Nothing special, just be sure that the INIT in the IDE-MENU installs a FAT32-partition.
If you're not sure when selecting the Auto-Init, select Manual.
Then pop the card in your PC and be sure to format this partition FAT32 (quick format will do fine).
If you have done all of this right, you could be facing the timing-issue on unmodded MyIDE-I.
The SIDE fat32-loader has no retry-function
