Ok- this follows from the CF formatting thread... Long dramas getting the CF adaptor in my machine... finally get it connected, and it doesn't boot.
Tried restoring my previous setup of noisy IDE 3.5"drive... and it's not working anymore!!
What could have happened?
-
Did you have a 44-pin CF adaptor? And if so you didn't connect it the wrong way around did you? Pins 41-44 carry the power for the drive on a 44-pin IDE connector. If you got it the wrong way around some damage may have been done.
Edit: Just saw the pics of your adaptor set up.

If you plugged the CF Adaptor in the way it looks on the photo, I think you may have plugged it in the wrong way. I'm not sure what damage that may have done, or whether it would damage only the card or both the card and the IDE on the a600 MoBo. :-(
-
the red stripe "usually" goes on the same side as the power connector.
-
On a 3.5" Hard Disk yes, it usually does. On a 2.5" <-> 3.5" adaptor however the 4 pins on the Molex socket are pins 41 to 44. So the pin next to the Molex plug is generally pin 40. Unless the maker wanted to have some funky tracks on the PCB.
-
well that would be an easy mistake then!
-
So you think I killed the motherboard? That's really bad news... Stupid adaptor shouldn't let u put it in backwards!
Is it fixable? There must be SOME hope?
:(
-
i was just thinking that. to my mind it's badly designed and cheap. don't give up though. have you tried the a600 on it's own? i've seem them survive worse stuff. after all i own some and they are still working!!! :lol:
-
It's still alive- there's a kickstart animation... but it's not detecting the HDD at all, and I'm getting really depressed about it.
-
I'm not sure with any real certainty that you've damaged the boards IDE controller, but the fact it no longer boots the drive that it used to is a pretty good indicator. Which custom chip handles the IDE on an Amiga 600? You might need to replace it. Though surface mounted chips are really hard to replace. AmigaKit sell A600 MoBos for around $40. I also see them come up on eBay fairly frequently.
Just go over everything slowly and make sure you have the old drive hooked up the way it was before you installed the CF card. You said you had a 3.5" HD in there? How are you powering the 3.5" HD? Did you reconnect the power to the 3.5" HD? That's a mistake I used to make all the time. I'd put a 3.5" HD on my A1200, then freak out that it wasn't working only to find that I hadn't connected any power to it.
-
did you see any smoke or smell anything burn. or a component type smell at any point? or is there any burn marks?
-
I connected the power, so it wasn't that... but there were no burn marks or anything like that either... no smell...
confusing... I don't want to have to buy another machine! darn it...
-
i bought a pc case at christmas 2001 for a downstairs computer . i was just telling my mother how great usb was and how you can just plug stuff in and out while it's on and boldly demoing it to her when i plugged a usb psx joypad adaptor in it and could smell burning. the joypad would no longer work...
inside 2 resistors had burnt off you could see the burn marks. it ruined xmas i know how that feels! i think the usb port had been wired incorrectly. best to avoid cheap stuff from china... :roll:
they should be made so you can't plug them in the wrong way.
-
I fried the controller chip on my Atari Falcon when I put one adapter the wrong way round. There was a puff and lot's of smoke though...
-
Would anyone in Brisbane like to donate an Amiga600, or 1200? I was really looking forward to breathing some new life into this machine & do some live music/art projects...
Major bummer.
-
might be the ide cable, i've had hordes of problems with them, until i finally got one from amigakit
-
Xamiche is right man, unfortunately you had it plugged in the wrong way (I suspected, but didn't look too hard as I was at work when posting in your other thread).
The IDE bus can handle a device being plugged in the wrong way for a few seconds, but eventually it'll die...and I'm sad to say yours has indeed been fried :-(
There is an A1200 mobo on eBay.au at the moment...maybe time for an upgrade, given the excuse you now have? Tower conversion anyone? :-)
PZ.
-
i didn't realise you are in oz. that makes it worse. i prefer a1200 to a600. although it's cute i never use mine. is it sentimental to you? i'd go for the a1200. unless you already have one of course.
-
I would like to get a 1200 eventually, but can't afford it at the moment. I need to know if this thing is definitely dead, as I only did very short tests with the IDE setup, there was no burning smell or anything...
and I've definitely done this on a PC previously- it didn't boot, so I turned the cable around.... no problem. why should it burn out?
What should the bios be showing? I have DF0 and CC0- and I don't know what should be there...
Still boots from floppy- tho I don't have many floppies that actually work these days.
-
If it detects any HDD on the bus, be it formatted or not, it will show HD0 when you enter "boot options".
I am assuming that by "BIOS" you mean holding both mouse buttons for start preferences when you turn it on?
PZ.
-
Yeah- the dual mouse button thing... (is BIOS an inaccurate description?) No HD0 shows up...
what is CC0 and why is it listed as a boot option?
This is going to take a while to sink in... I've been looking forward to getting this up and running for months, and have been through a lot of crap to find parts etc...
Stupid a600 piece of @$!$%!^!^

Only if there are partitions on the disk. It won't arbitrarily show HD0 just because there's a hard disk there.

It's called Early Startup Control. And it should show any properly configured storage device. Harddisks can be assigned different names but usual ones are HD0: or DH0:. The 0 can be any number of course. Usually you would number the paritions.
CC0: is the PCMCIA card slot.
-
If you want to be sure you fried your A600's IDE port, you should connect the HD the right way with power and then run HDToolBox to see if the system can see any drives on scsi.device. If that fails you have succesfully fried your IDE port.

Mate I feel for you, do you have an old laptop that you can take the HD out of to test the IDE port on the 600 ? Or maybe test the 3.5/CF drive on the PC?
-
CC0 is the PCMCIA port.
Sorry to hear about this man, I know the agony you are feeling :-(
PZ.
-
Yes, get back to basics, throw out all CF stuff and see if it is alive.
I have hooked up IDE drives backwards on an A1200, I don't think it fried it...
BTW, get a better CF adaptor, yours is crap.

I do feel for you, stinks, but you'll get a machine going.

A PC 3.5" hard drive only has 40-pins, and it's cable doesn't carry the power for the drives logic and motor on it. So you can get the cable around the wrong way and be okay. However with a 2.5" drive, having no molex power connector like a 3.5" HD, the power is carried on cable via pins 41 to 43. (41 = 5v, 42 = 5v, 43 = GND) If you get the cable around the wrong way you're dumping the 5volts from 41 & 42 into pins 3 & 4. Which are data lines.
If the A600 still boots from floppy, like someone here suggested, connect your old HD, boot from floppy and use the HDToolBox to try and detect the HD.
-
@Xamiche
Yeah, that does makes sense about the 2.5" power. fingers crossed for you man...
-
Look at this (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=310042099909&ssPageName=STRK:MEWN:IT&ih=021) Amiga Retro Experience always had spare boards in stock. If they are not currently listed, send him a mail.

This is a long shot. Sometimes, when I pull ribbon cables from hard drives, the end connectors separate a little. Everything looks fine but one or more connections could be lost. This is consistent with having no indication or smell of failure.
Examine the cable and try to press the connector halves back onto the ribbon. Better yet, replace the ribbon cable.
Good Luck!
-
I don't have any floppies with hdtoolbox on it... :(
-
Tenacious I could kiss you! WOOOOOOOOOOhoooooooo!!!!
The frikkin cable had come loose at the motherboard end- not noticable to look at! :idea:
*dances around* It's working!!!!
Thanks guys!! :-D :-D :-D :-D
-
Very, very good news man! :-)
PZ.
-
I love a happy ending. That's great, man.

Not in that specific adaptor! It inverts the bus, so the picture is right!
-
That's great news RedWarrior. :-)
Great news indeed.
-
Whoo Hoo! Another happy landing. Good way to start a Friday.
:-)
-
Glad it worked!

aha! we were all rooting for you.

Funny you should use the word 'Rooting'. Here in Australia rooting means f**king. I get a very x-rated visual from your comment.
:-P
