NF BC Booting and Resetting the Reader<br />

9<br />

This chapter describes how to boot and reset the reader, set a password for advanced<br />

reader commands, put the reader in Storage mode, dump the contents of<br />

conventional memory to a host computer, and load the reader’s flash memory.<br />

Booting the <strong>JANUS</strong> Reader<br />

The bootstrap process for the <strong>JANUS</strong> reader is similar to the bootstrap process<br />

for a PC. However, while you often boot a PC, you seldom boot the reader. The<br />

next sections explain how and why you perform these tasks:<br />

• Warm Booting the Reader<br />

• Cold Booting the Reader<br />

• Executing or Skipping the Startup Files<br />

Warm Booting the Reader<br />

You may warm boot the reader to run a startup file that has changed. You may<br />

also warm boot to start Interlnk.<br />

A warm boot performs a power-on self test (POST) to ensure that the hardware<br />

and peripherals are operational, runs CONFIG.SYS and AUTOEXEC.BAT, and<br />

displays the DOS prompt. The contents of the physical RAM drive (drive E)<br />

remain intact.<br />

Caution<br />

Do not press any keys while the reader is performing a warm boot or you may<br />

lose data.<br />

Conseil<br />

N'appuyez pas sur des touches pendant que le lecteur se réamorce, sinon vous<br />

pouvez perdre des données.<br />

• Press and release these keys in order:<br />
