Booting the Terminal
Powering the terminal on does not boot the system or initialize the program or data. To
initialize the terminal, perform either a warm boot or cold boot.
Warm Boot
A warm boot resets the operating system while preserving the program and data on the RAM
disk. This process is similar to pressing the <Ctrl+Alt+Del> keys on a PC, except that it does
not clear the system’s memory. To perform a warm boot:
For the 35-Key terminal:
" Power the terminal off
" Press and hold <F> and <J>
" Press and release <PWR>
" Release <F> and <J>.
For the 46-Key terminal:
" Power the terminal off
" Press and hold <4> and <5>
" Press and release <PWR>
" Release <4> and <5>.
The terminal displays configuration information, copyright, RAM size, and expanded
memory RAM size. Other information displayed depends on the operating system, installed
device drivers, and AUTOEXEC.BAT commands. If this warm boot procedure fails to restart
the terminal, use the Cold Boot procedure.
Cold Boot
A cold boot fully resets the system and clears memory, including the RAM disk. Any
programs and data stored in memory or on the RAM disk are deleted. Nonvolatile memory
(NVM - the Application EEPROM) is not affected. If the cold-boot procedure fails to restart
the terminal, see Chapter 7, Error Recovery and Troubleshooting.
Caution
This procedure permanently erases all data and software in the terminal un-
less they reside in NVM. Contents of RAM are lost.
