A1200 boot problem - help!

[scuzzb494]

I had this with a hard drive on my towered A1200 and a guy pointed me to a utility called ' SlowBoot ' .

http://aminet.net/package/util/boot/SlowBoot

...The problem with buying a large IDE drive is that it has a long spun-up
time... When booting from cold you have to bootup and then reboot...
SlowBoot fixes this

May help.

Hi blakespot, have you sorted the power supply problem yet and got things up and running.

Ok.

I tied the orange and "brown" wires together (though an online shows it half orange / half brown and the label is 3.3VDC, 3.3V Sense).  I've got the green to ground also.

Fired up and same thing, blip and nothing but a fan pulse at first.

After testing, I finally found it works with everything wired up EXCEPT the Amiga 1200.  I have:

- CPU fan
- Case light
- CD ROM
- HD

but only when I unplug the A1200 does it work.  Could there be a wiring issue here?  The power plug I am using is that flat, 5-6 pin one with a latch.  It plugs into a custom cable that came w/ the case that goes into A1200 power jack.

It's a 300W power supply -- how could this be overloading?  Or is the A1200 mobo dying?

Thanks.

Hmm... I need a few moments to think about this one...

Hi blakespot...

We seem to be getting nowhere fast here, so I'll make you this offer, the choice is entirely yours but I am quite happy to do it if you wish.

If you would like to send me a personal message and give me your telephone number, it must be a landline and not a cell phone. Then I would be more than happy to call you as it doesn't cost me anything to call to the USA. If you wish to take me up on this offer make sure you include the international code for the USA as i have forgotten it. I reckon we might be able to sort out your problems if I can speak to you, rather than typing back & forth here with limited info.

Cheers :drink:

I was thinking I'd try the PSU in my C-One case...but it occurred to me last I messed with it, that nearly unused PSU started doing the SAME THING there.  Power on for a blip, then nothing.  So that PSU likely would do same on the A1200.

WTF is going on here?

Sorry blakespot, but I don't think I can offer you any more advice here. If you wish to take me up on the offer of calling you then I would be only too happy to do so, but without knowing more about everything your trying to do there. I don't think I can be of much more help.

By the way, IIRC there is a program on AmiNet that can control the ATX PSU so you can shut the amiga off with a CLI command or something.

Read about it years ago and always wanted to try it.  I think it used the joystick port to open the power wire on the PSU.

Good luck!

Only have cell, sorry. Thanks for the offer, tho!

What is the likelyhood that something has happened to the A1200 motherboard (that I got NEW in 2004 - rarely used after) that made it short out or something?

I've never connected orange and brown to get a 20 pin ATX psu working (is that a 24 pin thing ?). Can you just try it without those two connected, leaving green and black connected to see what happens ?
Be aware that these psu's need a load connected to function properly.

Take one of psu's floppy power connectors and put it to mobo's floppy power connector, so that you can feed mobo that way allso.

Hi blakespot

Had any luck yet...

That move makes no difference, FYI.

Nope. Gonna pickup an ATX PSU today from the store and give it a shot.

It's all particularly painful as I just got a new X-Surf ethernet card for my Amiga 2000 and I can't get a TCP/IP stack over to the Amiga 2000 w/out using the A1200 (which has ethernet already) as a bridge...

OMG you won't believe what just happened.  Stay tuned.
