Hi All,

Need some help with my blizzard PPC.

I have a A1200 Rev 1D mother board and a 200mhz PPC/ o4o card and when I power on I either get a black screen or sometimes a red screen.

The o4o does get quite warm (so I don't think it is dead but I could be wrong) and the machine can be rebooted (A, A, Ctrl) but no matter what I do (hold Esc, or both mouse buttons) I can not get anything on the screen besides black or some times red.

I have tried this with no ram mounted and no other devices attached with the same results above.

I do have a 235 watt AT power supply powering the whole thing (I tried another power supply just in case) and I have an extra 5Vdc wire going to the PPC fan connector and the fan powered separately.

Do I have a dead board? :-(

Yes apply the timing-fix if you haven't already. On a side note: all my power & power-on problems with PPC+BVision went away after installing a Mediator with Voodoo 3.

In the worth case,
take off the ram and press  ²  while booting.
If it's still problematic, send it to amigacenter.

OK, so I made a mistake in my last post...  If I do hold down the 2 key with or with out RAM installed the 1200 boots up...

So what does that mean???

Also, the silk screen on the mother board does say 1D, is that a 1D1???

Also if this is a 1D1 does the timing fix of removing the 2 SMT capacitors on the back still valid???

Any more help would be much appreciated guys, and I thank you for all the help so far!

hi . u didnt say if you just brought the blizzard ppc card.
if so when brought mine it brand new all those years ago.
it just didnt go with my orginal motherboard rev id 4
l thought brought a dud card.
so went got second hand 1200 and worked right away.
its been going ever since many years with out any problems.
just suggestion.
also go into the ppc boot menu and try setting up diffrently ie 70 ns memory no maprom etc . also disable the scsi . just ideas.
hope u work it out soon am sure u will. :-)

@AmigaMance

Thanks for the response, it makes me feel a bit better that its not a dead o4o.  I tried removing the hard drive and only power up with just the floppy, same thing, I also tried with no floppy or hard drive, same thing, also tried just hard drive, same thing, the "insert disk" screen never appears.

@actung_bab

I purchased this card almost a year ago, it worked with my old A1200 (I don't recall the revision on that board) but that A1200 died and never tried the card again until I received this A1200, been very busy travelling for work) and I just recently tried running with this card (I had a 1230 MKIV in this A1200 with no problems)
Problem is I can't get into the PPC boot menu or the Amiga boot menu, the machine never changes from a black screen unless I hold down the 2 button.  I have a fan blowing across the o4o but I will try installing a heat sink/fan combo.

@ -D-

Thanks for clarifying that, but I did find in another post on here that some one with an 1D1 motherboard did remove the caps on the back (E123C & E125C), once I find that post I will provide a link and ask the fellow if it did make a difference.

:EDIT:

OK looks like Painkiller removed the 2 caps on his 1D1 board
Here

just get another motherboard its that simple its never going to work with that one.
just some dont and thats all there is to it its the facts of life nothing wrong with the blizzard card or the 1200 mb just some borads dont like this blizzard ppc design.

l send you one my spare 1200 mbs if it help. but u shoulkd be able to buy one easy enough. when l had my problem same as yours the dealer that l brought the ppc card told me just this and sold me another 1200 real cheap. so not a problem.

Just an idea (and I must admit I'm not too familiar with the Blizz PPC cards), does you board have SCSI? I know some Apollo cards will search forever (black screen) for devices, unless SCSI is disabled.

Another thought, IMHO there's nothing wrong with trying 3.1 ROMs. E.g., I have an '030 card that only likes 3.0 ROMs... so as I see it, it's a cheap/easy thing to try.
