Powering a BPPC 68060?

@Sinan

I'm not 100% sure at this moment as I'm not in front of my Amiga, but I have a bad feeling that it is an ID4 board.... do you think that would be causing my problem?

Does anyone know of a fix?

The board itself doesn't crash after I pull out the secondary power (as ive described above) - it just doesn't boot when the power is in - it starts, then stops (so I'm presuming when it stops it crashes?)

If it is a crash, could that be down to a timing issue do you think?

Any help/advice would be greatly appreciated!!

@Sinan

Just had an after thought, my previous Blizzard Accelerator card with an 040 chip (instead of an 060) chip worked just fine?? Could it be to do with the card itself then??

@badgerme

060.library ?

@Daedalus
Thanks for the info.

@badgerme
Install the 68060-libraries found here http://phase5.a1k.org/
the first two lha-packages are what you need. You can read about the library-naming issue here: http://xoomer.virgilio.it/dario.manzoni2/1260software.html#mess

Also have you done the A1200 mobo timing-fix?

Thanks for the advice - I've got a feeling I've got the ID4 revision (not sure until I open her up) but to be honest I'm wondering if this is down to a timing issue? The reason I ask is because

a) I didn't have a problem with my previous Blizzard PPC with an 040 chip running at 40mhz
b) The card boots and runs fine without any crashing - once It's fired up (after I do the power in, power out trick I've already described)

As you can imagine, I don't like opening her up just in case she breaks, so I'd like to get as much knowledge together on the subject prior to diagnosing and repairing the power fault.

I am wondering if plugging the fan connector on the BPPC board straight on to the ATX Psu (5v supply) would help at all, and not plug the ATX Psu on to the mainboard.

Does the ATX PSU need to be plugged on the motherboard (at the floppy connector point) for everything to work properly?)

Cheers tho guys for all your recent advice - its been really helpful

@badgerme
You could try the power trick to BPPC fan connector, i used it when i had a BVision and it made my system more stable. Make sure you connect it the right way (red wire towards the ppc-heatsink, black on the edge side of board)

@bamiga2002

What was the 'trick' intended for? Is it safe to attach 5v straight from the ATX PSU on to the blizzard card? Does the Blizzard card indeed draw power from the fan connector??

Seems a bit odd to me...

Presumably, so longs the + and - for the 5v are the right way around, then it shouldn't do any harm?

@badgerme
I had an AT-PSU at the time and i connected the 5V directly to the BPPC fan connector. Surely there's no difference with an ATX PSU if its 5V line's connected to the same connector. Also you can connect your spare floppy connector from PSU to the A1200 motherboard floppy connector to feed the BPPC more. Read here:

@badgerme
I also encourage you to flash your BPPC with this flash-update http://powerup.amigaworld.de/download.php?id=3 if you haven't done it yet.

adding extra power at the fan connector does help a little and works fine but i DO NOT recommend it.

extra power should be at the floppy connector.

but you say when you feed extra power at the motherboard floppy socket you system does not boot you must also plug-in the floppy drive in-order to boot into workbench..

its also best to do a flashupdate update when power problem is fixed.
