Appendix B
Boot Manager
B.1 Introduction
This appendix provides a description of the ACE-3105, ACE-3205 boot procedure
via an ASCII terminal for downloading the boot software
.
The ACE-3105, ACE-3205 software is stored in the flash memory of two sections:
the boot sector and the file system.
•
Boot sector – contains a boot program that ACE-3105, ACE-3205 loads
initially. Once loaded, it calls up the rest of the program from the file system.
• File system – contains up to two compressed copies of the unit's application
code. One application copy is called the operating file, and the other (if
exists) is called the backup file. The operating file is the default-executable
ACE-3105, ACE-3205 application code. The backup file is used whenever the
operating file is absent or corrupted.
•
The boot code of the device should not be tampered with. It should ONLY be
handled by authorized personnel, or after contacting RAD Technical Support.
• Formatting the file system means deleting all files in the system, including the
software-operating main, backup and configuration files.
B.2 Booting ACE-3105, ACE-3205
ACE-3105, ACE-3205 boots up automatically. After powering up, no user
intervention is required, except when the user wishes to access the file system to
modify or update the ACE-3105, ACE-3205 application software.
Boot Sequence
The following is a description of the boot sequence. If the system is working
normally, the entire process is completed within two minutes as follows:
1. The boot program searches for the operating file in the file system. If the file
exists, the program continues.
ƒ
If the operating file does not exist, the boot program searches for the
backup file. If the backup file is found, it is used instead of the operating
file and the boot process continues.
