OK, first, can you downsize your screenshots to 25%?
Remove them and upload smaller pictures.
Can't see all at once
FAT32 is the PC-partition on your CF-card, so you need to put your card in the PC.
It will see a freshly prepared unformatted FAT32-container and asks you to format is.
Say: yes.
Than copy the files you need to the card, safely eject, done.
These files you can load with the atarimax fat-loader found in your boot-menu.
Your screenshots:
MyBIOS uses a different partition on the card, specific for the MyIDE-hardware.
Error-160 is a standard message for a unreadable format.
Format the drive before doing directory.
But: Please consult the manual and then the quick start part.
I recommend not to have a 16mb partition as drive one.
MyDOS has some quirks and when it does, you need a standard drive 1 to recover.
So D1: 720s SD and D2: 65535 DD.
Use D1 for system files only and D2 as you like.
After setting them up in the MyIDE-MENU, you need to (re-)format them with MyDOS.
But all is explained in the quick manual.
These partitions are only accessible on the atari using mybios.
Later,
