What is the maximum SD card size that the Multi-Loader can handle?

Resolution:
A 2GB SD card can be used.  However, the card supplied is 4GB, so this is a SDHC memory card. It must be formatted in FAT file system to be recognized with the Multi-Loader.
Indeed, if the card is formatted in FAT32 file system (this is the standard for SDHC memory card), the card will be not recognized with the Multi-Loader.
It is possible to format the SDHC memory card with both Windows 7 and XP operating systems.
