The SD card is subdivided in 8 MByte disk volumes 000-254
Volumes 0 and 1 are formatted FAT-16 to later be used as a means of 
transferring files
Volume 2 is designated CP/M 2. The system track (track 0) contains a 128byte 
bootsector, CCP-CP/M 2 and BIOS
Volume 3 is designated CP/M 3. The system track contains a 128 Byte bootsector,
CP/M 3 loader and CCP.COM
The contents of the remainder of the volumes is listed in "Volumeindex.txt"

You need to get creative in loading this on the SD card

I generally just concatenate the relative files and use dd (direct imaging software) to copy the result to the SD card.

Once you have one working image you can use the DOWNLOAD utility to transfer 
images to the system and use PUTSYS to populate other system tracks.
using GETSYS you can copy system track images from previous installations
