I am double checking the connections to my ian stedman atx adapter
 ie +5v -12V + 12V and ground connections.

ok reinstalling os 3.9 to my spare 40gb laptop ide hard drive and see if the card will boot up with that.

nope just blank screen when insert blizzard card tired number 2 thing still no boot. When load hdd now software error since not enough memory to load os 3.9 rom.

thanks for the advice, i think maybe have bad memory since I did manage to get to early startup menu once or twice yesterday with 4meg memory. Also once manged to boot workbench with it but then screen kinda was greeny and then it froze.

I might try getting another simm. or just saveup and buy aca1231 from versali.de

Just a shot in the dark here, but does your A1200 have the "timing fixes" ?

Did you have an accelerator before ? Did it work well ?

Is your A1200 a Commodore A1200 or Amiga 1200 from Amiga Technologies ?

You could also check that the edge connectors of both your A1200 & Blizzard are clean. If you have a PCC cleaner try cleaning the edge connectors.

The motherboard is commodore revision 1d1, I think the timing fixes were done by commodore from what I read about this revision on the net.

checked soldering near crystal has mine is not seated is soldered on, two of the solder joins look bad might try re-soldering those two legs. Has bad solder joints are bad lol.

[digiflip]

still the same, so ordered crystal 50 mhz and socket from amigakit.

[digiflip]

maybe

bit the bullet bought aca1231 but will try fiiting a new crystal to get this working, if dont get working anyone know what sort of price I can get for untested/maybe repairable blizzard iv?

[digiflip]

does any1 think i should get this board tested on another amiga 1200 before attempting to solder on new crystal?

tested with 4 mb simm no screen, 64mb simm no screen, 16 mb simm no screen

so I am thinking crystal, motherboard timing/expansion socket or card is dead?

in my attempt to solder on another crystal, i gaveup and just resoldered the crystal allready installed, now working.

now attempting to install os 3.9.

happy days.
