A1XE : cpu fan not running, no video output

@ Framiga :
Thanks I will try as soon I get home for the speaker. As for the fan, I tried several times to invert, revert etc this bloody cable, even to put it on the second fan connector but no , it does not work.

At this point, could be better, if you test the fan out of AOne mobo.

If the fan is in short, the power supply protection circuit, start.

Test the fan on another PSU or any +12 volts source. The same for the GFX board (on a PC)

At this point, I'm going to play devil's advocate -- contact Eyetech.  You've been running the board without cooling, you apparently had a power supply flake out on you -- it may not be dead, but it seems you aren't having luck bringing it to life.

Perhaps they can put you in touch with a dealer (with the hardware on hand, like a spare processor card and fan) to debug the problem, or arrange for a board swap at the cost of some shipping.

Never heard before about this reset bug in Radeon card (mine is AGP)

Maybe the fan is dead? Also maybe try booting it without the fan hooked up, maybe it has some shortcut or something.

@ Lionstorm

Was Amiga.org your first choice for technical support?

I know that there are many experts here but the first thing I would have done is contacted the supplier or eyetech for technical support.

The hardware is under warranty and if it has a fault or if you need help setting it up why not try the official channels first. I am sure they will be willing to help :idea:

[lionstorm]

@ GadgetMaster : I beg and please for help everywhere to have most chance to get the reply I am desperately waiting for. On A1SEdev, they are that many messages that mine could easely be sunk and forgotten.

TO ALL : fan is working now, stupid me I plugged the fan cable in all 3 positions instead of 2 and 3 only. But still no video output so I connect a serial cable between my A1 and a PC running Mandrake9, install minicom, set it up at 9600 bauds 8n1 and power on the A1. I get a screen with U-boot etc, board, dram, flash and then  this
*** warning, bad CRC use default environment

and thats all. Hooking up HD and DVD, KB and mouse but caps key does not light on.
So still stuck although something is working now.
Thanks for the help but still need more

@Lionstorm

Exactly what brand videocard are you using? Is it Gigabyte? Is it Powercolor? Is it Auriga? etc etc...

[Rogue]

Lacking PCI reset is a bug of the motherboard.

The board has a PCI reset, and the firmware triggers it, unless one happens to have a very old revision of the firmware, in which case it can be updated.

I've never heard about such a problem.

The only problem that I am aware of is that the Linux kernel doesn't properly trigger the reset, but that is a software problem, and outside of my area of expertise.

[Rogue]

But still no video output

Radeon 7xxx should work. What exactly happens? Hang during graphics card init, or a "VGA: OK" and still no display.

What revision (date) of the firmware do you have? The recent update fixed a problem with certain brands of 7000's not working.

[lionstorm]

@Rogue : no more output after the warning line (no VGA ok), so I guess A1 hangs. Graphic card is ATI radeon 7500LE 64Mb (no ideo whether it is powercolor or something else).
revision :
U-boot 0.1.1 (Apr 3 2003 - 14:44:24), Build: 04/03/03

U-boot 0.1.1 (Apr 3 2003 - 14:44:24), Build: 04/03/03

Try the latest build of the firmware from the A1G3dev's file area. It is known to fix some issues with certain brands of Radeon hardware.

[lionstorm]

sorry to be dumb but where is the file area ? the only U-boot I could get is from sourceforge.net, which is currently having U-boot 0.4.0 but the problem will be how exactly to transfer and install the file (3MB) on my A1 without any working drive and video output besides minicom.

Write me a private mail (Hans-JoergF@hyperion-entertainment.com) about this.

One more question... Have you tried moving around the ram? Some mainboards is a bit picky of which slot the ram is plugged in. And also... You should test the gfx card in a pc or something, to see if it works there.

ok knowing how most ATX motherboards will not boot or complete a post when there is no fan or any working fan hooked up to the power supply, I would disconnect the power supply from the motherboard, and get an adapter for the cpu fan and connect it directly to the power supply and see if it works then, also if you have a multimeter you can check the voltage output from the motherboard cpu fan connetors, if good then you know you have a bad fan.

if you were to ask me, off the top of my head,  I think that the whole problem is with the fan, so I would get a new fan

[WarPiper]

remember, if your fan is bad, or not properly connected, your computer will not boot, post or even (some cases) beep.

[WarPiper]

oh ok, fan is now working, nevermind my last post
