Setting up Bvision

[Mendel]

The Bvision fan came off when I plugged its power plug off as I was trying to check its connections and tighten the screws a bit more. So I have to take it off until I can arrange new heatsinks and fan for it. The noisy one had to go anyways.

It will take also take a while before I have the time to make clean cwb install from scratch, starting by remaking all the partitions to a different cf card and then going from 3.1 and 3.9 installs to new hdf and then upgrading to cwb39.

Meanwhile, I am putting the 1260 back on for occasional whdload use. Thank gowd for no fans.

Not giving up, just need a break.

Okay so I am looking for someone who has Bvision compatible heatsinks and fan so that I can send the card for the person to fit them or alternatively if the heatsink and fan can be sent to me with instruction on how to attach them.

Or I could send PPC and Bvision and CF card to someone if anyone wants to try to not only fit it with cooling but also make them work together as I sure can´t seem to get them to actually work. I am worried I might burn the Bvision if I put it on again with the fan seeming to not stick to the chip.icard

I´ll also ask fitzsteve if I can send it back to him to see if I have broken it somehow or if I am just noob

I have some small heatsinks that are self-adhesive and I remember using them when I had a BVision. I could send pictures of them. Just get a small fan somewhere for the BVision. Don't worry burning the BVision, it won't burn without extra cooling anyway if you don't enable overclocking from the CGX4 software. It still does get hot though.

If you're willing to make a trip to where I live we could set the hardware & software working, I have some experience of these things

 

[Mendel]

Thanks for the offer. Kind of a long trip it would be.
Fitzsteve says the problem is probably that I am not getting enough 5v to the BVision. It would make sense seeing as the PPC card also did not like to work with a 300MHz or 330MHz processor when Stachu tried to upgrade it. So probably voltage problem. I think I may send bvision back and/or sell the BPPC and try to buy other ones... unless you think you could do something about the possible voltage problem too

 

[Bamiga2002]

You should do the old trick that is connecting a +5V lead to the PPC fan connector from PSU. That did it for me in those days

 

[Mendel]

Okay so it is decision time. Either I send the Bvision back to fitzsteve for a refund or I do this quite elaborate voltage hack. Is there a picture of where exactly to put which wire? I have the amigakit psu with extra cable loom.

I am thinking I should try to exhaust this possibility too. Okay so which cable, where? I have soldering iron if need be and I can solder a wire together. Problems only if I have to solder a very small area where there is danger of shortcircuiting stuff as my hands have habit of shaking.

I could use floppy power connector or molex. Probably simplest to use wire from floppy connector if that is possible. I dont know which is 5V wire but I reckon it would have to be either the yellow or red... and connect that to the fan power connector? How does that even make sense you mean to the backside of the connector? solder it to the pin where the fans black wire goes or to the one where the red wire goes?


Oh and the fan is not necessary? Lets consider if the card has been previously overclocked, is the clocks stored in the card or in the hard drive/software of the amiga? That is, how do I know if my bvision is running overclocked or not and if it is safe to use without fan? Is it always factory default clocks unless special software is actively used to keep it at higher clock?

wait just a minute... could it be as simple as me having to read the fragging manual?!?

I need to connect floppy power connector from psu to the floppy power port of the A1200?

edit: nope that was not enough. I took the risk of running the rig with ppc and bvision with only a heatsink (attached as best I could) but no heatsink fan. Here´s hoping it didn´t burn, at least no smoke

now for the wire to the fan connector. Which color, which pin?

 

[Mendel]

Another case and motherboard.

same cf card, same power supply, same ppc, same bvision. New geeeenius way to attach heatsink. (2 wirestraps)

Same failure.

Still havent figured out what is the 5v cable and where to put it.

 

[UberFreak]

Extra power through the motherboard floppy connector wasnt enough for me, still had major problems getting the system to even boot.
Eventually I had to feed 5V directly to the BPPC (not via the fan connector, I know of cases where doing that burned the connector tracks as they werent able to handle the current pull through there!).

 

[Mendel]

What color cable and where exactly? I need to very carefully examine if the area is solderable by me

 

[Mendel]

Frustrated, I gave up for now and went for the grex. And I cant make that work either.

I made a new thread about that so feel free to give any ideas there:
