My first TF536

I was looking at the CF card layout and I notices that a couple of lines weren't connected on the adapter.
It just involved adding a few wires for the bios to detect it as a faster device and that worked like a charm.

I have no more recolection of the details as it was a long time ago, probably your CF adapter and card support it and the other CF cards do not.

SD Cards though. MY 17 second CF boot time is probably almost as good as it gets.

Ah, found someone with the same issue and a writeup.

It wasn't that pio mode 4 wasn't available, it was that the DMA wasn't available.
If i'm correct the Amiga will not support DMA, so that will not help.

But it is possible that more modern cf cards expect to find DMA and not PIO mode 4 and that that may cause the problem.
Sandisk always had a tool to configure some of the cards but I haven't seen that on newer cards.
The above article goes in to that too.

Maybe getting a non DMA version of the card will work:
So not these:

Thanks. That might be it. The cards that take long to boot actually cause the machine to wait for many seconds before it even does the single floppy drive noise. Some 20-30 seconds.

I made my own relocator this morning just for fun. It uses recessed female headers for the output socket to ensure the acccelerator sits lower. The female headers sit just to the left of the Kickstart ROM with about 1 mm clearance. It turned out pretty nice for a DIY circuit board. I didn't have any single sided copper blanks so I had to use a two sided one, so the bottom copper layer is a ground plane, but it could easily be CMc-milled from single sided board. It places the IDE in a super convenient location for using a short IDE cable, though I have a long one in the photos.

Sweet. I like the organic curves!

Today I received the RAM for my second TF536 and it works. Very cheap RAM: https://rover.ebay.com/rover/1/711-5320 ... 2444631488
