A1200 {bleep}ed up: what happened?
« on: November 14, 2008, 02:31:33 AM »
Well, I had the suspicion but it's now confirmed: my A1200 is screwed up.

At some point after performing an ATX power mod (i don't know exactly what I did because it looks just like the mod should look, I wired the ATX connector to the motherboard), it got {bleep}ed.

Now, it seems an issue related to teh IDE controller or maybe the CIAs.

Whenever I power up the computer with no drive connected, it takes longer to boot, but it boots to the kickstart screen and apparently the drive tries to boot from floppy (I don't have any bootable floppies with me to test more).

When I connect my CF-IDE adapter, nothing happens. If I press both mouse buttons to get to the Early Startup menu, it would get there but no mouse movements are recognized. If I disconnect the CF-IDE device, the mouse works fine.

If I connect my hard drive, the amiga makes a slight noise (not even a blip, but a noise similar to a bleep), and flashes very briefly in red, then gets stuck in a (not completely black) screen.


Does anybody have the slightest clue of whats going on here?
I thik I could boot from PCMCIA and use it but I am super pissed off that it got broken for no apparent reason, unless the instructions I followed for the ATX plug were wrong or I severely {bleep}ed up somehow.

Help apreciated :(

Almost definitely a CIA issue... on early startup I got DF0, DF1, DF2 and DF3 even when there are no external drives connected...

Maybe I can use this machine through PCMCIA but I can only wonder what else is non functional now that the CIA is busted.

 :-x

This didn't happen before so I guess that the CIA got fried up after  sucessive power ups. How would the CIA be related to the IDE controller? And what could I have done wrong on the ATX plug wiring that could have fried the IDE controller? There are no bridged connections, no shorts!

Did you pull that baby out and scope it for damage? I fuXrd the IDE on an A1200 a while back (can't remember what I did), repaired a trace on the backside and it was fine. Hope you figure it out!

I wonder how a trace could have got fux'd, since I treated this thing with utmost care :( I definitely doubt it.

Also, seems like the CF card got burnt. Smells like plastic burn and all.

I have no idea of what happened here :(

Impossible, the CF-IDE adapter fits in only one way.
The second time, maybe the adapter got moved. This is when everything got even worse, I believe.
