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?

@bamiga2002

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

@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??

@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!!

@delshay

whats the performance like? is it playable?

@delshay

where can i download the warp emulator? also what will it mean by not being able to run it in 16 bit mode? presumably a lower colour count?

@delshay

hello again :)

Yes me too please - if anyone knows how to rectify the flickering on a Blizzard PPC + Blizzard Vision I'd be most grateful! (Have also got a CVision monitor in devs/monitors folder)

Cheers!

@nubechecorre

Hi there - its ok - I realised that because the other modes had = there too, so I copied that.
Very confused as to why this doesn't work. I thought it might be because I had too many screen modes listed, so I thought I'd delete the 800x600 ones as I don't use those, and then it didnt boot correctly (had to go in the OS 3.1 and fix the tooltypes to get back in to OS4!)

Are the 800x600 modes required even though Im using 1024x768@75? (monitor info confirms that this is the true resolution)

Sidestepping - when you select the AGA mode in Quake - I assumed that this meant it would output the video on the RGB and composite video ports on the Amiga - is this not the case, because all I get is a dark cropped unuseable output on the BVision output.....

:)

@nubechecorre

Thanks! I've added them and saved it but they don't appear as an option in quake, or as an option under prefs/screens either. I've tried rebooting and they still don't appear :(

Am I missing something?

I've got a Blizzard PPC & BVision setup running on OS4.0 but when loading and selecting the CyberGrafx driver, I only get the choice of 800x600 (which is repeated 3 times in the list of available resolutions) along with 1024x768

When I use any of the resolutions, the game loads and plays but I get a horrible flicker/delay going on... almost like the frame buffer has a delay or something... has anyone experienced this? I suspect its because I'm running it at a higher resolution. Is it possible to run it at 320x240 / 640x480 using the same cybergrafx driver? if so, how do I change it?!

Cheers!

@delshay

woah thats one seriously modd'ed blizzard card. Would love to see some photos of your cooling system!! to see how you've managed to continue using the original rubber feet!!

I've simply elevated the whole machine up by approx 1 inch on to wooden blocks to allow a full heatsink & fan to be attached to the bottom - and added a hard drive cooler to suck out air from the case. Also added few fans & heatsinks inside on the GPU + RAM chips on the Bvision too....

What did you do to it to get it to 300+ Mhz?

@badgerme

yeah I think your right on this one :) Think I'll leave it as it is..... Shes a beauty when shes going with a Bvision & 256mb ram :D

For anyone else reading, it also soft resets perfectly fine too - so it only happens for the first time when its turned on.....

@delshay

cheers buddy - so do you think its safe to pull out the power connector during the boot up procedure?

@delshay

I think you've missed my point. When I have the floppy connector connected straight from the power supply to the main board - the 5v main line reads 4.97v - but DOESNT boot from the hard disk or floppy drive. It starts to, but then simply stops!!!! Surely 4.97v should be spot on????

However, when it disconnected, I get about 4.78v - which makes it boot from the hard drive/floppy drive.

But in order for machine to turn on and to recognise/power up the bppc card, i need to have the 2 connectors connected first, then I have to remove the floppy main board connector as soon as the green light comes on, to get it to boot!!!

So to summarise, what I do to get it to boot is:

- Both power leads in (4.97v)
- Green power light goes from dim green to bright green
- Remove Floppy Power Lead (from PSU) voltage drops to 4.77v whilst machine is still on)
- System boots!

If I don't pull out the floppy power connector after dim green light has gone full green, then it starts to boot, then simply stops.

Otherwise, if I leave both power connectors, machine comes on, starts to boot, then stops and hangs on the light green screen.

Haven't got any cooling issues - I have a custom cooler on both of the bvision and bpcc cards that is plentyful!

I do have a wierd power issue though. I have the standard amiga power connector plugged in from the 250w atx (new) psu, and I have the molex connector plugged directly on to the motherboard (with the 5v line reading 4.97v)

However...

What is REALLY strange is that, with both power connectors attached, the machine turns on, but never boots from either a floppy disk or a hard disk!! It starts to boot, then simply stops and goes no further than the light grey screen.

If I have just the standard amiga power plugged in, its not enough to power up the blizzard boards, and thus struggles to go from the dim green light to the full 'on' green light.

So... what I (annoyingly) have to do each time in order to boot, is to have both power connectors plugged in to get the dim green light to go to the full green light...

then as soon as thats happened, switch off the other molex connector going to the mainboard to get it to boot from either a floppy or hard drive.

This I add works beautifully - but I'm worried that it could damage by Amiga.... as surely its not a good/safe thing to do long term??

I must also add, that with power connectors plugged in, I can access the BPPC option menu without any problems, and I can see the boot rom screen also, if I don't have a hard drive attached, or a bootable floppy inserted.


Any ideas anyone?!?!? It seems to me that it only likes to boot with the 5v main line is at 4.77v (which is what it is when I remove the 2nd power connector)

Very strange!!!

Hi all - I've recently just acquired a Blizzard PPC 210mhz with a 68060 50mhz processor on board. I have a desktop A1200 with a brand new 250w ATX external PSU (from amigakit) which has a standard Amiga power plug as well as the molex connectors coming out of it.
Could someone tell me the best way of powering my card please with this setup please? I've seen some people connect the 5v line from a molex connector directly on to the 2pin fan connector on the blizzard board. Is this safe to do? Is this the best way of getting power straight on to the board? How does every one else do it? Regards. Terry

Would anyone be interested in in buying my working classic OS4 system?

A1200 Desktop Case with the following installed inside:

Blizzard PPC 603e card 210Mhz with 68060 50Mhz & SCSI
with 256mb 60ns SIMMs installed on it

Blizzard Vision Graphics Card

2gig Compact Flash HD (with OS4 installed)
New ATX 250w PSU from AmigaKit.com

All have plenty of cooling and has been working for some time now without any problems.

I can supply with it the OS4 CD (unregistered) along with a Slim CD laptop drive too.

Offers anyone?

@tonyw

lol - yeah - I think I get the idea... so that is a 'No' isn't it - just want to be sure! :)

Just a quickie - do I need to reinstall OS4 if I've changed my Blizzard PPC card from an 040 model to a 060 model? (Different card - not an upgrade)

Cheers!

@Curty

Id give ya ?90 for it... I'm not far from South Wales - could collect?
