During the installation or the Beta version of eBoostr, it asked how much cache to use for the program.  When I changed it from system memory to the SD card, it correctly identified the size of the card (approx. 7711 MB).  The card is formated as FAT32, and the program tells me that a maximum of 4GB can be used. 

The problem is that the slider shows 7711 MB as the max and the box that you enter the size you want to use as 4096 as the max.  I had to change the size to around 2GB in order to proceed.
