LA-210 Ver. 1.5 Booting LA-210 B-1
Appendix B
Boot Manager
This appendix provides a description of the LA-210 boot procedure via an ASCII
terminal for downloading software.
The LA-210 software is stored in flash memory in two sections, in the boot
sector and in the file system. The boot sector holds a boot program that calls up
the rest of the program from the file system.
The file system can hold two compressed copies of the LA-210 code. One copy is
called the operating file, and the other is called the backup file. The operating file
is the default-executable LA-210 code. The backup file is used whenever the
operating file is absent or corrupted.
B.1 Booting LA-210
LA-210 boots up automatically. After powering up, no user intervention is
required, except when the user wants to access the file system to modify or
update the software or the LA-210 configuration.
Accessing the Boot Manager
The Boot Manager menu is an option that allows the user to perform basic file
transfer operations. These operations are all optional.
³ To access the Boot Manager menu:
• Press <Enter> several times immediately after powering up LA-210.
The Boot Manager menu is displayed (see
Figure B-1 ).
