Amiga 1200 Motherboard re-Hookup

[Aniway]

I have hooked up my replacement motherboard w/ 3.1 ROMs and surely I've done something wrong.

:-? Specifically, I was wondering if there were some sort of FAQ available about how to put together an A1200 properly. I have searched without finding anything, so I come here as a last resort.

The best it can do has been to pop up the purple screen and ask me to insert a disk into floppy drive.
That tells me that the board probably works.

However, no matter what floppy I put in, I can't hear any drive activity beyond maybe one click and then dead silence.  This floppy worked fine before, and it has been sitting in a drawer, so I don't know what could be wrong.

The IDE cable I presume powers the floppy as well as the IDE hard drive that I had with my old motherboard.  I presume I can't boot from that because it was on the 3.0 Workbench.

I don't know if the order matters to connect the power cable.  I have the lights for the A1200 computer hooked up okay.  Further, I don't know how to hook up the IDE portion to the A1200 correctly, as it has 3 different possibilities, and I have narrowed it down to 4.

:-( Can anyone help me?

Thanks,

Aniway

Not wishing to be stupid, but shouldn't your floppy drive be connected to the floppy controller not the IDE controller.

I've had this happen with my Amiga 2000 (the floppy drives should work the same). The drive seems to work okay, but it won't read onything. Try rotating one end of the floppy cable 180 degrees. Let me know if this works.

No. The floppy power cable powers the floppy. The floppy data cable connects to the floppy data port on the MB. The IDE cable DOES power a 2.5" HDD though.

Ok then. I guess I need a total of two cables for my floppy, either of which would not be the IDE.

I`m trying to struggle with the logic on that one..you overheated both my braincells  :crazy:

Anyway, back to the floppy.
You do indeed need 2 cables.
 A flat IDC type (same sort as IDE, just not so many wires!) which connects from the floppy to the floppy header which is top right on the A1200 mobo.
 Just pay attention to getting it the right way round.
 Pin 1 on the cable is the red streak, just match that up with the "1" marked by the motherboard header, and the mark on the floppy.

You also need a power cable that connects to the left of the floppy interface, can`t miss it its a small 4 pin header. This connecter is "keyed" so you can`t plug it in the wrong way.

BTW. Once you`ve got these, if the floppy light comes on and stays on, then the IDC cable is in back to front.

The actual problem was :

1) My 3 gig 2.5" HD refused to work. That same cable, however, was powering up my formerly disconnected 340mb XDS HD external shortly after disconnecting the tiny one.

2) The XDS wouldn't boot because I did not make it Master. Thanks to an online expedition into the Seagate manual archives, I achieved the sort of success that amazes me for being so uncustomarily genuine.

3) The 2.5" drive wouldn't boot at all, even though I have been careful with it and it worked fine last time.

4) The floppy was likely hooked up the wrong way, or certainly doesn't work with the 2.5" drive connected.

Thanks everyone. Now I can wear my shades again  8-)
