Hey guys,

Well one of the worse thing has happened! I sold my BPPC card and the guy I sold the board to is having problems with his system being tempormental booting with the PPC card installed. I dont know much about his system and I'm not techincally minded on hardware! but he did say he using a A500 style psu thats been converted to be used on the a500/a600/A1200 (300 watt AT psu and he also tryed 3 motherboards (two rev. 2B and one 1D4).and its still being abit of a git to boot. So I'm basically after ideas to see if anyone has any idea why this is refusing to boot if its likely to be the PSU problem or worse case a problem with the BPPC. I have offered the guy a full refund as if the cards not working 100% then it should'nt of been sold, the card did run fine in my system after I managed to get my PSU problem sorted out! The guy knows about the +5V power line to the fan connector but has'nt tryed it yet so any other ideas would be great.

is it on cold boot? if so, I and others have the same problem.
does he have bvision, too? FDD connector power?
IIRC, I didn't need any extra power when using only PPC with A500 PSU.
He probably knows, but its worth repeating: never try two different PSUs at same time on one A1200.

He can try to connect PSU to floppy power connector on motherboard. My BPPC (even without BVision) works bad, being unstable without this "aid". Sometimes it goes, sometimes not..
I know rev 1D4 had often serious problems with BlizzardPPC. I previously experienced it. I don't know about rev. 2B...

My A1200(rev 1D4)/Bppc/Bvision wouldn't even boot without a second power line to the floppy. i won't run a power line to the fan port as this didn't really work for me.

however. i did have the latest firmware (G-REX) on my blizzard card when i got my Bvision, and it wasn't a happy bunny at all. when i reflashed my BPPC back to the latest firmware for the Bvision only, it was fine.

the other thing i have trouble with, is occasionally, i need to "wiggle" the bvision on its connector with the BPPC. as the machine boots up fine, but it won't display a CGX screen. a hint that its having problems, is the bvision mode promoted aga screen is slightly corrupt, and the mouse pointer is a load of dots. a quick couple of presses on the connector and everythings fine.

my A1200 rev1D4, BPPC, and Bvision are solid as rocks. i've not had a lockup, guru, crash, or reboot. :-? i was looking at doing the timing fixes, but i havn't had any problems, so no real reason to...

but the bvision does suck alot of juice. i have an 80Watt nano ATX PSU, plugged into a d-box Amiga ATX to AT adapter.
The mainboard powerfeeds comming from the D-box adapter feed the PSU port, plus a 5V mainboard line goes to the 5V of the floppy port. the drive leads from the nanoATX psu run the floppy, DVD, fan for Bvision, fan for BPPC and the 12V and ground lines of the floppy port.

i wouldn't like to run a BPPC/BVision A1200 on an A500 PSU. i can't say for sure, but i think power may be the problem, plus check which firmware you have on your BPPC.

If he uses the "old" PSU connector then he won't go far.
I converter last month a 200W AT PSU to plug on the old connector. This PSU worked well with my A1230 fully loaded when i powered it by the floppy connector.
But it started to be the apocalipse by the standard plug.
Why ?
The PSU deliver +4.96v, but when you plug it and measure at the floppy connector you only have 4.70v !!!!
0.26v are lost !!!
Any Amiga is unstable under 4.86v...

So guess :roll:
