On the JC ][ CPM-65 resides on 1 MB images on a SD card. Upon Boot the JC ][ first executes a
program in BOOT.SYS in the root directory of the SD. BOOT.SYS offers all bootable images found
in the Root directory for booting. The images must have the CPM-65 system in sectors 1 to 11.
The program then loads CPM-65 to memory, mounts the selected image as Drive A: via a BIOS call
and starts the CCP. Up to 4 images can be mounted with the utility SD-UTIL.
