Boot Manager
This appendix provides a description of the RICi-E3, RICi-T3 boot procedure for
downloading software using an ASCII terminal.
The RICi-E3, RICi-T3 software is stored on a flash memory in two sections, the
boot sector and the file system. The boot sector contains a boot program that
calls the program itself from the file system.
The file system can hold two compressed copies of the RICi-E3, RICi-T3 code. One
copy is referred to as the operating file, and the other one as the backup file.
The operating file is the default-executable RICi-E3, RICi-T3 code. The backup file
is used whenever the operating file is absent or corrupted.
