If the caps lock is only blinking when the KA47 and SD card are connected then the chances are is that the SD card itself is not properly configured causing the lockups.

Try connecting it all back up, boot from the HD install floppy disk and start again from scratch. Much easier (and faster) than diagnosing filesystem errors.
I'll try that. I don't have physical WB 3.1 disks sadly, so will have to do it on UAE as I have the ADFs thanks to Amiga Forever. I'll post back if I get anywhere.
 
Don't know if its a factor but it doesnt boot even if there's no SD Card in the SD2IDE adapter... so long as the adapter is connected. Should it not boot then?
 
Irrespective of card or no card in the adaptor, the Amiga 600 should still boot from floppy disk.

Suggest you get a 44pin ribbon cable, plug it onto the mainboard's IDE header and the SD adaptor on the other end. See if that solves your problem.

Don't forget, coloured stripe on cable goes to pin 1 or to the end with a triangle for the SD adaptor!

Thanks. Looks like it is some kind of issue with the setup or something. I've formatted the system partition and reinstalled Workbench 3.1 on it in an Amiga 600 configuration in WinUAE using official ADF files from Amiga Forever. It boots perfectly in WHD load but not in my A 600.

I am getting a green light on the SD2IDE adapter after boot with the KA47, which tells me I'm close... I tried a ribbon cable but seems the ribbon cable may be faulty as I'm not getting the green light even with that. Ironically I can boot from floppy using the ribbon cable, but I get no green light and it's not recognised in the boot menu. With the KA47, I get nothing, no boot menu, no floppy activity. Nada.


Seems I'm having the worst luck getting my miggy perfect. And I'm so close! It really stinks. I've lost 4 weekends trying to get this working now.

Anywhere I can get a verified working 44 pin cable at very short notice? 😂

Is there a master slave switch on the KA47 or the SD2IDE adapters by any chance? I feel like it's going to be something silly like that
 
Nothing like that on the KA47, not sure which SD2IDE adaptor you have. Able to post a picture?
 
Cant see any burnt tracks or anything else out of place with the interfaces, just the usual bent pins that everyone seems to acquire lol.

What about the SD card you used to create a new installation via WinUAE - did you run it through Windows Diskpart beforehand? What capacity cards are you using?

The master (my OG card) is a Sandisk 16gb micro SD partitioned into 4 x 4gb partitions. All show up fine in WinUAE as mentioned. But even if I put a blank SD in or no SD at all, same issue.

Okay, I suspect the problem lies with the way Workbench 3.1 accesses partitions - 4GB limit and all that..

Try the following using WinUAE:

Load HDInstall floppy disk and set up the SD card as follows.

Make ONLY 1 partition of 512MB or smaller (make sure you select Bootable). Save and exit back to Workbench. Reset WinUAE and reload HDInstall. hopefully you see the new icon for the HD partition you created. If so, format it using Quick Format, never full!

Run the HDInstall and copy Workbench to the SD card. Once complete, close WinUAE and plug the SD card into the A600. Switch on and cross fingers!

Sounds like a plan! I'll give this a shot next time I have a free few hours.
 
Okay I realised I actually have some time while the missus is taking a bath so I went and did this. Same issue sadly....

May have to face the possibility that there may be something wrong with the Amiga even after it's been recapped. It can't be the PSU because that can power the Furia 020 just fine if I load up a disk game, eg Frontier. And it's clearly working. I'd also expect to be able to get to the boot menu at least but can't when anything is connected to IDE...


I've ordered a pre built compact flash card with adapter instead just to try that out. I doubt it will work but on the off chance it just doesn't like the SD setup. I'll update and do the same with that if it doesn't work off the bat when I receive it.

If the above doesn't work, I may have to keep this miggy floppy boot only. Maybe I'll consider a floppy emulator for it. Are they as straight forward as WHDLoad to run?
 
A funny thought occurred to me, might there be a problem with the Kickstart 3.1 chip itself?

Can you remember if it came with the A600 or did you pull the original and replace it with a 3.1 sometime in the past?

A Gotek will only allow you to boot ADF files, no difference to running it as a straight floppy disk machine.

Edit - Has the A600 been recapped?

I bought a 3.1 ROM for it recently. Officially licensed Amiga Forever chip... swapped it myself. Yes its been recapped.

I've now got a CF adapter from Amiga Kit. Curiously enough whether I set it to master or slave it skips booting direct to the "insert floppy" purple screen. At least its not hanging now but it's also not picking up the drive. I have tested the CF in UAE and it boots Amiga Kit's custom install screen right off the bat....

On the A600, I can get into the boot menu with double mouse button press on boot. It isn't showing the HDD.

I've spent so much on this thing now... Guessing next, I either need to try another ROM or another motherboard.... :cry:


HALP!

Okay there has been a development. I got in touch with the guy I bought this from who told me it previously had some damage near the IDE port which was repaired by Amiga Passion (now Retro Passion) alongside the recap they did on it.

After that revelation I can only assume the old damage has resurfaced, ie whatever they did to fix it has failed. Guessing it had a leaky cap during the previous owners time with it that did some damage...


I need to get in touch with them I guess.
 
Hopefully it will be a simple thing to sort out!
Indeed. I've been told it was repaired and a new IDE port put on to be safe. But obviously something has gone wrong somewhere, so I'll have to pull the board out and check both sides carefully. No idea what I'm looking for. I'll post a few pics and maybe someone here will spot something and have some knowledge how I'm best approaching a solution if I don't.

I'll check port solder joints first if nothing else stands out. It would make sense if one of the pins aren't properly connected or something I guess.
 
Solder bridges or stray blobs of solder are the usual culprits. Take a good close look at the rework and the surrounding areas.
