I was fighting with this long time ago. Then I thought maybe I need Ultimate 1MB for some reason (maybe there is ramdisk to load the ATR or something). Anyway, now I have SIDE2 and U1MB in my Atari 65XE.
I've read many documents. I know I should press L to load ATR. But in all these cases I get message implying there is no FAT32 partition, or no PBI or no APT device.
What I understood is that somehow I have to run fdisk to make partition.
I have read docs and seen videos.
Yesterday I managed to extract FDISK.XEX from an ATR with these utils.
It starts but then it says "Can't find APT device"
I also installed a thing called PBI.
I am not exactly sure what PBI or APT means. I need a mental map to understand what I am dealing with.
But I know I have to somehow make it possible to see the cart as a disk or something. But nothing works.
Also, in the docs it's implied that FDISK and other tools are loaded by default in the cart. But FDISK is not there. I am in SpartaDos, at D1:. I thought maybe I should write CAR: and nothing happens but shows me again at D1:
Is CAR: some storage in the cartidge that holds those tools? There are video tutorials someone writing fdisk and running the thing. But I get an 138 device error. Of course I tried the other solution, extracting the FDISK.XEX and running it trhough the SIDE loader.
There is more. I somehow manage to install a PBI driver 1.0, so I get the message when I boot to spartados that PBI is loaded. Don't know if this changes something. But now I have hard time to get into the loader. Unless I disable SIDE2 in the setup menu (with Help+Reset). But I don't understand the logic. I thought SIDE2 was that loader. So, I get into the LOADER by disabling the hardware. And if I enable it w/o button (what does this mean?) now it always boots in spartados no matter what. Before that, I had to Turn Off/On the atari from the switch, to boot to LOADER, even with SIDE hardware enabled. A reset would later get me to DOS but not loader. I don't understand, it's a bit convoluted. But now it's worse.
I'd like to understand the logic. Maybe though I am failing, because besides that there is something wrong with the CART. Maybe not.
